AfterShokz Bluez 2 [$99] are wireless bone conduction headphones built to deliver an open ear listening experience. The innovative design gives you the ability to remain aware and comfortable while tuned into your favorite mobile devices. Patented audio and design technologies guide mini vibrations through the cheekbones directly to the inner ears. They deliver premium sound without blocking or covering your ears. The patented bone conduction technology was initially developed for military special operations and law enforcement and now it’s priced for everyday use. Through a suite of proprietary audio technologies and the only completely open ear design, AfterShokz headphones deliver premium stereo sound and a promise of safety and comfort that is second to none. We gave them to our resident running freak – they run about 80 miles a week – and they reported that AfterShokz Bluez 2 are comfortable, sound great and are easy to use while pounding the pavement. I used them in my office to listen to music and podcast and literally forgot I had them on. A really great set of Bluetooth headphones and a great price. You can use them for phone calls too!
