Might want to take a look at the Mad Dog modded T50-RP's by MrSpeakers. Circumaural, comfy as hell, detachable cable, and the smooth sound makes it easy to listen to for long periods of time and at loud volumes. 90% of the music I listen to is metal, and it sounds perfect, IMO, Holographic and weighty, but smooth, but it's more a result of the MD's being really good all-rounders.
