It has bit of front lips too so the gestures won't be that smooth since the edges are bit raised and it also has strong magnets . Got it fromhere .

Old photo I found I took 6 years ago from a budget phone.

These are just my initial impressions; a full review will be coming soon.

This is colored jm1 target iem which has tasefully done Bass and Mids. It's the overall all rounder iem with no focus on one thing with good technicalities.

Bass:

Decent punch and rumble with good control. It's noticeably bassier than neutral sets, especially with Dunu Candy or KBEAR 07 tips.with eq you can pump a good amount of subbass.

Mids:

The mids are lush and slightly warm, giving vocals a fuller and richer presentation. Both vocals and instruments sound natural and engaging.

Treble:

The treble has Moderate energy and detail without being harsh. Wide-bore tips add extra sparkle but not really that much, while the overall tuning remains smooth enough for listeners sensitive to treble fatigue. This lacks air so these won't be really for pure treble heads.

Well during the upcoming goat sale both of these will be around 50k range, I am just getting confused about which one to buy, I would prefer OnePlus but I have heard that OnePlus service centres are shutting down and oppo will be the one providing it but I asked oppo service centre they said they havent started doing it, my question about vivo 200T is origin os, I have seen its not very polished any many features missing like app hiding also since I have out of loop on newer phones so idk much just help a guy out....

• Do note that the cable in the image is Audiocular c03 cable not the stock one

Build & Comfort

The Klean SV makes a very strong first impression. The all-metal shell feels compact, dense, and well-finished, but it never becomes bulky or awkward in the ear. The shape is easy to seat, the fit is stable, and comfort remains good even across longer sessions.

What stands out most is how complete the package feels for the price. The included case, cable (fairly good), tips, and especially the three tuning nozzles make it feel like Kefine is trying to offer a more serious product rather than just another cheap budget IEM. It is not flashy, but it feels thoughtfully put together.

The nozzles are made of steel alloy, so they won't oxidize, and they are very easy to swap, which is a nice touch for a budget set. The included tips are also of good quality, especially the KBear tips. The lip is 6.1 mm near the end of the nozzle so it faily comfortable

Nozzles

• Gold: Focuses on vocals and upper mids. It can be a little sharp for some listeners, especially on certain recordings. It gives the sound more presence and can make details in the upper mids more noticeable, but it is not the most forgiving tuning if you are sensitive to brightness.
• Silver: Provides a more neutral balance, offering a smoother and more forgiving listening experience across different genres and recordings.
• Black: Offers a warmer and more balanced sound, with a stronger focus on bass and midrange. It is the most versatile option for general listening and is likely to be the best choice for most people, especially if you prefer a more relaxed sound.

Sound

The overall sound signature of the Klean SV is clean and balanced, with a slight lean toward the brighter side. The tuning is not for bassheads, but it is not so bright that it becomes fatiguing for most listeners. One of the strong points of the Klean SV is its resolution and the way it handles vocals and midrange details.

The treble is energetic and airy, which gives the sound a sense of openness, but it can also be a bit much on certain tracks or with the wrong nozzle choice.

Do keep in mind that I am not a basshead, so my preferences will naturally show in this review, though I will try to remain as neutral as possible.

Bass

The bass is controlled more than it is generous. It has enough mid-bass punch to keep pop, rock, and general listening engaging, but it does not deliver the kind of deep sub-bass rumble that bassheads will want.

I particularly like how the Klean SV handles bass. The low end is tight and the decay is quick, so it almost reminds me of a BA-style bass presentation. The DLC driver in the Klean SV seems to prioritize control over slam, and even with EQ it never feels like a particularly hard-hitting set.

With the Black nozzle, bass feels the most balanced and musical. Silver and Gold keep the bass leaner, which improves perceived clarity but can make the overall signature feel less full. If you want thick slam or heavy rumble, this probably is not your set.

Personally, I preferred the Black and Gold nozzles the most.

Midrange

The midrange is one of the strengths of the Klean SV, especially if you enjoy clear vocals and good separation. Female vocals come through with good presence, and instruments like piano and acoustic guitar sound articulate and easy to follow. The presentation is more open than warm, so it favors clarity over richness.

I would especially like to emphasize how well it handles guitars. You can easily hear the pluck of guitar strings in most tracks, and it is very enjoyable to listen to guitar-focused music with the Klean SV.

The tradeoff is note weight. Male vocals and lower-mid instruments can sound a little thin, especially if you use the brighter nozzles. That does not make the mids bad, just more analytical and less lush than some listeners may prefer.

Treble

Treble is where the Klean SV will divide people. It is detailed, airy (a sense of openness and spaciousness), and energetic, but it can also become bright enough to cross into sharp or sibilant territory on the wrong recording.

Personally, I have not found it particularly harsh or sibilant, but that does not mean you won't.

The Silver nozzle is the most treble-forward, Gold can make upper vocals more intense, and Black is the most sensible choice if you want to keep the top end under control.

For my taste, the treble is best described as clean first and exciting second. It gives the impression of strong resolution and openness, both of which I personally enjoy.

Technical Performance

For a budget single-DD IEM, the Klean SV performs well technically. Detail retrieval (the ability to distinguish fine details in audio) is fair, separation is clean, and imaging (the ability to perceive the spatial location of sounds) is precise enough that busy tracks do not collapse into a blob. It also has good directionality, making it easier to hear where different instruments are positioned.

Soundstage is not huge, but it is not cramped either. It feels natural and reasonably open for the class.

What impresses me most is the sense of control. Transients (the initial attack of a sound) are fairly quick, layering is respectable, and the tuning gives the impression of more cleanliness than most budget sets around this price.

It is not a giant killer in every technical category, but it is competent enough that the tuning does most of the heavy lifting. The tuning gives it a sense of refinement beyond what its price might suggest, while the technical performance is solid enough that it never feels like a gimmick.

Gaming

The Klean SV works well for gaming, especially if you want positional clarity and cleaner directional cues. Footsteps and ambient details are easy to pick out, and the controlled bass prevents explosions from overpowering everything else.

If you look at the last picture(do take the numbers with a ton of salt ,as it is by no means a standard of measurement , just think of it as suggesion), I mentioned that the horizontal soundstage is fairly good, especially in the front 180 degrees compared to the 180 degrees behind you. I would not say the vertical soundstage is particularly strong, though. It is more of a 2D soundstage than a 3D one, but that is not necessarily a problem for gaming since most IEMs in this price range do not have convincing vertical staging anyway.

I mostly tested these with Valorant and CODM. Unfortunately, I could not test them with CS2 because I had recently uninstalled it.

The Klean SV handles the sound design of these games very well. It is not the most spacious-sounding IEM for immersion, but for competitive play it makes a lot of sense. If you prioritize awareness and separation over heavy impact, it is a practical choice.

Comparisons

Klean SV vs Original Klean

Compared with the original Klean, the Klean SV feels cleaner, brighter, and more versatile thanks to the extra nozzle option. The original Klean is generally the warmer, safer, and bassier listen, while the SV leans more toward clarity, air, and technical sharpness.

If you already own the original Klean, the SV is not an automatic upgrade. It is more of a side-grade with a different tuning direction.

If you are buying fresh, the Klean SV makes more sense if you want a more open and detailed sound, while the original Klean may still be the better option if you prefer a fuller and smoother presentation. The better nozzle in SV also is a plus.

Klean SV vs Dunu Titan X

The Titan X is the more V-shaped and fun-sounding set. It has noticeably more bass impact and a more energetic presentation, which makes it the more exciting listen at first.

The Klean SV is cleaner, more balanced, and feels a bit more refined overall. While the Titan X can occasionally become slightly harsh in the treble on certain tracks, the Klean SV generally sounds smoother and easier to listen to for longer sessions.Remember that is how i personally perceive.

Personally, I prefer the Klean SV. It may not be as immediately exciting as the Titan X, but its cleaner tuning and better overall balance make it the set I reach for more often.

Conclusion

The Kefine Klean SV is a well-built, comfortable, and genuinely interesting budget IEM. Its biggest strengths are the compact metal shell, the useful nozzle tuning system, and a clean sound that gives vocals and detail plenty of room to breathe.

Its main weakness is also clear: the tuning can be too bright for some listeners, and the bass is not especially satisfying if you want weight and rumble.

However, if you enjoy a cleaner, more energetic sound and want a budget IEM that feels more refined than its price suggests, the Klean SV is easy to recommend.

Share the iems which you have bought recently or planning to buy today or near future

Havent charged these in months and battery still going strong, not using much rgb is better...

Do anyone of of have these unused or know if some site has these need these.

For me its kefine klean sv, So nice seeimg so many iems, share pic with of yoir fav ones too!!

For Now it will be kefine Klean sv

Ok so just got these today, havent experimented a lot with different nozzel and ear tips so cant say much but

* technicalities is its strong point

* sound is clean you wont feel like someting is drowing something else (for black nozzel atleast)

* bass is there and quite fast (not like planar iems but fast). Sub bass is there for emotional support just enough that i quite like it

* treble is a bit sibilant if you put silver nozzel havent head gold one for now

* soundstage is not that wide (delci is better ) nothing impressive

* tldr nothing stands out but i think thats the beauty of these its i think of the best balanced iem in these price range, for me these is better than og klean, (these are not that less bassy than og ). These is just me after few minutes listening. I might make a more detailed review but there is already so many reviews so i think its redundant, you can ask questions for details and any test i might try so you can drop comments

What are your thoughts on these, they be claimimg wild things like like strong bass without it bleeding into mids with 13mm virbration unit(sus) + zenith driver

Someone did a review these here

#Your USB DAC on Android may NOT be bypassing the system mixer

Most of you probably already know this, but on Android, even when using an external USB DAC, your audio usually still goes through Android’s system audio stack/mixer by default.

This has been the case since around Android 6.0 and even before that .

That means:

• Android often resamples audio (commonly to 48kHz)

• System DSP/effects may still be applied

• You may not get true bit-perfect playback

• Your DAC isn’t always being used to its full potential

A lot of people assume plugging in a DAC automatically bypasses Android processing — it usually doesn’t.

#The Solution

Use apps that include their own USB audio driver and bypass Android’s default mixer/audio path.

#Good options:

• HiBy Music (Free)

Excellent for local FLAC files and includes a built-in TIDAL login for bit-perfect streaming.

• USB Audio Player PRO / UAPP (Paid)

Basically the gold standard for Android USB audio. Supports bit-perfect playback and direct USB DAC access.

#The Catch: Streaming apps

These apps do NOT automatically make the official apps like Apple Music lossless

###Apple Music

Apple Music generally does not bypass the Android mixer on its own.

UAPP has an experimental “System Audio” feature that attempts to route other apps through its driver, but results are inconsistent and usually do not provide true automatic sample-rate switching for Apple Music.

###TIDAL

To get proper bit-perfect playback, you need to log into your TIDAL account inside HiBy .

Using the official TIDAL app can still subject your audio to Android’s resampling/mixer.

###Spotify

They did support USB DAC but limit it to a sampling rate of 48Khz 16 bits. Good enough

for most uses.Idk about it now i havet used recently so idk but it used be a feature few years back.

#Why It Matters

This becomes more noticeable with:

• FLAC / lossless files

• TIDAL HiFi / Qobuz

• High-end IEMs or headphones

• External dongle DACs

For people spending money on DACs/IEMs and wondering why Android sometimes sounds "off" or different compared to PC playback — this is one of the biggest reasons.

##Quick Tips

• Local files:Both HiBy and UAPP work great for FLAC/DSD stored on your phone.

• TIDAL users:

Use TIDAL through UAPP or HiBy instead of the official app for best results.

• Apple Music users:

On most standard Android phones, your audio is likely still being resampled to 48kHz unless you use a customized Android implementation/DAP from brands like FiiO or iBasso.Moon drop phone also does the same thing.

Feel free to correct/add more info if you know more about Android audio internals.This what i understood from my time in audio journey

With a bit of PEQ, they can sound very smooth, not gonna lie. Since I mostly prefer a slightly neutral tuning, there’s still a bit to be desired out of the box, but they’re a good budget pair. For me, they’re better than the SG2 in terms of soundstage and not too warm (though it has bass not too much nit too little )and closer to the 7Hz Eula, though not on par with sets like the Zenith (of course lol) or Kefine Delci. As usual, take my words with a grain of salt.

PS: Use a QDC connector ,I recommend the QKZ T1. I personally don’t like QDC connectors, so I just use and store them carefully, but it’s better to get a good one since the Kunten doesn’t have a screwed-down QDC connector. And as you know from reviews, the build quality is kinda bad, as usual.

This my humble eq for kz kastor bass edition UUUU

config i made It as neutral as i thought i could make , i am no professional or very knowledgeable by any means

If you guys can like try it and share your thoughts , make it UDUU if you feel like there is too much bass.i have made a PEQ too but its difficult to share.
