So I just went home today to discover that someone had been messing around with my HD598s and got an ink stain on the headband foam. It's bothering me so much I tried to remove the stain with alcohol, soap, vinegar, nail polish remover and everything else but I still can't get it off. I guess I'll have to let it go since I've tried everything I have at home already to no avail, but would you guys happen to know if Sennheiser sells a replacement headband foam/padding? Maybe I'll replace it next time for when the foam starts flattening out.
