According to my experience these smart glasses equipped with Bluetooth StageSound microphone hands-free waterproof technology are a major disappointment. The sound quality is extremely poor and muffled. While they are marketed as waterproof, they are not great for sweaty gym workouts .The worst part is that the battery dies quickly, leaving you hanging in the midst of an important call or recording. These glasses might look sleek, but they don`t live up to their promises..
