Ah, don’y you just love convergence devices? After all, they do help make life much easier by killing a couple of birds with a single stone, and the Bluetooth Handsfree Sunglasses is definitely one of them. Not only does it offer your eyes some respite from the sun’s glare and harmful UV rays, it also doubles up as a Bluetooth headset that does not look as ridiculous as a piece of plastic hanging off your ear. All in all, the Bluetooth headset has a talk time of 3.5 hours and standby time of 90 hours per charge, and is compliant with Bluetooth 2.0 standards. It has an operation range of 10 meters as usual, and works with virtually all Bluetooth-enabled phones. Each $49.99 purchase comes with a Bluetooth handsfree/headset device, a Bluetooth earpiece and a charging cable. You know what would be really cool? Having the lenses itself incorporate solar panels to keep the headset charged each time you’re outside by harnessing the power of the sun.
