If you're into this type of headphone, then you'll like it. The sound is clear and loud (the bass is not THAT strong for this kind of headphone), and the fit is perfect. Also, I believe that this might be the only available headphone in this style that has iPod/iPhone control with Siri functionality. think I'll buy a second pair :)
The only negatives I see are sort of cosmetic: the plastic parts do not look quite smoothly finished (although sturdy and inobtrusive), and the packaging is a little annoying and not straight-forward.
