When you want it to, or when the noise levels are exceeding parameters, (audio level, length of time, repeating noise, etc), they move to cover your ears. They are also noise canceling, which will be lovely..

So, here's what I have so far on the overall design of the goggles. The eye cups are essentially smart watch screens, so you can put anything on it. There are 3 microphones per arm, and those headphones are automatic.

Fixed the connections, so now the fans, heater, and headlamp are all working. The SCUCHA lives!!!
