    Trying to adjust volume with headphones' volume control always turns volume down even when pressing volume up button. Volume control with these headphones works properly on Sony Xperia Z2 (Android 6.0.1) and Xperia Z5 Compact (Android 7.1.1). Problem only seems to occur on OnePlus 6 and ONLY when adjusting media volume, the controls work properly when adjusting call volume so should be fixable. Also, the controls worked for media too, for a while after some update but seem to be broken again.

    I already did and the response, after a few weeks, was

    "I am sorry that AKG N20U is not compatible with OP device. Please change to other headphone to check if issue still persists."

    Which imho is total BS.

    I have seen issues between AKG and OnePlus, but this is on another level :eek:

    Yeah, that is really weird. And the weirdest part is that at some stage the headset worked properly as described in Android documentation, chapter "Headset Expected Behavior" (https://source.android.com/devices/accessories/headset/expected-behavior) but then stopped working after a while. The headset alson works properly with other Android phones...
