[NJ Hero]

Hi, I'm looking for headphones for my boss. I've bought my headphones with the help of this forum in the past and I'm looking for the same help again. He enjoys Pink Floyd, Led Zepplin, Rolling Stones, Metallica, and Guns and Roses. His budget is around $120-$200.

Do they need to isolate noise (basically open or closed back?)
 
Many people LOVE Grados for rock, but I've never owned a pair.
 
If I were to recommend something I've owned for his tastes, I'd tell him to buy an Audio Technica ESW9 (or ESW9a). They're great for rock; nice bass, forward mids, and non-fatiguing treble, they're very comfortable for an on-ear headphone, and they look great. 
 
Here are some on Amazon. The first pair is under $200 shipped!

Yes, those are wood cups.
