Hi, So I'm a college student, who runs a lot at the gym, also I have a small hike to my classes everyday, so I listen to, on average about an hour - 2 hours of music on my iPhone per day. I would like to invest in some good QUALITY--like good sound quality headphones. I dont mind the ones I got free with the 3G, but they're kinda dying now, and I would like something that has a little bit of bass to it, if possible, haha. Basically, I want something that will last me a while [college student so can't keep making investments ], but also have a high quality of sound. Feel free to throw stuff out at varying price levels, no real set budget as of now. Thanks!!
