Chronotech Bluetooth Headset/Wristwatch
This Bluetooth headset gets 4 hours of talk-time when it’s on your ear, making you look like twice the tool of ordinary Bluetooth headset users—of which we are one. At least when you’re not using it, the gadget spends its time on your wrist, uglying up your arm instead.
It costs $128 for an analog face and $120 for a digital one.
