I find it quite amazing that none of the previous reviewers cared to comment on the ridiculous... what would usually be a head strap, but in the case of the HS600 is a giant, unadjustable plastic ring that only makes contact with your head through a cheap piece of foam glued to the top. Literally, there are 3 inches of air between the side of your head and the plastic.
I've never seen a pair of headphones that could make anybody look like an absolute idiot, so naturally avoid them like the plague if you have a webcam. It's no wonder the product shot is form the side, if it was head-on, you'd have some idea of how stupid it looks.
Also, I've been wearing it 10 minutes and my ears are already starting to irritate. I gave it 2 stars because there doesn't seem to be a problem with the recording or sound quality; if only it had been designed to be worn by a human head, perhaps there'd be no problem.
