So my left earbud decided to die on me on vacation last week. Back at home now, I need new headphones. I would like to take a step up from the standard apple headphones, but seeing as I am a relatively broke college student, I don't have several hundred dollars to spend on some awesome headphones. What would you suggest in the $50-$100 range? I might be able to go a little higher for a great deal. What do you guys suggest?
