So the pleather on my M50's headband is starting to flake off. I'm thinking about contacting AT to get a new one but I heard they are expensive and mine still has a perfectly good cushion. Any ideas for repairing it? Should I wrap it in something? Ideally I'd like to do that without ruining the audio-technica across the top. My scalp is starting to get irritated so I'm going to try to do something.
