Actually, l'm new to this IEM world. Such an amazing product. If you are new to iem just as me, I would highly recommend his product to try out. The OG. There are 16 types of tuning options to play around and explore your favourite music in a new way and the build quality is also pretty good. Overall a nice product 👍.

Good sound

5/5 Mids and Highs
5/5 Well balanced Bass, doesn't overpower the music
5/5 Design look premium and classy
They are quiet heavy and huge

Good

They sound just amazing, I would say that the app a little rough to use. I can vouch they sound amazing. better than most of the tws which are out there in the market. Also, the Online dsp, gives a little edge it you want to tune them, and you can also upload your on DSP. Overall at this price point, It' a 10 on 10 deal.

This is a compact amp that has a clear sound output which can be described as slightly warm. Vocals are clear and midst nice. Works straight out of the box. Balanced xlr input is a big plus. Overall it is good value for the price. Will recommend it to everyone

Really a great product for the price offered using thebuds for the first time and it has exceeded my expectations. The sound is more balancednot a thumping bass but withclear vocals, treble and and a surrounding bass. Also there's someissue in connectivity which I faced at firstbut saw a tutorialon resolving the issue online.

everything is great but would have been even better if it had a mic

Awesome case, providing safety

It’s simply great upgrade from KZ. best output at best price

Had received in a day itself and it’s all that I had expected and more.

Very good sound and bass . Clear vocal and instruments

Fosi GR70 is an efficient amp and works well as a preamp as well as a headphone amp. It drives my hd600 excellently.

Amazing quality
Ordered 5 units and all were awesome
Thank you so much

Great part is that it got delivered very next day

I’m genuinely impressed. The sound quality is exceptional—crisp highs, clear mids, and a bass response that’s just right. It doesn’t overpower the mids or muddy the overall sound, which is a rare balance to strike in this price range.

🎧 Sound Signature: Tuned to the Harman Target with a tasteful bass boost. It adds warmth without sacrificing clarity, making it perfect for everything from vocals to electronic music.

🔊 Bass: Not too high, not too low—just enough to give depth without distortion. It complements the mids beautifully.

🛠️ Build Quality: Solid and premium-feeling. The fit is comfortable for long sessions, and the mic is a handy addition for calls or gaming.

Overall, it’s a fantastic value for the price. If you’re looking for an IEM that delivers refined audio with a touch of bass and excellent build quality, this one’s a winner.
