Air Pods will forever change the way you use headphones. Whenever you pull your Air Pods out of the charging case, they instantly turn on and connect to your iPhone, Apple Watch, iPad, or Mac. Audio automatically plays as soon as you put them in your ears and pauses when you take them out. To adjust the volume, change the song, make a call, or even get directions, just double-tap to activate Siri. Driven by the custom Apple W1 chip, Air Pods use optical sensors and a motion accelerometer to detect when they are in your ears. Whether you are using both Air Pods and just one, the W1 chip automatically routes the audio and engages the microphone. And when you are on a call or talking to Siri, an additional accelerometer works with beam forming microphones to filter out background noise and focus on the sound of your voice.
