I just purchased a pair of Soundcore Life Q20 headphones and when noise cancelation is turned on, the volume on more"complex" songs fluctuates very noticeably.
As an example, when I play Billy Taken - Devil On My Shoulder, the fluctuations are extreme.
It is far less noticeable on easier, more homogenous songs like most pop or hiphop songs, but the Billy Talent songs and many other rock songs show this behavior.
It disappears when I turn off NC.
Does anybody know a solution? I contacted support but so far only got one of those prewritten standard replies.
