Let customers speak for us
The device is good quality and it sounds really great. But it has two issues.
You cannot switch between L/R channels. It lowers both channels volume. The issue is mentioned on FiiO website.
It has LineOut function, where device is playing on max volume and you can use your computer volume bar, but it is so loud that even on the lowest set it is screaming, so you have to choose another option and adjust volume on FiiO device instead.
I wish I knew it before buying.

Great product, excellent service - got it in 2 days after ordering to Lithuania. Thanks guys!
Приобрёл Wiim Ultra и не пожалел!!! Красиво выглядит, лёгок в управлении. Музыкальные файлы с флешки-не проблема!
Tidal и Spotify работают без проблем.
Bleutooth как траслирует так и принемает поток.
Отличный звук!!!
Excellent sound quality and versatility, good amplification and easy streaming. Thanks to Premium HIFI for great offer and fast oder delivery.
very good, short shipping
Since I've moved from PC to laptop I had hard time with the sound. Both quality and volume. Fiio KA17 came as decent solution. It's really compact, easy to use and good priced. I found it a bit tricky to deal with setting on KA17, but as external audio source for headphones it shines. Sound is clear and distinctive. KA17 can drive even my Sennhieser HD598 headphones although I suppose full size earphones not the best choice for dongle. As to KZ IEM range performance is excellent.
Excellent service, good communication and fast shipping. Highly recommended seller. The RattleSnake speaker cable I bought is a very high-quality product which brings the best out of my speakers.
Excellent store and service.
The FiiO M23 is an excellent product for reasonable money.
Android 10, easy to use.
Works quickly ,interface does not lag.
The sound quality is excellent.
Highly recommend.
WiiM Amp очень интересный , поистине заслуживающий внимания усилитель ! ( учитывая цену)
