Great experience but the equalizer is not very useful since it keeps resetting. For some reason the app keeps forgetting the custom equalizer settings (User 1, 2 and 3) after every few disconnects. If we could back up our EQ settings (to a local file for example) this problem could be made much easier to deal with. It is time-consuming (thus annoying) to have to re-do the EQ settings again and again and again. Please fix this FiiO or at least let us back up our settings. Edit: this is fixed now.

Hoped to use it control EQ on my Fiio K17 , which it doesn't do. I have been able to connect to the device and see the existing EQ profiles but I cannot edit custom profiles. I can edit one setting, but then cannot move on to another without exiting the profile. I have been using on my Samsung Galaxy Tab S9 Ultra and it's quite obviously not designed for a tablet screen but forcing it into phone mode, it's a still terribly designed app. It's now reverted back to Chinese so game over.

it has great options and makes music sound better. but now I can't even use the EQ anymore and itll crash the app. I had specific headphone tuning on and it doesnt bode well with my car. so I reset everything. literally and its broken. Update: went back to an older version and it works perfectly now. the new 3.43.7 update sucks and broke the best part of the app. Phone: Samsung S25 Ultra. Device: BTR15
