Doesn't work with Poweramp. They have the best equalizer I've found on Android and it's unusable with my Jabras without distorting the audio, so I'm forced to play music through the Amazon music app, which has a terrible UI. If I had known this was going to be an issue I would've purchased different earbuds. Update: Audio has been inconsistent for a while now. Max volume decreased a lot. Now my right earbud doesn't put out any audio. I'll be staying away from Jabra in the future.
