4.2 Other functional requirements 

  1. When charging, the indicator light flashes slowly. When charging is completed, the indicator light goes out..
  2. A single temple can be used normally, and the touch keys for operating the two temples have different functions. The left temple reduces the volume and the right temple increases the volume. The left and right temples can be controlled to answer \ hang up the phone, play \ pause music and start the voice assistant.


4.3 fundamental functionOne Hall switch and one touch key on each side.
