Cool High Tech Sunglasses
Designed with sportspeople in mind, the Recon Jet sunglasses come jam packed with high tech features, including GPS and Bluetooth capabilities, an embedded HD video camera, speakers and a microphone. They also include a powerful integrated microcomputer that can provide detailed, accurate sports performance metrics for their wearer. Another impressive feature is the optical touchpad, which facilitates the glasses being operated by gesture control as well as standard button pushes. The Recon Jet glasses also aid endurance athletes by having a battery life of four to six hours, which can easily be extended by switching over the batteries.
