Maximum PC: German peripherals maker Roccat just added the Kave XTD Stereo to its growing line of audio peripherals, along with a combat themed version that it's calling Kave XTD Stereo Military. Other than the color scheme, these two headsets are the same -- both sport 50mm neodymium magnet drivers shoved inside padded earcups. According to Roccat, these are ultra-lightweight but durable headsets.
