Here is a pair of smart glasses that lets you listen to music, track daily activity, listen to navigation, and make calls on the go. They use bone conduction technology to allow you to listen to audio while keeping your ears open. Vue lets you make handsfree calls, track your steps/calories/distance, and interact with it using simple gestures.
Vue glasses are compatible with iOS and Android devices. They have a battery that lats up to 5 hours (talk time). These are rain and sweat resistant.
