KEFINE Quatio Hybrid IEM – Precision-Tuned Versatility, Now in 2DD+2BA Hybrid Format
Discover KEFINE’s first hybrid IEM – the Quatio, a premium 2DD+2BA configuration built to deliver a rich, immersive, and musical listening experience. Designed for audiophiles seeking both technical finesse and tuning flexibility, the Quatio features a quad-driver architecture with two dynamic drivers (10mm DLC + 8mm PU+LCP) and dual balanced armatures, delivering exceptional clarity, impactful bass, and refined highs.
What sets the KEFINE Quatio apart is its dual-way crossover system—a combination of physical acoustic channels and electronic crossover boards, ensuring each driver is precisely tuned for optimal performance. Whether you're enjoying jazz, classical, EDM, or vocal-centric tracks, the three interchangeable tuning nozzles (Warm, Balanced, and Neutral) allow you to tailor the sound to your preference.
Housed in CNC-machined aluminium alloy shells, the Quatio combines sleek aesthetics with superb ergonomics. Each shell is polished, anodised, and crafted with ultra-fine tolerance (0.01mm) for a snug, fatigue-free fit.
Bundled with a high-purity silver-plated copper cable, this IEM also features a modular plug system that supports both 3.5mm single-ended and 4.4mm balanced outputs—perfect for pairing with portable DACs and players.

Let customers speak for us
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.
I’m really impressed with the Hiby R1 — such a compact device, yet it delivers powerhouse performance. The raw specs on a spreadsheet don’t capture the real experience. Once you pair it with Type‑C IEMs and play FLAC files, the sound quality speaks for itself: clean, detailed, and surprisingly dynamic for something so portable. It’s proof that great audio isn’t just about numbers, but about how the gear actually performs in your hands (and ears).
It was neatly packed and unexpected case has been delivered along with the DAC. Had a nice experience too with the product. Loved it!
I've previously owned some budget iems like kz zex, tangzu wan'er and chu 2 but Ohh boy the sounds on STA HI-END is so soothing and melodious and it handles eq like a champ so no complaints from there too. Absolutely go for it you won't regret
Powerful, clear and you can hear the complete trace of audio.
I have been using the Tanchjim Bunny DSP for a while, and for the price, it’s honestly a very good set of earphones. The build quality is very simple but good, and the light weight makes it very comfortable for long usage.
The sound quality is very balanced for the price. The bass is good and controlled rather than overemphasized, and the mids are good so that the vocals are very natural, and the trebles are good and detailed but not harsh. This makes them very good for all types of music.
The Tanchjim Bunny DSP is a very good earphone for the price, and I would recommend it for people who are looking for a very simple plug-and-play earphone with good sound quality.
Sound is very good and accurate.. Soundstage is also wide and deep.. Like this Bunny...
Overall good quality
WelI i loved the iem Its good for my studyinh and music session go for it iems
Bets budget dac that gives you clear mids and more treble extension... If you are into edm trance symphony orchestra style music... then you will hear better instrument separation...
The cable is soft material so not for on the go will wear and tear... If you are musichead and always hooked then better go with audiocular beam it has cavlar braided cable for good rough n tough life space
Heard a lot of stuff on internet about this dac like hitching or buzzing sound and was bit nervous , but after purchasing I haven't faced any problem with it and I'm fully satisfied with the build and sound quality of the product.
This is one of the best case I have used till today. Definitely beats other cases at this price range. It is much better than the generic cases available on Amazon, Flipkart, etc.
I have recommended this case to my friends who were so impressed on seeing it.
Why?
The quality of music that it is deliveing is Awesome . I was not sure if it is worth investing before buying. But after I tested it , it was phenomenal .
Also I would like to thank The Audio Store , they packaged this box so nicely , it has 4 to 5 level of protection, Also I was not expecting the case , it is cherry on the cake, I was bored of that low quality cases.
Thank You The Audio Store
You're the best
