If your glasses have stopped responding suddenly, we recommend trying to reset them. To do this, place the glasses inside the case. Make sure you follow our charging guide here to ensure the glasses are properly seated inside the case.
Find the small reset pin next to the USB-C charging port on the case. Insert a pin into the hole and press for 5 seconds. The charging port should flash red. See the video below for reference.
Once the reset is complete, take the glasses out and test to see if they respond.
