Recommendations for headphones under $400?


Pretty simple
Good recommendation for a pair of headphones under $400, these could be lightly used so new prices are not the limit.
Mostly listen to rock music so must have a fair bass response
Presently using an old pair of Grado that are really not that comfortable to wear at all, and do not have decent bass.

Thank you

Good questions!
Wired for sure, will be used in a couple different systems
One is an old Linn Classik all in one with built in headphone output
Another will be from a Schiit Magni 2.
Mr Speaker's Mad Dog's. Nice rich sound. Probably not as accurate as my up market Senn's but very enjoyable.
