First post here
I’m experiencing that on some tracks the volume goes up in quiet passages of the music, and down in loud passages with a lot of bass. The song that reveals it the best to me is Lost Frequencies - Are You with Me (Gianni Kosta Radio Edit).
It is quite annoying on this track.
I have been in contact with Anker Support who sent me a replacement unit, which does the same.
Does anyone else have this issues?
