We are no stranger to SteelSeries products here with stuff like the Starcraft II Series Keyboard and the Gaming Mouse and Gaming Surface.
At CeBIT in Germany, the company announced the Siberia v2 for the PS3, and it is also compatible with the Xbox 360, PC, and the Mac.
One of the main features of the Siberia v2 is LiveMix, which showed up on the Spectrum 5XB. This thing separately controls the volume of voice chat and other in-game sounds.
You should be able to purchase these Siberia v2 headphones sometime in the third quarter for a price of $119.99.
