sony MDRs are nice. they have good speaker disk, but mostly people buy them cause thee look sick. the MDR150,200, and300 are black, and the 300s are silver. they are almost identical, so dont pay the 50 bucks for the 300s, it isnt worth it. you can make the 150s fold up with a 2 second fix, and they are easy to take a part and spray paint silver. the MDRVJ series (500/700) are really nice. they are expensive, but are pretty cheap on ebay or www.ecost.com. they have big drivers, tons of bass, and are tough. the 5s are black, and are not as nice, and the 7s are the big silver ones you always see. howerver, Aiwa makes a 30 dollar headphone that is really nice. same low response as the 700, same high response as the 500, neomodium (sp) magnets, 40 mm drivers, and an external mute button. not as cool looking, but they sound just as good as the MDRVJ-700s off an mp3 player. they wont handle anywhere neer the power of the big sonys though, those things can be used as computer speakers. but check ecost if you want mdr 700s for 96 shipped. 56 or something for the 500s. dj headphones are the way to go, cause they really help keep your ears warm.
