Noise cancellation in AirPods is a feature that uses microphones to detect external sounds and then counteracts them with anti-noise, canceling the external sounds before you hear them. The AirPods Pro and AirPods Max have Active Noise Cancellation, which uses an outward-facing microphone or microphones to detect external sounds, and an inward-facing microphone to listen inside your ear for unwanted internal sounds. Transparency mode is another feature that lets outside sound in, so you can hear whats going on around you.

To turn on noise cancellation on AirPods Pro, you can press and hold the sensor on the stem of one of the earbuds until you hear a chime. This will switch between noise canceling and transparency mode. You can also turn on noise cancellation from your AirPods Max by pressing the button on the right ear cup toward the front, and you’ll toggle between noise canceling and transparency mode.

The noise cancellation feature in AirPods Pro works by using Apples custom active noise-canceling technology, which is equipped with two microphones, an inward-facing mic, and an outward-facing one. The outward-facing mic analyzes and detects noise coming from the outside so that the system can generate an anti-noise waveform to cancel it. The inward-facing mic listens for and cancels any noise that escapes from the external mic before it gets through to your ears.
