So after some advice and a ton of research, I've attempted to narrow it down to these headphones (for classic rock, progressive metal and some electronic).
Sennheiser HD 558 or 598 - Was about to get the 598 but I read some threads saying they weren't well suited for metal and that the 558s bass was better.. I also already own a pair of Sennheiser IE80s so I thought I might try a different brand but there's no real necessity for that.
Beyerdynamic DT 770 or 880 - Thought these might be good but my ears are sensitive to treble which seems like it could be a problem.
Maybe something else? I've read good things about AKG's and I've read a thousand recommendations for Grados unfortunately their comfort is rated pretty low. Reading through the forums has managed to make me more indecisive
