Check out the Sennheiser HD 202! they're around 30 bucks last time I checked and great fidelity and durability for the price.
edit: ok ok sorry you're right, $15 > $30 "heck, it's even twice as much!" i guess my point is that there are things that won't break the bank that sound way better than you'd expect, that's all. :)
edit2: Oh, and i _ALSO_ frequently break or lose mine, that's why I don't like spending more than the 30 bucks. ;)
