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 the "clean, detailed sound" and "excellent clarity" with strong vocal separation. Many noted it's "best in this budget" with controlled bass, though some found treble fatiguing. Not ideal for bassheads. Several mentioned it works well without a DAC. A few customers felt it didn't differ much from standard earbuds.
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
i sent these messages to my friend in real time when i was trying out the kefine klean sv in real time
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.
BUDGET ENDGAME IEM.
SILVER NOZZLES-GOOD,BLACK-BEST FOR MOST PEOPLE,GOLD-FOR SPECIFIC PEOPLE,
BEST UPGRADE FROM 20$IEMS
Best clean sound at this price point
Excellent
Used kz zst x for 3 years and I wanted to buy a more technical iem but this is not that analytical in my preference, and also feeling fatigue with the treble so if you are new to iems then probably try other before buying this
Need to be used and I will give long terms review
All round decent
Perfect
Warm, detailed, wide soundstage. Less bass
This is my first set of IEMs. The overall sound signature feels quite flat with no particular emphasis on either bass or treble. It's not overly bright either. Good option at this price point.
Best in this segment
excellent iem
Pretty fantastic overall. I was previously using Tws form nothing (nothing earbuds 2). I have to say detailing is more better in these Iems. I can hear every instrument clearly. Vocals are pretty clear as well. Have used them in Valorant as Ascendant 3 player and have to say they sound pretty good. But I am more used to the sound signature of hyperx cloud 2 which are my daily driver in gaming. I have used these in valorant and must say they sound different than cloud 2. I have ordered a dac I will be using to test gaming with these Iems. I will update after that dac arrives.
Really Good built. Clean audio (as the name suggests) I don't prefer as much Bass as most people so pretty much the best version I could have bought in this range. Vocals feel rich and overall a very balanced experience.
Amazing sound quality

It feel like music stunning
Thank you Audio Store for the free gift. I am elated.
I am extremely satisfied with EarAudio 4.4 mm Male to 3.5 mm female adapter cable. The quality of the product is top notch and well made. I am now able to use my 3.5 mm cable with my iems plugged to my dac. Recommended!
It's a good headphone under this budget and leads give me a reliable delivery products as I satisfied from audio stores and if I buy remote sound products I will buy from audio stores and the very good very product in the budget 1200 rupees it's a good like premium and classic IEM IN EAR MONITOR.
Great sound quality with best in class clarity in beats and sounds.
Great bass texture, vocals and mids are clear and sound good, it has good details and sounds clean overall. Takes eq well. Major step up from wireless earbuds in sound quality. Product got delivered in 5 days dtdc, nicely packed. Cable and tips are not the best, forgiveable for the price tho.
Product is genuine but the main thing is the delivery time, it's awesome, they're really quick in this thing and also pretty genuine store.
My review is after 4 days of listening. The packaging and delivery was great. This is my first audiophile IEM with the latest planar driver tech. I own the Tangzu Waner SG and Kefine Klean as entry level IEMs.
Astralis IEM plays any genre of music flawlessly with fast transients, rich-textured bass, perfect vocals, smooth treble with a touch of airyness and sparkle which is non-fatiguing. As I am treble sensitive, these can be worn comfortably for longer duration.
Please note they might sound low in the beginning, the volume needs to be cranked up a bit as they require a tad bit amplification with the DAC. The included DAC is perfectly fine even if you don't own any other DAC. Works perfectly with phone or laptop; though using the DAC is recommended to get the full potential of this IEM.
Coming to the sound output with the DACs:
With the included DT01 Pro - More neutral presentation with soundstage which is mostly centre-staged.
With the Audiocular Note - Bass which has more punch + rumble and better energetic presentation with soundstage which is wider and has a better sense of openness.
Among the DACs, the Audiocular Note brings out the full potential of the Astralis.
Thanks again to The Audio Store for a great packaging and delivery experience.
This iem sounds very good.Good for music and gaming,i loved it and I'm satisfied for buying this.
Worth buying it.
The KZ Castor Pro is one of the best entry-level IEMs I've used in this price range. The sound quality is impressive, with clear vocals, detailed instruments, and punchy bass that doesn't overpower the mids. It offers excellent clarity, making every song enjoyable.
It's also a fantastic choice for beginners who want to experience audiophile-grade sound without spending a lot of money. Whether you're listening to music, watching movies, gaming, or enjoying podcasts, the audio feels clean and immersive.
The comfort is good for long listening sessions, and the build quality feels solid. If you pair it with a decent DAC, the sound becomes even better with improved detail and separation.
Overall, I highly recommend the KZ Castor Pro to anyone looking for an affordable entry-level IEM. It offers outstanding value for money and is a great starting point for anyone entering the audiophile hobby.
I can catch all the little details in songs with the hi-res audio. I chose these earphones to enhance my movie-watching experience, and they do the job. I watched a bunch of scenes from 'Dhurandhar: The Revenge' over and over, and these IEMs gave me a hell of an experience! It felt like I was watching this movie in a theatre for the first time.
Big thanks to The Audio Store for bringing these experiences to us!
Overall very Good product but value for money is High
Excellent IEMs for the price. The sound quality is clear and detailed, with great instrument separation and balanced tuning. They're also comfortable for long listening sessions. Definitely one of the best options in this 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.
