Possible cause: Wear Detection is disabled.
Solution:
1. Go to Settings → Interaction and turn on Wear Detection.
2. After Wear Detection is enabled, removing the glasses will turn off the optical engine and audio within 5 minutes. The glasses will power off after another 5 minutes.
Note: After Wear Detection disconnects the glasses, the phone determines where audio is routed. If another Bluetooth audio device is connected, the phone may switch audio to that device instead of the phone's built-in speaker.
