The earcups feature a noise reducing foam, which helps you to focus on the important audio or voice communication, & not being disturbed or interrupted by outside noise. The Siberia v 2 for PS3 features a retractable microphone that can be hidden in the left earcup, which means you can use it when you need it, but don’t have to flash it in public if you don’t want to. For Xbox 360 players, the headset is also compatible for in-game audio & Xbox LIVE communication. Users can simply connect to the Xbox controller through a double-sided 2.5mm connector. Steel Series’ Live Mix™ feature is now accessible to all platforms from Xbox 360 & Play Station 3 to PC & Mac. The Live Mix levels range from OFF, which is unaltered in-game & voice sound to LOW (game sound is reduced by 5db when your teammates are talking), MEDIUM (game sound is reduced by 15db), to HIGH (game sound is reduced by 25db). By providing optional levels of Live Mix, users will have the ability to control how much of the game sound they want to hear balanced over the voice communication.
