Ear Force X11 Amplified Stereo Headset with Chat

The Ear Force X11 is the perfect headset for XBOX gamers who want immersive game sound and XBOX Live communication at a great price.
Overview:
With an in-line amplifier and separate connectors for mic and line signals, the X11 also makes a great PC gaming headset.

Before I had this headset, I was using speakers from an acer h223 monitor, and the sound was horrible. This will review will be based on me playing Modern Warfare 2 since this is why I bought the headset, that and my fiance always complaining about the sound at night.
The Good:
Now, I am able to hear EVERYTHING. At first it was overwhelming, I hear things in the game I didn't know existed. I use the Ninja Pro Perk so my steps are silent, so that I can hear everyone else's steps. Now I can hear when someone is walking in a house, on metal stairs, or in a grassy field. I can hear "boosters" place their insertions and hunt them down. I hear silencers going off in the distance. I know when someone is to my left or the right.
