Bluetooth headsets come in a variety of shapes and sizes ranging from small earpiece designs to over the head headset looking things. I’ve personally shyed away from the funky earpiece design as being (a) uncomfortable and (b) pretentious looking. Think Geek now has Bluetooth enabled sunglasses that integrate the headset into the sunglasses. Finally, some great looking Bluetooth sunglasses that will keep you connected while you are on the go, but without the cyborg, pretentious looking earpiece that is typical of most other Bluetooth headsets.
