Sennheiser have just shown off two new gaming headsets, with the new devices including a premium option with Dolby technology integrated, with the other priced to appeal to entry-level gamers. Both headsets are available right now from Sennheiser's website.

First up, we have the PC 323D which sports Dolby 7.1 Headphone and Dolby ProLogic IIx sound. The 323D features a CircleFlex design which allows it to adjust automatically to a user's head. This headset comes with its own 3D G4ME1 7.1 USB sound card attached, as well as an open-acoustic design which is said to keep the gamers' head cool through hours of gaming. Volume controls are also featured, on the right ear cup and rounding out the PC 323D we find a microphone which features noise-cancellation technology.

The second headset unveiled from Sennheiser is the PC 310, which sports the same noise-cancelling microphone as its bigger brother, as well as the open-acoustic design.

The PC 310 retails at $60 on Sennheiser's site, with the PC 323D retailing at $160.
