I also used head-fi.org for reviewing some products, however it is not as helpful if you are looking for a headset that has a mike.
Monster Inspiration (passive) seem best for the moment for that. I run my headphones from 7:30am - 6:00pm non-stop, so finding a non-battery solution works best, plus its lighter..
I ended up with the Monster Inspiration Over Ear Noise-Isolating (Passive) which had better sound rating than the Monster Inspiration Over Ear Noise-Canceling (Active); $50 cheaper and no batteries. Very comfortable and I can wear them all day long. Monster Inspiration look very similar to the Nokia Purity by Monster Over-Ear headphones. Also they are very quiet for people around you, so great in an office environment, and great sealing to keep noise out. (edit: mike works great, as a headset I have no complaints).
as others noted, the Bose Quiet-Comfort 15 sound great, but the mike doesn't work as its optimized for iPhone.
