Much more imporant than price, sound quality, color, case is WEIGHT. I had a pair of these for a week, and promptly returned them in exchange for Bose NX700's. THE APM's sounded better, had better noise cancellation, better functionality and would have been worth the extra $100, but they were just too heavy to wear for more than 30 minutes. Aluminum? Stupid. Sure, cool, but stupid on headphones. I still have the Sonys and can wear them (like my Beyerdynamic Studio headphones) for a few hours and (mostly) forget I have them on.
