As i said, im no sound expert but i think the psykos are great. Can only order from USA IIRC which is somewhat of a pain.http://www.psykoaudio.com/#axzz23JUBaeHr
My 2nd fave is this one:http://www.speedlink.com/?p=2&cat=41A3&pid=25159&paus=1
Had adjustable volumes for each speaker (front, centre, rear) so you could adjust on the fly if desired. Ear cup was too small to cover ear but wasnt too uncomfortable to wear for extended periods of time. Ordered them from the UK.
Then i also had these 7.1 ones:http://www.cravingtech.com/sennheiser-pc-333d-gaming-headset-review.html
The 7.1 came from an inbuilt soundcard so i dunno about how good that is. Problem was (as mentioned in the review) the ear cups are small and tight and squashed the fuck out of my ears after only a little while.
My first pair were the speedlink ones after i spent time searching what pair to buy. This is probably 5 years ago. A while later my Dad was talked into buying the sennheiser ones by somebody @ JB hifi or the like but they werent for me. Then i got the psyko ones for a present from my brother after he read about them in a tech mag. Havent needed another pair since.
Id be interested if anybody else has a 5.1/7.1 pair they recommend. But none of that synthetic 5.1/7.1 created from stereo sound crap like the turtle beach @ EB.
