The Soundmagic HP100 is very good, but strong in the treble and lean in the upper bass to lower mids. The Logitech UE6000 may be even better depending on how you play it (Passive mode flat, or Active mode with bass reduction). The v-moda M100 that's due in a month or so may be better than either of these, for ultimate sound quality and proper balance. I also use the Sennheiser Amperior, which has a big emphasis in the lower mids, but sounds very good to me albeit quite dark. And I have a Sennheiser Momentum on the way, which I hope sounds better than the Amperior.
