So after having this same issue myself, I took apart the power switch, it consists of 4 small wires that push across multiple contacts, they seem to bend down over time, after bending them to be a bit taller again, all issues are fixed. It looks like two of them are for the right ear, which is why jiggling it around often fixed the issue temporarily. I didn't take any pictures of the pad unfortunately, but here is a picture of the switch part. Hope it helps someone
