I own the mdr xb-1000s and the bass extends REALLY deep, and the soundstage is very spacious, that is for a headphone with a closed design (open back). The highs, on these headphones, can be sometimes intrusive, however, on almost all well recorded songs, this is no problem. And I'm sure, if you have access to an equalizer, this problem can be fixed for all songs... The mids on these headphones are well executed, seeing that the song X-Rated by Excision (assuming you've heard this track) sounds the cleanest on these headphones compared to beats and skullcandies (though not necessarily compared to my tf-10s, which are $400 in-ear monitors, but that's a whole different story). So if I were you, and only listened to dubstep, I think this would be a perfect canidate for a bassy pair of headphones.
