These are wireless earphones in clear glass frames. While they don't have the functionality of smart glasses, they connect to smartphones and iPhones via Bluetooth without blocking the ear canal. They are perfect for those who want to enjoy music or radio constantly. The instruction manual is in Chinese and English, but you can turn the device on and off by long-pressing the play button. After that, you can control playback and call settings from your smartphone, so you shouldn't have any other problems. The lenses are clear. They are not sunglasses.
