The model I own is a Sharkk Bravo (a rebranded Verisonix N100B). The specs may suck but to my ears it has a quality of spaciousness, definition and realism that I've heard in few (if any) other headphones.
I use it not for music but for television, DVD, Blu-Rays and such. Music I almost exclusively listen with loudspeakers. The only headphones I use for music are with my portable digital audio player (Sandisk Sansa Clip Zip with RockBox software). They're KZ ATE in-ear monitors, which I bought dirt cheap ($15 or so) and have such a balanced sound that I still prefer them over much more expensive KZ models I own (like the stunning sounding AS-16).
