I don’t know what happened but recently Bluetooth audio on iOS became so poor. It got to the point where I can’t have even a single song without audio breaking or distorting. I’ve tried brand-new Bose QC 35, cheap CMF buds, the degradation is noticeable both on my previous iPhone XS and current 15. It doesn’t matter whether the phone is far or close.
It’s so, so bad and I’m annoyed. I used to have absolutely no issues with my previous pair of QC 35. Could it be something with Bluetooth 5?
