For me, the short answer is yes. I listen to rock and no other genre. The 2.2 moves me like no other headphone except the LCD 3.
Here's a point to ponder though. I would recommend you try the 500 with the jergpads by modulor. That's what I have and use them with the Mojo. It was quite a revelation for me since everything opened up on the 500 after the pads. I can go non-stop for 3 hours to have a great musical experience.
