Bose QC 35 II - microphone issues on Android only
Since yesterday, if I connect my Bose QC 35 II headphones to my OnePlus 6T, when the call starts, the microphone whistles and then the sound is extremely muffled and there is an annoying white noise in the background (almost as if there were some interference).
This problem was not there before, and most importantly, when I try to do the same thing from my Windows 10 PC, there is absolutely no problem and the sound is perfect.
I tried to connect another android smartphone and the problem is still there. So it's definitely a headphone issuee. I just can't figure out what the problem could be.
edit: I also noticed that (always and only on Android), since there is this problem, the microphone is extremely sensitive and amplifies all ambient sounds much more than before.
I also tried to reset the Bluetooth settings from the phone, but no results. Any ideas?
