The new gestures are available alongside current gestures, which allow users to summon Siri with a tap. All of the options for your AirPods can be accessed in the Settings app while the AirPods are connected to your iPhone or iPad. Here's how:
- Open your AirPods case while your AirPods are near your iPhone so they connect.
- Open the Settings app.
- Select "Bluetooth."
- Tap the little "i" button next to your AirPods.
You can set different gestures for the left and the right AirPod. Options include Siri, Play/Pause, Off, Next Track, and Previous Track. The latter two options are new in iOS 11.
To set a gesture, you only need to tap it. If you choose Next Track for one AirPod and Previous Track for another, you can quickly and easily switch between songs that are playing, without the need to invoke Siri.
