I take the listener on an iPhone4 with FiiO E11 amplifier and am thrilled by the sound. Whether Hip Hop, rock, jazz or classical music, the sound is second to none for me. And I also processing and design like insanely good. The Bose headphones are made entirely of plastic, other clatter and shake. The only alternative with respect to look, feel and sound would have been for me the B & W P5, however, has no noise-canceling, is more expensive and not nearly as cool looks like the Monster Inspiration listeners Brushed aluminum and leather. Interchangeable headbands I do not miss the way.
