Meet the Orb: a cool ring that can be transformed into a headset you can wear on your ear quickly. It offers hands-free calling and bone conduction audio. That means you don’t have to put the device inside your ear. The deluxe edition will have an E-ink display to offer caller ID and calendar reminders. To use it, you just have to take the ring off and twist it around the hinged joint. A pretty crazy idea, isn’t it?
