Alright, you've probably been asked this a thousand times before but I'm looking for some good headphones under $50. I'm a poor college student and I'm going to be using them while I walk to and from school and local stores. My collection is mostly rock/metal and piano pieces (not sure why) though I toss a bit of everything in my Zune.
I'm not quite sure what qualifies as a "good" pair of headphones so I thought I'd drop this question in while I scoured the rest of the forums. Thanks for reading.
