A WiDi adapter, but only for music? It’s true. Up until now, Intel’s Wireless Display technology has been marketed as a means for transmitting video wirelessly from a PC to an HDTV, but apparently it’s good for audio, too. Logitech has chosen CES 2011 to launch the box you see above, the Wireless Speaker Adapter for Intel WiDi-enabled laptops. The idea is fairly simple: place the box near your sound system, and connect it up via a 3.5mm auxiliary jack or using standard analog RCA jacks. From there, you can launch the WiDi software on your laptop, nail the ‘Connect’ button and watch as your PC pairs up with your speakers. If you aren’t equipped to handle WiDi, there’s a similar box, but for Bluetooth. Both are expected to ship in the US and Europe this May for $29.99 apiece.
