If you're of the persuasion that likes to get their DTS surround sound from a pair of headphones (and we ain't), the kids at Hanwha Japan have just the thing for you. The X-Tube is a USB dongle that contains a vacuum tube-shaped headphone jack that glows blue when in use. When combined with its Windows-only software and compatible headgear (both included) this bad boy promises DTS Surround Sensation (DTS' surround sound effect from 2 speakers), and looks really cool to boot. See for yourself after the break. On sale now in Japan for $45.
