I second the Meze 99 suggestion, at least if closed backs are preferred. If open or semi-open are acceptable, then I would suggest a look at HifiMan 4xx (or 400 series) and the Dekoni Blue's (Fostex T50's with better pads) both are great sounding headphones, the latter being darker sounding.
The problem with open is the leak sound when I use it in the office. I don't want to disturb the others with the sound of my music. xD
