08-08-2025It's not for me. I have the Fiio BTR5 and I felt it was redundant for the purpose I wanted it for. The WiFi signal cut out frequently, and the Bluetooth didn't have a great range. It's very nice, but it was very expensive. The equalizer didn't deliver rich bass.

08-08-2025Sound through IEM's and build quality is amazing, but a couple of notes;- FIIO player app has problems with .flac files. It will not play them in track order when listening to an album. This is a known bug since 2022 that the engineers have yet to fix. I installed POWERAMP (an $8 app) for my .flac files. You can use Poweramp for all your files if you wish, but just be aware of the limitation of the FIIO app- Product description mentions the retro cassette tape case is included. It is not. There is an, already installed, TPU case that matches the color of the DAP, but it is pretty cheap feeling.This is a 5 star DAP, but with the two issues noted above, I had to remove at least one star.
