currently rocking these. the sony mdr-xb500. i honestly love these things because of how comfy they are. they look goofy as hell on my head, but they're just so pillowy soft. lol. these headphones are more geared towards music with heavy bass.
i usually just listen to hip hop/rap but i'll throw on some rock from time to time too.
the next pair of headphones that i plan to purchase are these guys,

the jaybird bluebird x. they're a wireless, bluetooth unit that's getting some pretty rave reviews. check out a review here --->
