There's no dearth of Bluetooth-based wireless speakers
out there, but Logitech
put a nice bit of polish to this new Pure-Fi Mobile set, which is always appreciated. The A2DP stereo manages 12 hours of battery off of rechargeable batteries, and can work as a speakerphone with its built-in noise canceling mic. You can charge it up via USB or a wall jack, and there's of course an aux-in jack when you're not feeling in the wireless mood. Expect this one to hit Europe and the States in June for $150.
