Hardy headphones for a student?

I'm a very active person, and I listen to a lot of music. I have tunes playing whether I'm hiking, biking, or just working at my desk. The problem is I go through earbuds like crazy. I've replaced my standard Apple earbuds 3 times now, after the bass went out in each and they fell apart. I'm looking for headphones that sound nice, can handle being knocked around, but won't empty my meager wallet. Suggestions?
