app is not good, btr13 on its own is better. application reliability needs to be MUCH better then it currently is, it doesn't pair properly on the majority of mobile devices I have. On the few it does I wish the app was more intuitive, please take a note from Poweramp; that EQ is viciously in depth but easy for anyone to make their headphones sound the way they want without help, but is always better with community support. FiiO, do better, I know you can.

Terrible app. Prioritization of connection between Bluetooth and wired is so confusing/non-intuitive/non-responsive that I finally had to disable audio via Bluetooth just so I can control the device (BTR-5) when connected via USB. It refuses to allow EQ adjustments during wired connection and via Bluetooth, if you opt for LDAC (which, why wouldn't you use LDAC for vastly superior audio quality...). I recently purchased a Qudelix-5k and it worked flawlessly as expected right out of the gate.

Been using UTWS3 for over a year. 2 stars given for the initial setup which was easy. Has a ton of options that I found refreshing after using other Bluetooth devices with nothing like them. 3 stars missing because the app is 100% useless at the moment. I have tried several days and through several updates with no improvement. Can't go to settings and they say disconnected even when fully connected through BT. Wanted to revise my settings, but even unpairing won't work. Please address this.

Starting from Android 12, there have been some changes to Bluetooth that we cannot fix in UTWS3. Please use a lower version like Android 10.

What’s new

1. Enabled NAS support for the K17.
2. Added support for DISC
3. Fixed the channel balance bug on BTR3K.
4. Fixed the bug where presets could not be saved on JA11.
5. Miscellaneous improvements.
