Review on Black Smart Audio Glasses with Bluetooth Connectivity and Polarized Sunglass Lenses by Joe Glass

Great idea Bluetooth sunglasses! If you keep the volume below 70%, others can probably hear the sound. They look attractive, feel light (I don't know how long they will last, they will be updated). The sound quality is ok, the device is not particularly difficult to sync. Good price. 8 hours without charging, 6 hours of music, 4 calls at the hotel. The lenses themselves are quite dark and polarized, the glasses fit snugly enough, convenient charging is included, although the cord is short. The packaging is pretty cool, cool, cool, tight, tight, but nothing really reusable.
