i've posted a £60 wireless 7.1 surround sound headset in the official thread.
would poo all over the official sony one.
made by a company with a reputation of making products worth well over their asking price.

on another note my ghetto setup for £30 works quite well, my mixamp is now here and set up, charged the new battery i had to buy because one wasn't included, so i should have pretty epic SQ from now on.
rather than buying the belkin mic through your better off with the zalman mic on amazon for £7 and a splitter. sometimes the belkin mic just stops working randomly and you need to unplug it and plug it back in.
