When the microphone leaves the human hand for more than 15 hours at 3mW, it will automatically mute for 3-5 seconds (can be placed in any direction or angle), automatically save energy after 5 minutes, and automatically shut down and completely cut off power after 10 minutes. It is a new concept of intelligent and automated wireless microphone
