Hello, I'm a university student and I was looking to get headphones to get before the Spring semester starts. I will be wearing them on the train and also while walking (which I have to do a lot of), so I need them to be the ear-bud kind, not the big over the ears ones. I currently use the Sony MDR-V6 and am loving it. What I need: - They have to be the small kind, - Something that doesn't pop out of the ears easily while walking and moving around, - Be able to pump out deeper than average bass without losing the mids and highs. (Yes, I REALLY like bass, but NOT the muddled/"cool" kind of bass) BIG pluses: - Cord as long as the ones that come with iPhones/iPads, - No tangling of cord, I listen to trance and progressive. A huge fan of Armin van Buuren's mixes, for example. Design-wise, I'm not quiet sure how to explain it, but I would prefer them to be something that fit into the curvature of my ears, or perhaps the kind that are supported by the back and top of the ears. I get ultra annoyed when the little iPhone ear-buds pop out or feel loose, this would be unacceptable with the ones I get. Thank you for your help!
