Function problems
Problem
Solution
I can't control music functions
on my device.
Make sure the Bluetooth audio source supports audio video
remote control profile (AVRCP). Some music or video player
apps don't support AVRCP. Check other apps to see if the
problem still exists. If so, try to reconnect the earbuds.

noise cancellation feature?

cancelling control function is assigned to your earbuds.

You can switch between these three modes in the
following ways:
