At first glance, you might think the guy in the photo above is wearing his sunglasses backwards. However, he's actually getting hiz groove on with the AfterShokz Bluez, a pair of Bluetooth headphones that transmits audio using bone conduction. We've seen the technology before, but never on stereo wireless headsets. Instead of vibrating your eardrums, the Bluez use transducer pads that sit on your cheekbones to send audio directly to your ears. As such, the headphones have an "open-ear" design, presumably to let you hear your surroundings while listening to tunez. If this zoundz intriguing, you can pre-order them for $100 (despite their $129 retail price) from the company's website, or just wait until January when they will make their official debut at CES 2013.
