I got my new QC35 II headphones a week ago. My main interest is in listening to music while walking outdoors. I have ripped a few CDs to my PC (Win10, Windows Media Player, MP3) and copied the files further to my fairly new smartphone (Samsung Galaxy S20 5G, Android 11). App software is supposed to be the latest, 4.8.1, date of headset manufacture was 15 September 2020.
Problem 1: When double-pressing the multi-function button (supposed to be "skip forward") the music stops and the pointer returns to the beginning of the song, i.e. same outcome which is specified and happens for the triple-pressing ("skip backward").
Problem 2: I really thought and hoped that the "skip forward" would mean jumping to the next song, but it might just mean jumping to the end of the ongoing song??? (Which is not happening either, as explained.)
The latter problem could partly be overcome if there was a way to rip/copy the string of songs into a single file. Unfortunately the fast-forward function is tediously slow. Not a good solution.
If the correct function of "skip forward" is to start the next music file in the same folder, there is a serious error in my headset (HW or SW) which I certainly want to have rectified. If, instead, the "proper" functioning was just jumping to the end of the song, my very strong recommendation would be that an app software update would make it to jump to the next song.
