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 King!
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).

Excellent Value with Balanced Tuning
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.

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

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.
