They're probably about a year old, I don't listen to music at ridiculous volumes and don't think I've even played out with this pair at all. Only the right ear, the left seems to be fine. It's only just started to be a problem and isn't so bad that I'm about to open them up or replace anything just yet. Just want to know if anyone else has had this problem and if so what you did about it and how much it cost you.
