The Orb, A Bluetooth Headset That Turns Into A Ring. Every now and then you see a product and you just assume that it’s a concept. I mean, heck, it’s just too smart for anyone to be producing it! And every now and then you’d be entirely wrong, like now. The Orb is an actual Bluetooth headset that transforms into a ring and vice-versa. Wear it like a ring and its Flexible OLED (in the Deluxe edition) will display caller info, calendar items and voice-to-text info.
