Summary: I'm new to the site, and would not call myself an audiophile, although I do appreciate great sounding music played through good quality equipment. I share the kindred hate that many on this website seem to have of hearing music played through TV/Laptop/Phone speakers..
Pros: Comfortable and very well constructed (including the cable). Punchy base and very clear, if cold sounding mids and highs.
Cons: A bit too "cold" sounding... with each instrument or voice sounding separate from other sounds
Summary: The Sennheiser PX 360 headphones look good, and are very comfortable, at least to me, but the earcups fit just nicely over my ears. Any smaller and I would not be able to fit these over my ears. What with these being advertised as circumaural headphones, the earcups should be bigger.
Pros: good bass and mids, nice-looker, nice case, good portability
Cons: strange emphasis on particular frequency range, small cups may not fit everyone, fragile, non-detachable cable
