I am looking around to buy the most durable and tough pair of headphones that will work with both my mac and my ipod touch third gen ipod touch. In the past two years I have gone through about fifteen pairs of headphones, both cheap and mid range, and expensive. All of them have not worked for more than about three months. Do any of your guys on this forum know of a brand of headphones or something that will last for a long time or has a lifetime warranty on it or something? I am looking for something with the price range up to 80 dollars and down.
