After a long time I finally managed to get my hands on these, and it was well worth the wait.
Set up in under 60 secs and immediately noticed sounds in the xbox live dashboard I had never heard before.
Once I started gaming with them it was hard to believe there was so many sounds I never notice or heard before, they deliver superb sound and absolutely help pin point sounds ie gun fire, planes, choppers and footsteps ect - 1st 3 games I played on MW2 I came top, coincidence? Doubtful !
Anyone that requires 5.1 or 7.1 surround sound should defiantly consider this as a alternative option.
Are they worth the money? Well considering how much a game cost and how long some of the last, I feel these offer a great value for money.
