Most of my music is rock. Everything from classic to punk to progressive, but a focus on alt. rock. Some classical music as well. Bout 50/50 on male and female vocals.   I am a big fan of the Sennheiser sound, so no complaints there, besides their lack of isolation.   My amp is the Objective2.

I am currently looking for a good closed headphone around the $300 ($350 MAX) range. I am considering the Denon AH-D600 because I can get them for $200 new through my employer. I am anxious because I don't seem them on any recommendation lists.   Are they bad pair of headphones? Or just bad...
