my 3 (or 4 year old) CX-300's died today - Or at least the cable in the left ear peice has finally broke and I cant really just squeeze or bend the cables together and use a little sticky tape to prolong their suffering. but then again after 3 or 4 years of double kick drums, heavy metal drop tuning riffage and mindblowing jizz worthy guitar solos its fair to say that they deserve to be retired. Are there any worthy headphones for around the same price that offer roughly the same sound or slightly better?? I dont want to go too overboard with the budget so lets say I have around $50 or less. what would be a worthy replacement?
