I just picked up a pair on Friday, used them throughout the weekend. Very comfortable (even with glasses), wore them for about 6 hours and ears were not very sore when I was done, just a slight feeling if anything.
The mic adjusts in all sorts of ways, picks up a lot of sound (so not a great idea to have anything running in the same room). So far I would happily recommend it, but keep in mind I've used it for 4 days total at this point.
