I think these are good enough for this price. Extremely comfortable and yes they sound good.
I use IE300 for gaming and casual listening.

For comparison:

IEM: Tangzu Red Lion

DACs: JM12 (flashed with JA11 v2.2) & Audiocular Spark

Devices: ipad A16 & iqoo z7p

I got my Audiocular Spark back from a friend a few days ago. She mentioned that it sounded much better than a regular Type-C.

As I mentioned in an earlier post, I wasn't getting consistent sound quality between iOS and Android with the JM12. After flashing it with JA11 v2.2, changing the profile, and enabling PEQ, Android sounded noticeably better, while iOS also gained better bass than before.

However, with the Audiocular Spark, the experience is the opposite. On Android, the sound is significantly louder, fuller, and better overall. On the iPad, it sounds almost like a basic Type-C dongle with lower volume and less impact.

I asked my friend what device she was using, and she was using Spotify on Android. Neither of us tested the Spark with Apple's official dongle, as we both use an iPhone 13 as our daily device.

Has anyone experienced similar behavior with the Spark on iOS vs. Android? Could this be a compatibility issue, or is there something else I'm missing? Thanks!

Do you guys actually use all the eartips ??

I have kz caster and jm12 dac

My oiginal ear tip broke and looking for new eartip of medium size.

Also i want to get iem case which from again headphonezone ( image included ).

So before i get the eartip set i want to know long term review of the peop who had used it may be a month or more then a year

OoopusX is a rather new audiophile brand and their second release is the Op.22. After hearing some hype for this IEM, I was quite eager to try this out and see how it stacks up to other sub 5000INR sets. This unit was graciously provided to me for a week by u/Josephhri. You can check out his channel here!

Disclaimer: A big thanks to Shenzhen Audio for originally providing this review unit. Thoughts and opinions are my own and I was not restricted or instructed to say particular things about this set.

Subjective Preferences, Sources and Tracks

I currently own the Ziigaat Lush and Truthear Hexa and these serve as my benchmarks. The TRN Black Pearl was used as the DAC/Amp for most of my testing. I typically prefer balanced sets that are tuned to the JM-1 target; a little bass or treble boost doesn’t hurt though.

Most of my library consists of rock with some jazz, metal, pop and orchestra sprinkled about. If your library is filled with EDM, rap or hip-hop, then your conclusion might be very different from mine.

Build, Fit & Accessories

The Op.22 features a lightweight, plastic shell with decent build quality for the asking price of 3500 INR. I quite like the cyberpunk aesthetic and it stands out amongst its competitors. There is no semicustom shape to the inside of the shell and the nozzle is quite short and narrow. This may lead to better comfort for people with smaller ears, but I had to use eartips one size larger to create an effective seal.

The cable behaves quite well although it is unfortunately QDC and has no chin slider. I did not find it exceptionally comfortable with the QDC connector digging into my left ear. This could be rectified easily by forming the earhooks with a heat gun. The tuning mode dial feels solid and is quite satisfying to turn. I did not receive the full outer packaging but it is quite minimal. Enough waffling about the accessories, let's move on to the sound!

Sound

Bass

With the default tuning, the first thing you notice is the wonderful separation and imaging. In busy tracks like Tool’s Pneuma or Rush’s The Spirit of Radio, the bass guitars, kick drums and toms remain well distinguished with good body and timbre. The bass texture is lacking some crispness but this can be remedied to some extent with tip rolling. On Daft Punk’s Get Lucky, I turn the dial to add more rumble and slam while retaining mostly clear vocals. I found it easy and rewarding to switch between the tunings for every track or even sections of a single track. On Mountains by Hans Zimmer, I am able to savour the low percussion impact by turning the dial before the crescendo. The Op.22 demonstrates flexible and well-rounded lows that will satisfy nearly everyone but the extreme bassheads.

Mids

After my usual assortment of tracks, I did not have much to note down, because this set rarely places a misstep. The wonderful jazz album Clear Day by singer Emilie-Claire Barlow, in particular the cover of Coldplay’s Fix You, is the perfect album to test out the mids. From the thick bass to the light piano to the rich vocals, the Op.22 showcases brilliant timbre and tonality. As the track gets busier, every instrument of the Metropole Orkest remains well separated and imaged. Vocals are presented and layered extremely well without being pushed too forward.

Although some may prefer the relaxed upper mids, I was left wanting a bit more air and extension around 2kHZ for female vocalists with a higher octave range Adele or Celine Dion. For male vocals and guitar heavy tracks I would’ve preferred some more body from the lower mids around 500Hz. There are minor nitpicks that can be ironed with a handful of parametric EQ filters. OoopusX has settled for once and for all that excellent mids can be achieved on the tightest of budgets!

Treble

Overall, the treble is quite smooth and never falters into sibilance or shout. The upper treble and air in particular is well tamed. Violins and horns sound excellent with wonderful timbre. This set is fatigue free for long sessions and despite this quality, it does not lack resolution or detail. The intro to Saagara Shayana Vibho (A Prelude) by Agam has well mastered bird sounds that are staged accurately. Not many IEMs set themselves apart so well at this affordable price point.

However, all is not smooth sailing for the Op.22. There is a notable plateau in the lower and mid treble from about 3 to 7kHz. Transients of cymbal and drum hits are a bit harsh and unnatural. This is my only major gripe with this set but can be remedied with EQ again. It is still much better through the highs than plenty of other IEMs available.

Tuning Dial

The difference between the two dial positions is stark and it is easy to swap between them on the fly. One does not need to fiddle about with tiny switches, screws or nozzles to change the entire mood. With the dial turned to the bass mode, the mid bass packs an impactful punch. There is some bleed and muddiness but it is a worthwhile sacrifice to make for the few tracks that demand it.

Eartips

OoopusX provides two sets of eartips – regular silicone eartips and sticky Penon Liqueur-like tips. The regular silicone tips do not seal well for me and the bass is noticeable lighter and treble was smoother. The tackier tips sacrifice treble smoothness for excellent bass quantity and a tight seal. KBear Coffee tips with their wide bore and flange fit quite well with this set. The bass quality and texture improve noticeably and the Coffee remains my preferred tip on yet another IEM.

Comparisons

Kefine Klean SV

The Klean SV is the new and improved version of the Klean but it still doesn’t compete with the ooopusX. The Op.22 has better mids and smoother upper treble but has the same mid treble lift that plagues the SV, albeit to a lesser extent. Vocals have more energy on the Kefine but timbre is worse. Perceived technicalities are simply superior on the Op.22. The Klean SV is the better pick if you want a more V-shaped and dynamic tuning.

Tangzu Yu Xuan Ji

The Yu Xuan Ji is an underrated release from Tangzu that was a standout offering for its excellent stage, imaging and resolution. Compared to the Op.22 however, the forward Tangzu upper mids makes it sound thin, honky and shouty. The bass quantity is elevated on the YXJ and it retains excellent bass texture with the right tips. Through the lower and mid treble, the YXJ is simply smoother to my ears. It has a notable 8kHz peak and plenty of air but remains smooth to my ears. Perceived technicalities are excellent but the Op.22 matches it and surpasses the YXJ on tonality and timbre.

Truthear Hexa

The Op.22 comes incredibly close to matching what the Hexa offers for over twice the price. The lack of refinement in the lower treble unfortunately means that it falls a bit short to my ears. The Hexa offers more rumble and excellent bass texture. It presents vocals with a touch more intensity and air and remains smoother till the 8kHz resonance peak. For some, the Hexa may sound much brighter but for my I entirely prefer it. The stunning staging, imaging and separation on busy tracks is where the Hexa continues to display its crown as the budget neutral king.

Verdict

The Op.22 is now my default recommendation for those looking for a neutral, JM-1 tuned set even at twice it’s asking price. With just their second release, ooopusX have managed to offer a refined and mature set with class-leading tonality, timbre and technicalities. The tuning dial appears gimmicky just like the swappable nozzles or poor DSP implementations of competitors, but it is functional and offers a meaningful change. I am eager to see what ooopusX crafts next, particularly if they can continue refining their sound, accessories and material quality.

Who should buy it? Those who want a mature, neutral JM-1 tuning, an affordable platform for easy parametric EQ or a fun physical bass boost.

Who should not buy it? Those who prefer V-shaped tunings and gob loads of bass as well as those who can’t deal with elevated mid treble and QDC.

Hey everyone,

A bit of background: I bought a pair of BLON BL-03 back in 2022/2023, and I’m pretty sure they’re the original version, not the newer release.

They’ve been great for the price, and I really enjoyed using them. I’m planning to upgrade soon, but I’d still like to keep these working for sentimental reasons.

The problem is the stock cable. The quality wasn’t great, and it finally gave up—now only the left side works.

I think these use a slightly unusual connector (something with covered connector like in pic), so I’ve had trouble finding a compatible replacement cable.

Can anyone help me identify the connector type? Also, if you have any replacement cable recommendations for the BL-03, I’d really appreciate it.

P.S. I checked with Headphone Zone, and they told me the original BLON BL-03 stock cable (and any direct replacement) is no longer available. According to them, only the newer BLON BL-03 versions are compatible with the replacement cables currently on the market, while the original version isn’t.

Thanks!

So the thing is I don't care about type c or shi and as from my playlist can you suggest me btw these two and if I will buy bunny then I will go dsp and if I get truthhear gate I will later pair it with fiio btr11 and btw i like 3d and something that will last at least 1.5 years btw I will take care of it and since I'm a 15 year old I don't know much about this so please help audiophile 🫵
