ok, i used these for a few hours last night, overall i like them, much better than what i had, but that's not saying much cause what i had was ok, but definitely not designed for long gaming sessions.
below is what i would give out of 10 in my criterias:
Sound Quality - 8
Comfort - 8
Weight - 7
ease of use - 7
Battery life - unknown, i haven't used it enough to comment
Sound Quality - i like them, very nice compared to my last headset, i can't say they are better than any others due to me not having tested any others lol
Comfort - very comfortable, the fit right over my big ears which helps block out surrounding noise and doesn't press on my ears like my last headset did which started to hurt after a few hours. My only gripe is that the material used on the foam does make your head a bit warm after a while, but that's no biggie
Weight - definitely heavier than my last headset, but that is too be expected, my neck will adjust
ease of use - initially it was easy, just plug and play, but that was when i used the dongle stright from one of my usb ports, but when i tried using my extender with the dongle i could not hear anything, even when i used different usb ports so i had to go back to using the dongle striaght from a usb port which is no train smash since i used to do that, i will test some more tonight and see if it was my fault.
so in the end, like i said, i like them and i'm happy with my choice, for the price compared to other wireless headsets, these are awesome
