wireless World of Warcraft rig, but they've got one feature guaranteed to make hardcore PC gamers swoon -- they claim to be the very first to offer truly three-dimensional surround sound. Embued with the latest revision of Creative's THX software collaboration (dubbed THX TruStudio Pro) the Sound Blaster Tactic 3D series "delivers a 360 degree surround sound gaming experience so gamers can hear sounds clearly from the front, back, above and below." There's also a set of customizable audio profiles so you can tune all the other presumably-more-powerful TruStudio algorithms just the way you like, though it's not clear whether Creative's included on-board memory or just has a desktop app. In terms of hardware, the $60 Tactic 3D Alpha comes with 40mm drivers, a USB audio adapter and a detachable noise-canceling microphone, while $90 buys you the Tactic 3D Sigma with larger 50mm drivers and a steel headband as well when both debut later this month. We have to admit, we're curious to hear for ourselves whether they work as advertised -- they sound like just the thing for a nice, relaxing Portal speedrun. Full PR after the break.
