Never got the original working, so sent back to the shop for a refund, and purchased a new one from Game. Then last week what arrived in the post.... a free upgrade to a wireless one form the original online shop!
Not used it yet, but the wired one is pretty good. Good sound quality and gaming chat is better IMO. Good length of cable, can lie in bed and use them, but my gawd do they get in the way. Easy to set up etc.
What to do with the wireless ones? Sell on and make a profit or sell the wired ones at say £30 used?
