Those looking for another excuse to wear a Bluetooth headset all the time just got it: iTech's $75 Dynamic SolarVoice 908. That awfully long title is applied to a conceptually simple device, a headset with a tiny solar panel on the side rated at five hours of talk time when fully charged. Sadly, though, there's no mention of how long you'll need to bask in the sun to get it there. (AC and USB charging are also naturally on offer.) Unlike earlier examples it's A2DP compliant, so it'll stream your tunes, and boasts integrated noise cancellation, so it's perfect for making your drunken barroom conversations a little more garbled.
