This is pretty awesome! The Orb --- mobile headset doubles as a ring and can be used 30 feet away from your phone. It vibrates if you get a call, but also has a voice-to-text device so you can read messages on your ring.
This is such an amazing idea. I've already thought of two things it might be useful for: a) No headphone cords when running. b) No headphone cords if you fall asleep (just in case they get wrapped around your neck)
