Last week, an odd story emerged on Reddit when original AirPods Pro users noticed that the latest iOS 16.1 beta had added Adaptive Transparency to the first-generation model. As we speculated at the time, this appears to be a bug and it seems like the next beta iOS 16.1 will remove the toggle from the Settings app altogether.
Transparency Mode is a feature available in the AirPods Pro and AirPods Max that uses the built-in microphones to let users hear the world around them without having to take off the earphones. The new AirPods Pro 2 expand on this functionality with a new Adaptive Transparency Mode feature.
