I have a different issue. My headphones don't turn on at all. No faint light or anything. They also don't seem to charge. There is no red light turning on when I plug it in. I checked the USB board visually but it seems fine. Also the battery seems fine visually and I tried to unplug it for 20mim or so. Nothing changed. The flexcable connecting the USB board with the Mainboard in the right earspears looks a little suspicious. It looked like this already before I pulled it out. Maybe that's the issue? 🤔 I just don't know where to get the right one. I'm located in Germany. Does someone have an idea?
