My friend is in the business for a new pair of portable headphones in the $100-$150 price range after his Skullcandy G.I.'s finally broke on him. He's looking for something with good mids and bass. The bass, specifically, from drum solos in songs. He listens to quite a bit of metal and (hard) rock. Specific bands would be Metallica, AC/DC, Slipknot, Korn, and surprisingly Queen and a little bit of Skrillex.
Hit me with all you've got, head-fi. The one caveat is he'd prefer to be able to go into a store and buy it, so it'd have to be from Best Buy, Guitar Center, etc.
