KEFINE Klean SV In-Ear Monitors (IEMs)
The KEFINE Klean SV is the evolved Silver Version of the highly acclaimed Klean series, engineered for listeners who crave speed, clarity, and precision. Featuring a new-generation 10mm DLC (Diamond-Like Carbon) diaphragm dynamic driver, the Klean SV delivers a faster, tighter, and more resolving sound than its predecessor—without sacrificing musicality.
Designed with a dual-cavity driver structure, the Klean SV ensures excellent consistency across bass, mids, and treble, creating a well-balanced yet immersive soundstage. Whether you’re a detail-loving audiophile or a daily music enthusiast, this IEM offers exceptional transparency and control across the frequency range.
One of the highlights of the Klean SV is its three interchangeable tuning nozzles, allowing you to fine-tune the sound signature to your preference:
-
Silver Nozzle – Balanced and natural
-
Gold Nozzle – Neutral, transparent, and highly detailed
-
Black Nozzle – Warm, smooth, and bass-forward
Built to last, the metallic alloy ear cavities are crafted using high-precision casting and polished for a premium silver finish. The ergonomic shell design follows the natural contours of the ear, ensuring long-term comfort and a secure fit.
KEFINE bundles the Klean SV with a high-quality silver-plated copper cable, featuring standard 0.78mm 2-pin detachable connectors. To suit different listening setups, the IEM is available in 3.5mm single-ended, 4.4mm balanced, and USB-C termination options, making it compatible with smartphones, DACs, DAPs, and desktop rigs alike.
If you’re looking for a high-resolution dynamic driver IEM with tuning flexibility and premium build quality, the KEFINE Klean SV is built to impress.

Customers praised these IEMs for "clean, detailed sound" with excellent vocal clarity and instrument separation. Many noted "great value for money" with premium build quality and three tuning nozzles. While most loved the balanced sound signature, some found treble fatiguing and bass lighter than expected. A few mentioned limited difference from standard earbuds or gaming audio concerns.
- The separation, details, highs-mids-lows, the bass just enough to make it delightful
- My mind is blown listening to the vocal clarity and instrument separation
- Premium design. The build quality feels excellent, everything looks genuinely premium
Absolute bomb! I am so happy with my purchase, these turned out to be way better than I expected. The separation, details, highs-mids-lows, the bass just enough to make it delightful.. Great value for money..
Worth buying it!!
I’ve been using it for the past two weeks, and it has performed amazingly well. I absolutely love the golden nozzles. Overall design is premium. The build quality of both the IEMs and the cable feels excellent, and everything looks and feels genuinely premium. Overall, I’m really impressed with the quality and experience so far.
As it's name suggests it's sound signature is safe and clean. Safe because it is kind of bright iem but it didn't gives you ear fatigue easily also imppresed by it build quality too . Overall a perfect product around its price range 😀
Delivery was on time, packing was nice. Product is well producted. Iems themselves are good and best in this budget range. But require specific frequency and players to get most our of them.
Clean, refined, and smooth audio! Absolutely a great product.
My first pair of IEM and I absolutely loved it🥰
I’ll recommend the audio store and purchase more in future
Worth every penny! This is not for bassheads as it lacks just a bit on the bass department, but the separation is awesome and the sound stage is also huge. Awesome for gaming as well! (Apex Legends, Arc Raiders, PUBG)
good. don't overthink about it this and that iem I you want clarity and details it's good and don't think about bass too much that feeling get when the situation unless no it's not like tws and that's it and don't think 3.5mm and c buy anything it's almost same
My mind is blown listening to the vocal clarity and instrument separation, and yeah I'm using it without a dac 🤯
Clean, detailed sound with good clarity.
Tight and controlled bass rather than overly boosted bass.
Forward vocals and clear mids. Very good iem
What a great great experience.
Update 1 month mic have hissing issues now while playing gaming my teammates is complaining about hissing noise coming from mic don't buy type c version cable has only 1 month warranty it's scam
For music it's good music feels like more alive it sounds clean as it's called it doesn't Excel at one thing just clean audio for everything
For gaming it's not good footsteps are clear but when enemies are above hard to pinpoint positional audio best nozzle for gaming is golden one still not comparable to CCA PHOENIX which is more gaming centric overall it's very good 2
Sound quality felt good with tight bass without rumble

These are my fourth pair of IEMs, and honestly, I can’t find a single fault with them. The sound signature is beautifully smooth, well‑tuned, and perfectly balanced. Vocals come through with striking clarity, making every track feel alive. Totally worth it — they deliver an experience that goes beyond expectations.

The AUDIOCULAR SPARK Hi-Res Portable DAC Dongle with CX31993 DAC and MAX Amp is a very impressive option for anyone looking to take their mobile audio experience to the next level. Despite its small and portable form factor, it delivers a significant improvement in sound quality compared with the standard audio output found on many smartphones, laptops, and other devices.
The first thing I noticed was the overall improvement in clarity and detail. Music sounds cleaner and more open, with better separation between vocals and instruments. Vocals have a good amount of presence and sound natural, while instruments are easier to distinguish, especially when listening to well-recorded tracks. The bass has good punch and control without overpowering the mids, and the treble provides a nice level of detail without becoming excessively sharp.
The CX31993 DAC does a great job of providing a clean
I’ve been using the AUDIOCULAR D07 CX31993 USB DAC & Amp for a while, and overall I’m quite impressed with what it offers for its size and price. The biggest advantage is its compact and slim design, which makes it very convenient to carry around and use with a laptop, PC, or compatible smartphone.
In terms of sound quality, the D07 provides a noticeable improvement over the built-in audio output of many laptops and phones. The sound feels cleaner and more detailed, with better clarity and separation between instruments. Vocals sound more natural, and there is a good amount of punch and control in the bass without making the overall sound too boomy. It also gives headphones and IEMs a little more power and makes music feel more engaging.
The CX31993-based DAC does a good job of delivering clean audio, and I particularly appreciate the plug-and-play functionality. There’s no complicated setup or additional software required in most cases, which makes it very easy to use. The small form factor is another major plus, especially if you want something portable rather than a bulky desktop DAC/amp.
For casual listening, streaming, gaming, and watching movies, it performs very well. Of course, it shouldn’t be compared with much more expensive dedicated DAC/amp systems, but within its price range, it offers an impressive combination of sound quality, portability, and convenience.
Overall, the AUDIOCULAR D07 CX31993 is a solid choice for anyone looking for an affordable USB DAC & Amp to improve their everyday listening experience. It’s compact, easy to use, and delivers clean and enjoyable sound. Definitely a worthwhile upgrade if you’re currently relying on basic built-in audio.

Loved it
It's actually good piece and getting better sound clarity but not must satisfied with bass even though I bought improved bass version
Comfortable fit. Good for extended listening. Details pop out and treble is clean.
Nice Product, The sound quality is poor when the iem is directly connected to phone but the sound quality is very high when it is connected. Fully satisfied.
Really happy with the Salnotes Zero 2. Sound is clear and bass is good without being too much. Vocals sound nice and the earphones are comfortable even after using them for a few hours. Build quality is also decent for the price. Overall, good IEM and worth the money
Damn good and buy foam tips
Wonderful IEMS. Punchy bass. Clear trebles.
Absolute bomb! I am so happy with my purchase, these turned out to be way better than I expected. The separation, details, highs-mids-lows, the bass just enough to make it delightful.. Great value for money..
KZ Duonic sounds really good, better than my expensive Samsung TWS. The instrument separation is amazing.
GK kunten is a great iem at this price, very good sound quality, has clarity and good sound stage. I previously listened music on my bluetooth tws but when i listened music in these iem's i am just amazed.
Worth buying it!!
