4.5 Not bad. Libra69 | 12/02/2012 | See all Libra69's reviews (4) Got this to go with my Turtle Beach PX 21's, mostly used for Modern Warfare 3. It definetly makes a difference. Before sound would be sourced from what sounded like the middle of your head. Now there is a definite surround sound effect, although it's sometimes difficult to distinguish. It makes a huge impact on gameplay as you can hear the rough direction people approach from and act accordingly. Can also be quite confusing when lots of explosions go off, especially with bass turned up, shellshock I guess.
