Hanwa’s USB Valve Dongle Upgrades Your Windows Machine With DTS Audio
Making it a bit easier: a USB dongle that looks like one of those tubes and allows you to upgrade your computer with DTS sound. You’ll need two more things to enjoy DTS sound on your computer: “DTS Headphone Deck” (a piece of software) and DTS-compatible headphones (AH-516), but Hanwa throws in both items when you buy the dongle.
The X-Tube can only be used with Windows machines (XP, Vista or 7). on sale in Japan today for $45 (including the headphones)
