I have a really thick 3.5mm audio in cable really great quality thats never going to break. The problem is the ends are two big to fit into the audio in hole. Don't want to use an adapter and compromise sound quality. What I was thinking of doing is modify the size of the hole by cutting off a part of the plastic. Would cutting the headphones up affect sound quality in anyway. I'm assuming it wouldn't be a problem as long as I don't cut into the drivers inside. The whole is right on the outside of the phones. Thanks!
