Headphone Recommendations

Requesting input from all you headphone lovers out there. I have a friend whos looking to buy some good quality headphones. Around $250 new or used is his budget and would prefer to buy new. He needs a closed over the ear style, just cant stand buds. They will be used at work mostly listening through Media Slayer, therefore a very transparent top end wouldnt be needed. Headphones with good bass is what he would prefer, his music preferences reflect that. Lots of classic rock and alternative, Floyd, Tool, etc. He has no interest in an amp or DAC at this point(he wants to save his pennies for a two channel rig) so please keep that in mind with recommendations. Any suggestions or opinions would be appreciated. thanks in advance, Justin.
