A:Answer The microphone has a 90 degree flip up and down action. Whenever you flip up you are muted, and when you flip down you're unmuted. There is also a feature, somewhat like Alexa or Siri, that'll say "Mic on" or "Mic off" and if you have the microphone off for a while it'll announce, "Auto-shut down initiated" I'm assuming it has that feature to save your battery.
