Canada-based Psyko Audio Labs has officially released its 5.1 PC gaming headset we briefly sampled at CES. Available in North America, the headset uses 3D sound technology that helps wearers better place their opponents in first-person shooter games through sound. The headset uses wave guides to send sound to an ear, producing a natural latency rather than an electronically generated one, for what is a more natural delivery, Psyko says.
