I had played so far MW2 only without a decent headset. According to a lot of my jaw down when I was wearing the first time X11: I can now hear enemies creep eg through the grass. Or people who shoot with silencers are now easy to locate. Very nice is that I in-game chat and play independently can now make loud and soft. The X11 is very comfortable and easy. You get used to it very quickly. Can not imagine without playing me.
