I also bought the HyperX about 2 weeks ago, for £52... bloody bargain.
Design and comfort is very similar to my Beyer DT770s, which is very high praise, and they fit even on my huge noggin'. Audio is as expected from a gaming headset; to be honest it's decent - if you've never had a play with any audiophile or music production hardware then you'll probably be blown away by the HyperX, it doesn't really do anything ''wrong'' (well, maybe a little too bloated bass), it just doesn't have the detail and resolution of higher end gear. To be honest for the money they're the best out there right now.
