回答“Why does the left side of the headphones work inconsistently? ANNOYING”In my case, I realised if I twisted my right earcup, the audio on the left will start appearing again. I ended up How do I open it up? and realised that if I pushed the white wire inside the headphones into the headband bit, the left side audio starts to work consistently again. So I super-glued that in place, put it back together and all seemed to work. I suspect the portion of the wire that bends when you fold the headphones had failed, and doing what I did forced the conductive material together and also forced another part of the wire to do the bending instead. Not a great solution, but it seems to do the job. This is actually my second pair of the same headphone, my first pair broke 9 months in so I claimed the warranty. The current pair started to fail in a similar amount of time.
回答“audiojack turn off the headphones?”I thought this was an intentional design to prevent damage to the bluetooth DAC if there’s a wired source plugged in. Am I wrong?
