Static in left ear
The speakers in both ears largely work as expected, but in the left ear there is a (rather low volume but still very noticeable) constant static sound whenever any sound is played. It is not just a by-product of noise-cancelling, as the static is there both with noise-cancelling disabled and enabled. What might be the cause of this, and is there any hope of fixing it?
