Apple details the process of adding noise cancellation to AirPods 4

The new AirPods 4, announced along with the iPhone 16, has some interesting features Active noise cancellation (ANC) in the most advanced versionAn asset that can undermine the effectiveness of the source, which is noticeable due to the “open design” of this model.
