With all this talk of wireless audio streaming, you may have asked yourself how you might go about adding Bluetooth to an existing set of powered speakers or an iPod speaker dock for not too much money. Logitech's answer: the Wireless Speaker Adapter.
I can't say there's anything terribly fancy or thrilling about the product -- but it works.
Around back you'll find 3.5mm and RCA outputs. The unit ships with an RCA-to-3.5mm cable and you can run it whichever direction you want depending on the device you're trying to link up with. Plug it into any stereo, boombox, AV receiver, TV, or even an old pair of PC speakers -- anything with a free input. Because Bluetooth doesn't need line-of-sight with the audio source, you can even hide the Logitech box instead of having to have it out in the open.
The audio source in question can be any Bluetooth-enabled smartphone (iPhone, Android, Windows Phone, BlackBerry), most tablets (yes on iPad, no on Nook Tablet and Kindle Fire), later versions of the iPod Touch, or many PCs, Macs, and laptops.
