Apple Airpod 4 with active Noise Cancellation

Apple's AirPods 4 with Active Noise Cancellation (ANC) use the H2 chip to reduce low-frequency background sounds (traffic, engines) for immersive listening, blending with Transparency mode via Adaptive Audio for situational awareness, but offer less intense cancellation than AirPods Pro due to their open-fit design, providing comfortable, everyday noise reduction with improved call quality and Spatial Audio.
