I generally prioritize external eartips over stock eartips with IEMs, and I usually get the best results with a good pair that I find compatible. The most important of these for me is the SpinFit W1. You know, not every upgrade has to be electronic. Sometimes the biggest improvement comes from simple parts that connect your music directly to you.

I've been trying out the new SpinFit AuraFine model, eartips specifically designed for Apple AirPods Pro 3 users, for a while now, and I've found it to be quite good, just like the W1.

Combining SpinFit's patented engineering with a completely redesigned connection system, AuraFine significantly improves comfort, stability, and acoustic performance without altering the sound character of the AirPods Pro 3. I think the bass, in particular, is even better with these tips than the original.

AuraFine features SpinFit's new CPA17 click adapter. Unlike traditional replacement ear tips, the adapter locks securely into place, creating a reassuring factory connection while maintaining easy insertion and removal. The result is a stable fit that feels like it belonged to the earbuds from day one.

Comfort has always been one of SpinFit's strengths, and with AuraFine on the AirPods Pro 3, they've managed to take it even further. The company's patented 3D Axis technology allows each ear tip to naturally rotate within the ear canal, adapting to subtle movements while reducing pressure during extended listening sessions.

Whether you're commuting, working, exercising, or simply enjoying a long playlist, the ear tips will consistently fit your ears.

Completing this flexibility is SpinFit's newly developed Aura Rib dual-density structure. A softer outer layer gently conforms to the ear for exceptional comfort, while the reinforced inner support maintains structural stability. Together, they create a secure acoustic seal that remains consistent even during active movement, helping to preserve bass response, soundstage, and overall tonal balance.

One of AuraFine's most practical innovations is its integrated acoustic mesh. This precisely designed filter provides IP54 level protection against dust, sweat, and earwax while remaining acoustically transparent. AuraFine helps extend the lifespan of the AirPods Pro 3 while maintaining the clarity and detail that users expect.

SpinFit is also a manufacturer that understands that no two ears are exactly alike. In addition to Apple's original sizing, AuraFine offers a special MS size positioned between Medium and Small. This additional option allows many users to achieve a more accurate seal, providing enhanced passive isolation, greater comfort, and more consistent bass performance.

Each component is made from high purity, hypoallergenic silicone that feels incredibly soft against the skin and is durable enough for everyday use. The overall experience is incredibly natural, almost making you forget you're wearing earbuds.

AuraFine takes comfort to the next level without altering the carefully tuned sound signature of the AirPods Pro 3. By improving the seal, reducing unwanted movement, and maximizing long term comfort, it helps listeners experience this setting more consistently. While the difference is subtle in concept, you can immediately notice it in daily use.

For AirPods Pro 3 owners who want to unlock their full potential without changing their earbuds, SpinFit AuraFine represents an example of the meticulous engineering that has made SpinFit one of the most respected names in premium ear tips.

Electro Audio World's Take :

The legendary 770 series, which I admired so much in its early installments, is back! This time, it's finally here in our review, much better tuned.

The DT 770 PRO became legendary because it did its job great and was so affordable. For over forty years, it has been known as one of the most recognizable closed back headphones in recording studios around the world. I smile now thinking about what I did to buy it back then, but it was worth it. Because thanks to the engineers who first produced the DT770 series, musicians relied on it. 

Content creators embraced it. Audio enthusiasts discovered it. I think very few headphones on the market have had this level of importance for so long almost 41 years. Replacing such an icon is never easy. Instead of reinventing the formula, Beyerdynamic's engineers have chosen a much smarter approach in the new model. The DT 770 PRO X retains everything that made the original famous, while offering meaningful improvements in key areas.

Throughout this review, I primarily paired the DT 770 PRO X with the Sony NW ZX507 and FiiO M33 R2R audio players. These two high quality digital audio players complement the headset perfectly, highlighting its different facets. The M33 R2R emphasizes its organic character and note density, while the ZX507 highlights its effortless musicality and smooth tonal balance.

Build Quality

The moment you hold the DT 770 PRO X in your hand, you immediately recognize its legacy. Everything felt reassuringly familiar. The steel headband remains extremely robust. The aluminum fittings inspire confidence. I love the iconic grey velvet ear cushions; they remain among the most comfortable available at any price point. 

This is still undoubtedly a Beyerdynamic. The biggest practical improvement is the detachable mini XLR cable. Owners of older DT770 models have been requesting this for years, and Beyerdynamic finally listened. However, I still think it's a little difficult to remove.

Comfort remains one of the strongest reasons I choose these headphones. Even after hours of uninterrupted listening, I haven't experienced any excessive pressure or heat buildup. The compression feels secure enough for studio work without being tiring. 

As expected, passive isolation is excellent. Whether you're recording vocals, editing video, or listening in a noisy environment, the DT770 PRO X effectively isolates external distractions without the need for active noise cancellation. Perhaps that's why this series has become legendary..

Sound Performance

I think the easiest way to describe the DT770 PRO X is balance. It's not a character with reference neutrality. It's not overly exciting either.

Compared to the classic DT770 PRO, the new model's sound is noticeably more refined. The bass feels tighter. The mid frequencies become more prominent. The treble remains detailed but is significantly softer than previous generations. In the old series, the 8kHz region was a bit sharp, but now it's better. Most importantly, the overall presentation feels more consistent.

The new STELLAR.45 driver has managed to deliver faster transient response, lower distortion, and improved tonal consistency across the frequency spectrum. These improvements are immediately noticeable regardless of the source. 

Bass

Bass performance is one of the DT770 PRO X's greatest strengths.

It extends remarkably deep while remaining disciplined and clear. The sub-bass effortlessly reaches the lowest octaves without becoming dominant. Kick drums feel physical. Bass guitars exhibit excellent texture. Electronic music benefits from a satisfying effect without sacrificing control. You know, many closed headphones create excitement with an overemphasis on mid bass, but not with the DT770 PRO X. The bass remains clean, layered, and extremely high resolution.

With the FiiO M33 R2R, the low frequencies gain an added fullness and natural warmth, making the presentation even more engaging. The Sony ZX507 offers a slightly softer approach, prioritizing musical flow over absolute authority. Both pairings were extremely enjoyable.

Midrange

Historically, the DT770 was often criticized for its somewhat subdued mid frequencies. The DT770 PRO X addresses this criticism perfectly, correcting the shortcomings.

Vocals now sound fuller and more natural. Male voices carry a convincing weight. Female vocals exhibit excellent clarity without being overly prominent. Acoustic instruments particularly benefit from the improved mid frequency balance. Pianos have a realistic harmonic structure. Electric guitars stand out in dense mixes without becoming aggressive. Strings sound smooth and believable.

The M33 R2R further enhances this area by offering added note density and harmonic richness. Taken together, the presentation becomes wonderfully organic while maintaining impressive resolution.

Treble

Treble has always defined Beyerdynamic, and its engineers have never shied away from delivering exceptional detail.

Fortunately, the DT770 PRO X delivers significantly better treble frequencies than several previous Beyerdynamic generations. There's still plenty of sparkle. There's still exceptional extension. Micro details are extremely easy to identify. Yet, the upper frequencies rarely become tiresome even after 4-5 hours of listening. 

Cymbals exhibit a realistic glow. Ambient information comes through naturally. The air between instruments contributes significantly to the expansive presentation. Listeners who previously found older Beyerdynamic models a little too bright will likely appreciate the more mature tuning found here.

Soundstage and Imaging

Closed back headphones rarely excel in terms of soundscape. I think the DT770 PRO X is one of the exceptions in its class.

The soundstage extends far beyond the headphones themselves, providing a surprisingly open presentation for a closed design. The sense of depth is particularly impressive. Layering remains excellent. Instrument placement is remarkably accurate. Games, soundtracks, and live recordings all benefit from the headphones' exceptional imaging capabilities.

The FiiO M33 R2R creates a larger and more holographic presentation from the two sources. The Sony ZX507 offers a slightly more intimate but wonderfully integrated soundstage. Both combinations demonstrate the capabilities of the DT770 PRO X when paired with quality source equipment.

Comparisons

1- Sony MDR MV1 vs DT 770 PRO X

While both headphones target professionals, their design philosophies are fundamentally different.

The Sony MDR MV1 is an open back headphone primarily developed for immersive audio production, spatial mixing, and critical monitoring. Its presentation instantly creates a more spacious feel, producing a wider and airier soundstage compared to the DT 770 PRO X.

However, Beyerdynamic reminds us why closed back headphones hold a significant place in professional audio.

The bass is noticeably stronger. The sub bass extends deeper, creating more physical impact while maintaining excellent control. Electronic music, modern rock, and cinematic film soundtracks sound fuller and more engaging on the DT 770 PRO X.

The mid frequencies are also different.

The MDR MV1 delivers vocals with exceptional neutrality and transparency, making it an excellent choice for mixing and mastering, while the DT 770 PRO X offers a bit more warmth and fullness, creating a more enjoyable presentation during long listening sessions.

The treble also presents an interesting contrast. While Sony, as always, aims for smoothness and balance, Beyerdynamic retains its characteristic clarity and breadth. Fortunately, the DT 770 PRO X avoids the sharper treble peaks found in some previous Beyerdynamic models, which significantly improves listening.

If your primary goal is studio mixing in a quiet environment, the MDR MV1 remains an outstanding tool.

If you need isolation, stronger dynamics, and a headset that performs equally well for both professional work and everyday music enjoyment, I would choose the DT 770 PRO X without hesitation. 

2- Sennheiser HD 620S vs DT 770 PRO X 

The HD 620S might be one of the most interesting competitors to the DT 770 PRO X, as both aim to deliver an open sounding presentation from a closed back design.

The Sennheiser makes an immediate impression with its natural mid frequencies and extremely realistic vocal reproduction. Acoustic instruments have a beautiful tonal accuracy, making classical music and jazz particularly enjoyable. The DT 770 PRO X responds with more energy and stronger dynamics.

The bass goes deeper and has noticeably more impact. The presentation feels faster, livelier, and more engaging in modern genres.

The treble extension, as you might expect, is again slightly in favor of Beyerdynamic.

There's more sparkle, more air, and a bit more perceived detail capture. At the same time, the HD 620S sounds a bit softer and more comfortable, especially in bright recordings.

The soundstage performance is surprisingly close. The HD 620S creates an impressively open presentation for a closed headphone, but the DT 770 PRO X matches this quite well by adding superior imaging sensitivity and stronger instrument placement.

When paired with the FiiO M33 R2R, the DT 770 PRO X gains added warmth and note density, becoming even more competitive against Sennheiser's natural organic presentation.

Choosing between these two ultimately comes down to personal taste.

Listeners seeking neutrality and vocal realism might gravitate towards the HD 620S. Those wanting more versatility, stronger bass performance, and a more dynamic presentation will most likely opt for the DT 770 PRO X. I really liked both of them as closed headphones.

Pros

Better overall tuning than its predecessor with excellent tonal balance

Powerful, deep and highly controlled bass response

Significantly improved mid frequencies compared to the previous DT 770 series

More detailed but softer treble than many previous Beyerdynamic models

Excellent passive isolation for studio and portable use

Extremely comfortable velvet ear cushions suitable for long listening sessions

New detachable mini XLR cable greatly increases practicality

STELLAR.45 driver offers excellent resolution and low distortion

Wide soundstage for a closed back headset

Impressive imaging and instrument separation

Easily driven from both portable players and desktop equipment

Build quality designed for years of professional use

Cons

Still larger than many modern portable headphones

Trebles remain somewhat energetic for listeners who prefer a darker sound signature

Fixed earcup design may not fit every head shape

Carrying case not included, comes only with a cloth pouch. Analytical listeners may still prefer the fully open design.

The new mini XLR cable should have had an easier detachable socket.

Final Verdict

Few headphones have managed to reach the level of respect the original DT 770 PRO earned in the last forty years. This legacy also created enormous expectations.

Fortunately, the DT 770 PRO X lives up to those expectations, in my opinion.

Instead of trying to reinvent an icon, Beyerdynamic has focused on improving every area that matters most. The bass is tighter and more controlled. The midfrequencies are more natural and expressive. The treble remains detailed but significantly more mature. Add in the detachable cable, the excellent STELLAR.45 driver, and the same legendary build quality, and you have a headphone that feels truly modern while respecting its legacy.

Throughout my review, the DT 770 PRO X never felt limited to a single purpose. It was equally convincing in situations such as audio editing, enjoying live recordings, exploring complex orchestral works, or simply relaxing with your favorite album.

It remains an excellent monitor headphone for professionals.It offers a mature and engaging listening experience for audiophiles.

For everyday music lovers, it provides comfort, reliability, and sound quality that will satisfy them for many years. I would definitely recommend that friends who have never listened to or bought Beyerdynamic before try it somewhere. That's what oldschool was all about…

TRN, based on my testing and impressions so far, has a strong reputation for producing affordable headphones that deliver impressive technical performance. While many of their previous products focused on aggressive V shaped tunings, the new TRN Shell represents a much more mature approach. The Shell combines four different driver technologies in a surprisingly consistent and musical presentation. The Whaleshark model I listened to before had the same driver arrangement but with a more balanced tuning; this one is tuned with a slightly different tonality.

Inside each earbud is a sophisticated hybrid configuration consisting of a 10.5mm Beryllium Coated Dynamic Driver, an 8mm PET Dynamic Driver, a 6mm Titanium Coated Dynamic Driver, and one of TRN's own 6mm Micro Planar Drivers. Each driver has a specific task, allowing the Shell to produce dynamic, detailed, and energetic sound while remaining remarkably balanced for its price. After listening for a few weeks, I want to say that I was surprised not only by the amount of detail it captures, but also by how well it sounds like a more expensive IEM. Of course, this is limited to a certain level. To me, it sounds more like a $100-150 IEM than a $60-65 one. I think that alone is a result worthy of praise.

Driver integration is again quite good, transitions between frequency ranges are as smooth as possible, and I didn't get the feeling that one driver dominated the other. In the approximately $65 price range, I'm starting to think that the TRN Shell is currently the best tuned hybrid IEM on the market.

The included modular cable is significantly better than those normally included in this price range. It feels soft, resists tangling well, and the interchangeable 3.5mm and 4.4mm balanced plugs are secure and easy to switch between. With a wide range of ear tips and adjustment nozzles, users can customize both comfort and sound without buying additional accessories. However, as always, I prefer to use the Spinfit W1 in this test as well.

*** To read the full review, including source matching and comparisons with other IEMs, click here.

Pros: 

Best tuned hybrid in the $65 price range
Stable driver matching despite complex four driver configuration
Deep, textured and well controlled bass
Natural and high resolution mid frequencies
Detailed but not overly tiring highs
Wide soundstage with accurate imaging
Superior quality and all metal construction
Excellent modular cable with interchangeable plugs
Three tuning nozzles provide meaningful sound customization

Cons: 

Given the overall quality of the package, the stock cable could have been better
Glossy metal housings easily show fingerprints
Not many downsides at this price.

Electro Audio World's Take

My First Impressions :

When Beyerdynamic released the DT270 PRO, to be honest, I didn't expect it to become one of my favorite compact closed back studio headphones. Marketed as an entry level professional monitor, it offers a tonal balance, comfort, and musical enjoyment far beyond its price.

While not the most analytical headphone in Beyerdynamic's lineup, it has proven to be one of the most sensible products the company has released in recent years. Fortunately, the new DT275 PRO takes this philosophy a step further in the realm of isolation. How do you achieve perfect passive isolation in an affordable studio monitor?

At first glance, very little seems to have changed. The overall design, compact form factor, and professional look remain familiar. It's still clearly a headphone designed for streamers, engineers, content creators, and musicians who wear headphones for long hours every day. However, after just a few listening sessions, it becomes clear that Beyerdynamic wasn't trying to change the DT270 PRO, but to improve it.

If I had to summarize the difference in a single sentence, I would describe the DT270 PRO as a more comfortable and slightly warmer musical sibling, while the DT275 PRO has enhanced sound isolation, resulting in a more balanced sound and ultimately closer to what many professionals expect from a true monitor headset.

The DT270 Pro has a slightly more open soundstage and is studio focused, while the DT275 Pro is a variant designed for those who want better isolation in outdoor environments. Of course, this by no means means it has a clinical sound. On the contrary. One of the features I've always appreciated in Beyerdynamic's professional products is their ability to remain enjoyable even outside the studio.

The DT275 PRO continues this tradition exceptionally well. It's more of a work focused version with a more isolation oriented setup compared to the DT270 PRO, and as a result, it never loses the musicality that makes long listening sessions enjoyable. On the contrary, it better isolates the listener from the environment.

This balance is what made the headset appealing to me because it's something very few products struggle to achieve. Many studio headphones prioritize accuracy at the expense of listening pleasure, while consumer focused headphones often sacrifice tonal integrity for excitement.

The DT275 PRO aims to bridge these two worlds, providing reliable presentation during editing while remaining engaging enough for everyday music listening. That's exactly how I approached this review.

Who is the Beyerdynamic DT 275 PRO Designed For?

While many studio headsets are optimized for mixing and mastering in quiet control rooms, the Beyerdynamic DT 275 PRO takes a completely different approach. It's designed for professionals working in dynamic, noisy environments where accurate monitoring is essential and distractions shouldn't interfere with critical decisions. Proof of this is its powerful passive isolation with leather pads.

At the heart of the DT 275 PRO is high passive noise isolation, allowing users to focus on the sound they need to hear rather than the surrounding environment. Whether monitoring speech, checking signal integrity, or evaluating levels during a live production, the DT 275 PRO ensures that external noise is minimally distracting. The headset is particularly well suited for video production crews and content creators working on film sets or outdoor shoots. In these situations, monitoring dialogue, wireless microphone performance, and ambient sound requires excellent isolation and a neutral, balanced sound signature. Its lightweight over ear design ensures it's comfortable enough for long production days while remaining compact enough for transport between locations. I also think it's a very suitable headset for those who make YouTube videos.

For live sound engineers and front of stage (FOH) professionals, the DT 275 PRO is more than adequate for reliable monitoring in venues filled with audience noise and powerful PA systems. Its balanced tuning helps engineers accurately assess speech clarity, signal quality, and overall sound balance, even if the environment itself isn't silent.

I think this headset would be equally valuable for DJs and mobile performance artists. Anyone involved in this knows that quick cueing, precise beat matching, and tracking the next track require headsets that provide effective isolation while remaining lightweight and comfortable. The rotating earcups allow for quick single ear monitoring, making the DT 275 PRO an ideal aid in the DJ booth, which is another of its versatile uses.

Another important target audience is field recording professionals. Journalists, broadcast engineers, documentary filmmakers, and field sound recorders often work in unpredictable acoustic conditions. The DT 275 PRO allows users to confidently monitor recordings without being overwhelmed by ambient noise, helping them identify unwanted interference before it becomes a problem.

Beyond its acoustic performance, the DT 275 PRO is designed with the practical realities of professional work in mind. Compact swivel earcups make it easy to carry, while the lockable, detachable cable can be attached to either the left or right earcup depending on the user's workflow or equipment setup. This flexibility is particularly useful in demanding production environments where cable routing is important.

Long term reliability is another key feature. Soft ear cushions and a lightweight frame ensure lasting comfort during extended use, while replaceable components ensure the headset remains in service for many years instead of being discarded when individual parts wear out.

The Beyerdynamic DT 275 PRO is built as a purpose built professional monitoring tool. It's designed for creators, engineers, broadcasters, and performing artists who need reliable and accurate monitoring in challenging environments where clarity, isolation, portability, and durability are as important as sound quality.

Instead of evaluating the DT275 PRO solely as a studio tool, I wanted to understand how it performs as a versatile headset for both entry level professionals and entry level audiophiles. For a few weeks, I used it with three Sony Digital Audio Players that I know very well:

Sony WM1A, Sony NW-ZX507, and Sony NW-A45.

Each of these three players presents music differently. The WM1A offers a rich, highly refined, and expansive presentation. The ZX507, running on the Android operating system, strikes a perfect balance between detail and musicality, becoming a versatile everyday source. The compact A45, despite its age, continues to impress me with its smooth, enjoyable sound and portability.

By using three different Sony players, I was able to evaluate not only how easy the DT275 PRO is to drive, but also how consistently it maintains its sound character across sources with varying output capacities and tonal presentations.

The music selection encompassed everything I normally use when evaluating headphones: classical orchestral recordings, jazz ensembles, acoustic performances, male and female vocals, progressive rock, electronic music, and live recordings. Instead of focusing on individual test tracks, I took the time to listen to full albums, because I believe prolonged listening tells you much more about a pair of headphones than quick A/B comparisons.

The DT275 PRO's strengths gradually emerge thanks to its balance, consistency, and lack of apparent weaknesses. It's one of those headphones that becomes more enjoyable with use, and that's a quality I value far more than an exaggerated first impression.

Electro Audio World's Take

My First Impressions :

When Beyerdynamic released the DT270 PRO, to be honest, I didn't expect it to become one of my favorite compact closed back studio headphones. Marketed as an entry level professional monitor, it offers a tonal balance, comfort, and musical enjoyment far beyond its price.

While not the most analytical headphone in Beyerdynamic's lineup, it has proven to be one of the most sensible products the company has released in recent years. Fortunately, the new DT275 PRO takes this philosophy a step further in the realm of isolation. How do you achieve perfect passive isolation in an affordable studio monitor?

At first glance, very little seems to have changed. The overall design, compact form factor, and professional look remain familiar. It's still clearly a headphone designed for streamers, engineers, content creators, and musicians who wear headphones for long hours every day. However, after just a few listening sessions, it becomes clear that Beyerdynamic wasn't trying to change the DT270 PRO, but to improve it.

Electro Audio World's Take :

Build Quality, Design, and Comfort

Beyerdynamic has always had products that embrace a simple industrial design, and I think the AMIRON 300 follows this philosophy beautifully, but the quality is quite good. The Amiron 300 offers a clean and elegant look that gives it a distinctly mature feel. Every surface, curve, and material choice reflects attention to detail, giving the impression of a product designed for longevity. The charging case continues this minimalist approach.

Compact enough to fit in a pocket, yet robustly constructed, the case inspires confidence every time it's opened. Wireless Qi charging and USB-C support make daily charging effortless, while the magnetic closure and secure earbud placement create a reassuring sense of quality.

Comfort is equally impressive. It connects to the iPhone 14 Pro Max the moment you open the lid it happens quite quickly.

Weighing just 4.4 grams per earbud, the AMIRON 300 feels almost invisible during extended listening sessions. Beyerdynamic includes five different sizes of elliptical silicone ear tips, allowing almost any listener to achieve a perfect seal. Finding the right tip size is particularly important, as proper placement significantly improves bass response and overall tonal balance.

During several listening sessions exceeding four hours, I experienced no pressure points or listening fatigue stemming from the physical design itself. Whether sitting at my desk, walking outside, or exercising, the earbuds always stayed securely and comfortably in place.

The IP54 certification provides added confidence for outdoor use and gym sessions without compromising the design's elegant look.

A thoughtful detail I particularly appreciated is the subtle protrusion integrated into each earbud; this facilitates touch interaction without having to constantly search for the control surface.

Speaking of controls, the touch operation is fast, responsive, and highly customizable via the Beyerdynamic app. Every movement was reliably registered throughout my tests, and after a short learning curve, playback, ANC modes, and volume adjustments became completely intuitive.

The wear detection feature further enhances the overall user experience, automatically pausing playback the moment either earbud is removed.

Everything about the AMIRON 300 feels cohesive. It's exactly the level of app functionality I've been expecting from Beyerdynamic.

Electro Audio World's Take :

First, I want to mention that since the review includes comparisons with different IEMs, I wanted to share this here as well.

I've reviewed products like the FiiO LINK TWS before, but their performance didn't satisfy me enough to publish a review. With the Link TWS, FiiO aims to transform our favorite IEMs into premium true wireless earbuds without compromising sound quality.

Powered by Qualcomm's flagship QCC5181 Bluetooth platform and the Japanese AKM AK4333 DAC with integrated headphone amplifier, this product promises better wireless stability, higher sound quality, lower latency, and greater compatibility compared to previous generations.

With the Link TWS, I tested IEMs from my collection with diverse characteristics, such as the Moritz Audio Enzo, FiiO Snowsky OAK Nano, and Ziigaat Arcanis. I used them daily for several weeks with an iPhone 14 Pro Max and FiiO M33 R2R as Bluetooth audio sources, and now my opinion on this has changed.

I realized that an audiophile might never want to go back to ordinary standalone wireless earbuds. Now I definitely think that a quality product like the Link TWS should be in every audiophile's bag. I think this is the next level..

First Impressions

After connecting the LINK TWS to IEMs, it felt more like a natural extension of the IEM than an aftermarket accessory, and it felt quite stylish.

The modular connection system is one of the smartest improvements FiiO has introduced. Having both MMCX and 2 pin connectors in the same package eliminates one of the biggest frustrations experienced by previous UTWS users. I have IEMs that use both connector types, and being able to switch between them without buying separate adapters makes the LINK TWS much more practical.

The charging case is equally impressive. Its overall dimensions are compact enough for everyday pocket use, and the addition of an OLED charging information display to the case simplifies the user experience. Battery status, pairing information, and charging progress are now instantly visible instead of relying on small indicator LEDs, which I think is quite technological.

These may be small details. However, they make the LINK TWS feel much more refined than previous generations.

Sound Signature :

One of the biggest reasons why the LINK TWS delivers noticeably better sound than most wireless adapters is, in my opinion, its high quality hardware architecture.

Instead of relying solely on the Bluetooth chipset for digital conversion, FiiO has equipped the LINK TWS with the AKM AK4333 DAC and headphone amplifier, which works in conjunction with Qualcomm's flagship QCC5181 Bluetooth platform. This is quite impressive. I think it owes its overall quality to this.

This combination has managed to give the LINK TWS a sound character that is surprisingly close to that of a compact wired DAC.

The AK4333 has always been one of my favorite portable DAC implementations because it avoids the sterile presentation that some mobile ESS based designs sometimes exhibit. It's a rather technical presentation.

Here, it exhibits a smooth, dynamic, and remarkably natural character.

The bass carries a satisfying weight without becoming dominant. Acoustic recordings retain excellent texture and realism, while electronic music has enough authority to give it a convincing impact.

The sub bass extends deeper than I expected from a wireless adapter, but remains controlled and disciplined.

Where the LINK TWS interestingly shines is in the mid frequencies. You know, generally, wireless systems have lower transmission quality than wired ones, and this negatively impacts vocal performance in particular.

Voices sound more open, clean, and emotionally impactful to my ears. Male voices have a convincing fullness, while female vocals remain beautifully transparent without being overly prominent. Instruments naturally occupy their own space, allowing complex arrangements to breathe without being choked.

The treble is also quite good, in my opinion. The LINK TWS offers excellent extension with a refined sense of air. Cymbals naturally fade out, string harmonics remain delicate, and long listening sessions never become tiring. In my opinion, this is exactly the sound transmission quality that an "audiophile Bluetooth adapter" should produce.

Pros: 

Excellent sound quality for a wireless adapter
Natural and musical AK4333 DAC application
Superior Bluetooth stability (no connection ever dropped)
Excellent aptX and AAC performance
Both MMCX and Two Pin connectors included in the box
Comfortable and secure fit
These physical buttons definitely work better than other touch controls
Useful display on the charging case
Powerful FiiO Control application with parametric EQ
Excellent call quality
Wireless charging support

Cons: 

Transparency mode still lags behind high end mainstream TWS models
Soundstage is slightly smaller than a good wired DAC
Takes some time to learn all the button shortcuts
High price compared to ordinary wireless adapters, but high quality

The AK4333 has always been one of my favorite portable DAC implementations because it avoids the sterile presentation that some mobile ESS based designs sometimes exhibit. It's a rather technical presentation.

Here, it exhibits a smooth, dynamic, and remarkably natural character.

The bass carries a satisfying weight without becoming dominant. Acoustic recordings retain excellent texture and realism, while electronic music has enough authority to give it a convincing impact.

The sub bass extends deeper than I expected from a wireless adapter, but remains controlled and disciplined.

Where the LINK TWS interestingly shines is in the mid frequencies. You know, generally, wireless systems have lower transmission quality than wired ones, and this negatively impacts vocal performance in particular.

Voices sound more open, clean, and emotionally impactful to my ears. Male voices have a convincing fullness, while female vocals remain beautifully transparent without being overly prominent. Instruments naturally occupy their own space, allowing complex arrangements to breathe without being choked.

The treble is also quite good, in my opinion. The LINK TWS offers excellent extension with a refined sense of air. Cymbals naturally fade out, string harmonics remain delicate, and long listening sessions never become tiring. In my opinion, this is exactly the sound transmission quality that an "audiophile Bluetooth adapter" should produce.

First Impressions: 

First, I want to mention that since the review includes comparisons with different IEMs, I wanted to share this here as well.

After using the Tanchjim Space Pro with my iPhone 14 Pro Max for a few weeks and then pairing it with my TempoTec V3 Blaze as a USB DAC transfer device, I found myself reaching for the Space Pro more often than I expected.

Tanchjim has a reputation for creating balanced products, and the Space Pro follows exactly that philosophy. Behind its compact aluminum body lies a fully balanced architecture based on dual Cirrus Logic CS43198 DAC chips and dual SGM8262 amplifier stages; this architecture provides enough power for demanding portable headphones while also managing to remain completely silent with highly sensitive IEMs.

Sound Signature

I wouldn't call the Space Pro warm or analytical.

I think it would be more accurate to describe it as neutral, with a subtle touch of musical sweetness that prevents it from sounding clinical. This is what I expect from a well implemented Dual CS43198 design.

The bass is tight without being light, the mid frequencies are transparent while preserving natural vocal texture, and the treble stretches beautifully but never becomes sharp.

The background remains as black as possible, so small details emerge naturally rather than being forced to the forefront.

The Space Pro focuses on maintaining overall tonal balance. This makes it surprisingly versatile.

Whether I switch from acoustic jazz to orchestral recordings, modern electronic music, or classic rock, the character of the recording remains intact. The DAC never tries to impose its own personality on the music.

I appreciate this level of restraint more and more each year.

Bass

The low frequencies immediately reveal the advantages of the dual CS43198 implementation. The bass goes deep with excellent extension but refuses to swell. The kick drums have convincing physical impact.

The bass guitars remain textured instead of blending into a single wall of warmth.

The electronic sub bass carries a satisfying authority without masking the vocals. Listeners seeking extreme warmth might find it a little restrained, but anyone looking for realistic bass reproduction will immediately recognize its strengths.

Midrange

Vocals are presented with exceptional honesty. Male voices sound rich without becoming thick. Female vocals remain smooth, preserving every subtle breath and intonation. Strings exhibit a realistic harmonic structure. Pianos carry convincing body without becoming overly loud. The mid frequencies never veer into artificial warmth or analytical dryness.

Treble

The treble is one of this DAC's strongest points. The extension is excellent. Air remains abundant. Micro details emerge effortlessly. But none of this comes at the expense of comfort. Poor recordings remain listenable.

High quality recordings reveal an extraordinary amount of ambient information without sounding artificially bright.

Cymbals fade naturally. Violin harmonics remain smooth. Electronic effects retain their brilliance without becoming harsh. Even after hours of uninterrupted listening, I didn't feel tired. This is a rare achievement for a high resolution portable DAC.

Soundstage and Imaging

The breadth is excellent. Impressive in depth.

The sense of height becomes surprisingly pronounced in well recorded live albums. Layer separation remains stable during complex passages. Instrument placement feels delicate, not exaggerated.

The extremely low background noise plays a significant role here.

The silence between notes creates the space that allows the visualization to breathe. The presentation feels convincing, rather than spectacular. This separation becomes more valuable the longer you listen.

My First Impressions :

We previously reviewed the Sivga QUE UTG version. Now, I wanted to take a look at the first version of the series, the QUE model.

The QUE series focuses on natural tone, balanced tonality, and musical harmony, but the UTG version, in my opinion, had too flat a tuning. The QUE, on the other hand, reminds me why even many experienced audiophiles appreciate a well tuned single dynamic driver, even in the affordable IEM category. Instead of separating every detail under a microscope, it can present the music as a complete performance where every instrument feels connected and organic.

At the heart of the QUE is a meticulously tuned 10mm Beryllium coated dynamic driver that uses a high stiffness diaphragm optimized for low distortion and fast transient response. Sivga has done a very good job here by opting for the simplicity of a single full range transducer. The result is, in my opinion, an excellent phase match, convincing tone, and almost flawless integration from bass to treble among IEMs up to $100.

Over the past few weeks, I've been using the Sivga QUE with a variety of digital audio players, including the FiiO M33 R2R, Sony NW ZX507, TempoTec V3 Blaze, and Surfans F35. I also directly compared it to strong competitors like the Kefine Arnar, Tanchjim Fola, and Oriveti bleqk Dynabird.

After more than 100 hours of listening, including jazz, blues, acoustic recordings, progressive rock, classical music, pop, and electronic tracks, I'm truly impressed with how enjoyable the QUE sounds. It may not be the most analytical IEM in its category, but it encourages longer listening sessions, which is often a sign of a perfect setup.

Design and Build Quality

Sivga has always been known for producing beautifully crafted products, especially with its wooden over ear and IEM’s, and this attention to detail is reflected in the QUE model.

The bodies are CNC machined from aluminum alloy; This always gives me a reassuring sense of solidity while remaining surprisingly lightweight during long listening sessions. Every edge is smoothly machined, and I really liked the build quality.

The front panel has a clean and simple industrial design that avoids unnecessary decorative elements. QUE is built with precise machining and refined surface treatment that makes you feel the quality.

The nozzle length is very well adjusted; this allows the earbuds to be placed securely in the ear canal without creating excessive pressure. A thin metal mesh protects the driver from dust and earwax while not restricting airflow.

The recessed 0.78mm 2 pin connectors provide a secure cable connection, allowing me to experiment with other cables I have. But I must say that the overall build quality feels significantly superior to many competitors in a similar price range. As for the cable quality, I would say that every IEM should have a cable of "at least this much quality".

Pros: 

Perfectly balanced, warm and neutral sound
Exceptional natural timbre and excellent tonal harmony
Rich and impressive mid frequency presentation
Tight, textured and well controlled bass
Smooth highs that cause virtually no listening fatigue
Excellent comfort for extended listening sessions
Premium CNC machined aluminum construction
High quality detachable cable with 0.78mm 2 pin connector
Scales noticeably with high quality DACs and DAPs
Exceptional value for listeners seeking musicality rather than pure analysis

Cons: 

Treble enthusiasts may want a little more high frequency and brightness
Soundstage depth is excellent, but width is not best in class
Detail capture lags slightly behind some similarly priced planar competitors

Electro Audio World's take:

The Kefine Arnar combines a large, custom designed 14.5mm planar magnetic driver with a Knowles Balanced Armature driver, creating a hybrid architecture that prioritizes balance, musicality, and subtlety.

The planar driver handles a large portion of the frequency spectrum with its characteristic fast response, while the Knowles Balanced Armature is dedicated to enhancing the upper mid and treble frequencies with the clarity, precision, and extension it's respected in the professional audio industry. Unlike many affordable hybrid IEMs where the balanced armature sounds disconnected from the main driver, the integration within the Arnar is remarkably consistent. 

* * * To read the full review, including source matching and comparisons with other IEMs, click here.

The transition between the planar diaphragm and the Knowles driver feels seamless, providing a natural sounding presentation regardless of music genre. After listening for over a week using only the balanced (4.4mm) output of my current digital audio player (mentioned in the review), I realized this is an IEM that encourages extended listening sessions without sacrificing the detail and transparency I expect from planar technology. In its price category, the Kefine Arnar is making waves as the only 1xPlanar and 1xKnowless Balanced Armature hybrid IEM currently on the market.

Design and Build Quality

Unlike many similarly priced competitors that rely on lightweight resin bodies, the Kefine Arnar is crafted from aerospace grade aluminum using CNC manufacturing techniques, resulting in shells that feel great in the hand. It remains surprisingly lightweight during extended listening sessions while also feeling robust.

The front panel features Kefine's signature decorative pattern inspired by traditional Chinese symbolism. The fine machining lines beautifully capture ambient light, giving the shells a refined look without being overly reflective.

The body dimensions are well adjusted. Despite having a relatively large 14.5mm planar magnetic driver, the headphones never feel excessively bulky in the ear (especially when compared to the MP145). The weight distribution is excellent, preventing pressure points even after hours of continuous listening.

Inside, the engineering deserves particular praise.The heart of the Arnar is a specially developed 14.5mm full range planar magnetic driver. Unlike traditional dynamic drivers, the planar diaphragm provides extremely fast transient response, low distortion, and exceptional control in bass and mid frequencies. 

Complementing this driver is a high performance Knowles Balanced Armature driver. The Knowles driver, instead of simply adding brightness, provides increased resolution, cleaner harmonic structure, improved vocal articulation, and better treble fineness.

Driver transitions remain virtually imperceptible, allowing the planar and Knowles drivers to act as a single, coherent transducer. Stainless steel nozzles feature a fine protective mesh while providing a secure grip for the ear tips. The Kefine also uses recessed 0.78mm two pin connectors for compatibility with aftermarket cables. I can say that I liked the overall build quality.

Pros: 

Good integration between the planar driver and the original Knowles Balanced Armature
Natural, neutral, and warm tonality with musicality
Fast, textured, and highly controlled bass response
Rich and realistic vocal presentation
Smooth, detailed, and fatigue free highs
Highly responsive to source upgrades
Premium CNC machined aluminum construction
Comfortable ergonomic design suitable for long listening sessions
Modular cable system with interchangeable 3.5mm and 4.4mm plugs
Three interchangeable adjustment nozzles provide significant adjustment flexibility
Remarkable value for money

Cons: 

Stock cable could be of higher quality
Listeners seeking powerful bass may prefer the dynamic driver design
The upper highs remain deliberately relaxed rather than aggressively energetic
The soundstage prioritizes realism rather than exaggerated breadth

Electro Audio World's Take - First Impressions :

Yes, I know this is TWS and that this isn't the right place to share it. But once you hear what I've heard, you'll understand exactly what I mean. Most audiophiles might not even bother reading this, but once they get a chance to listen, they'll realize they were biased.

Whenever I get the chance, I try to test the top versions of various brands and hear how far they've gone.

Features on TWS have become increasingly sophisticated, active noise cancellation has improved, battery life can reach far longer periods than once seemed possible, and wireless connectivity is more reliable than ever.

However, despite all these advancements, one area often remains a compromise point for serious audiophiles: sound quality.

As someone who spends most of my listening time with dedicated digital audio players, desktop amplifiers, and high performance IEM’s, I wasn't approaching a TWS product with true audiophile sound expectations. Convenience and portability are great, but they generally sound different from IEMs, with a noticeable difference in sound quality.

The Acoustune HSX One is a TWS that changed that thinking.

It's clear Acoustune approached this project differently than most manufacturers. They're entirely focused on sound quality.

The HSX One doesn't sound like a traditional consumer focused TWS earbud. Acoustune, known for producing serious IEMs, decided to create a wireless product without abandoning its core philosophy. And that difference becomes apparent the moment music starts playing. I think they succeeded.

Acoustune has equipped the HSX One with its proprietary third generation Myrinx dynamic driver, housed within a precisely machined aluminum acoustic chamber. While these specifications look impressive on paper, the real story begins with the tuning and technical execution. This is one of the highest resolution, clearest, and most technically capable true wireless earbuds I've ever heard.

Many modern TWS products create an illusion of detail by boosting high frequencies or exaggerating certain parts of the spectrum. The result is often a sound that initially seems impressive but eventually becomes tiring. The HSX One, however, feels expert level in detail capture. The resolution feels natural.

Every morning when I went for a walk, I used to take my IEM and a small DAP with me. Now I pair my iPhone 14 Pro Max with the HSX One. And I hardly feel the slightest lack of anything. This might sound like an exaggeration, but you'll definitely agree when you listen. The HSX One is so good that it compels you to do it. You can't deny what you hear.

Its technical capability stems primarily from driver quality, rather than tuning tricks. This distinction alone places it in a category far different from most of its competitors. You know, some IEM manufacturers still use a single dynamic driver in their thousands of dollar IEMs. So whether it's a single driver or 20 drivers, the sound quality absolutely depends on the pure quality of that driver.

Sound Performance :

If there's one area where the HSX One truly sets itself apart from the vast majority of the true wireless earbuds market, it's its technical performance, in my opinion.

Many TWS earbuds today use high bass, boosted upper mid frequencies, and bright highs to create excitement, instantly captivating an effect during a short listen. We've all experienced this. The problem is that this approach rarely translates into true long term listening satisfaction. Resolution and detail capture are often sacrificed in favor of a more dramatic presentation.

And that's where the HSX One begins to tell you why you'll be impressed.

Its tuning is refined, balanced, and remarkably transparent, allowing the quality of the driver to become the focal point of the listening experience.

Pros: 

Exceptional detail capture for a true wireless design
Superior imaging and instrument separation
High resolution third generation Myrinx driver
Balanced and mature tuning
Excellent vocal reproduction
Controlled and textured bass response
Extended but fatigue free highs
Superior quality metal acoustic cabinet construction
Comfortable fit for long listening sessions
Physical buttons offer reliable operation
aptX Adaptive and aptX Lossless support
Wireless charging support

Cons: 

ANC performance is good rather than best in class
Listeners seeking heavy bass emphasis may want more low frequency content
Utility app functionality is relatively simple compared to larger brands
