AKG K270 Playback is a great choice if you already like the Sextett-style vintage AKG sound, just make sure you don't get the way more common K270 Studio (K270P has silver trim rings like the Sextett, the K270S is all black). I don't know jack shit 'bout no hip-hop, but they were quite nice with most rock and jazz.
The Equation Audio RP-21 is also an incredibly good closed phone for the money, if you have trouble finding a K270, but I don't remember it well enough to try to compare it to the K270.
