It really vairies to be honest.
The headphones I use daily are KRK KNS8400 closed back headphones, however their initial purpose was for monitoring sound during filming sessions, but their neutral range is pretty nice on the ears. (As well as the fact I could wear them for hours without getting aches from weight)
Only problem is, because they are closed back it kinda cuts out all of the sound outside of the headphones so I sometimes end up shouting to people over skype without even realising it XD.
