Sound issue in right ear

Hi!

So I’ve ruled out the fact that it could be the cable and or the TR device as I’ve tested it on a mobile device as well as my PC whether it be direct or through the mixamp. I know it’s 100% the headset as if I wiggle around the right ear cup and slide it up and down to get to a certain spot the sound will start playing but as soon as I move it a tiny bit it will distort and or stop. I was wondering what the issue could be and if it was possible for a rookie like myself to repair it as I don’t want to buy a new headset, thanks :)

@oldturkey03 one of the screws was too threaded to the point I had to pry it open but this is what the insides look like. I hope these pictures are good enough
