How to Answer Calls with AirPods Gestures in iOS 18

Apple’s iOS 18 introduces Head Gestures for AirPods, giving users a completely hands-free and voice-free way to manage incoming phone calls, messages, and Siri notifications. By simply nodding "yes" or shaking your head "no," you can answer or decline calls without reaching for your iPhone or speaking aloud in public spaces.

The Technology Behind Head Gestures

The feature relies on the advanced motion sensors built into compatible AirPods—specifically the accelerometer and gyroscope. These sensors continuously detect spatial movement and changes in orientation.

To prevent accidental triggers, Apple pairs these sensors with machine learning algorithms running locally on the H2 chip. The system is trained to distinguish between casual, everyday head movements (like walking, checking traffic, or looking around) and deliberate, intentional nods or shakes.

How to Use the Feature

When an incoming call arrives, Siri announces the caller through your AirPods. Once the announcement begins:

  • Nod your head up and down: Answers the incoming phone call.
  • Shake your head side to side: Declines the call or dismisses the notification.

This interaction is fully silent, making it especially useful in crowded or quiet environments where speaking to Siri would be awkward or disruptive.

Compatibility and Requirements

Head Gestures are available on devices running iOS 18 paired with AirPods that feature the H2 chip. Compatible models include:

  • AirPods Pro (2nd generation)
  • AirPods 4 (both standard and Active Noise Cancellation models)

How to Enable or Disable Head Gestures

Head Gestures are enabled by default in iOS 18, but you can adjust them within your device settings:

  1. Connect your compatible AirPods to your iPhone.
  2. Open Settings and tap your AirPods at the top of the menu.
  3. Scroll down and select Head Gestures.
  4. Toggle the feature on or off, or use the interactive tutorial to practice the movements.
