Customize Your AirPods Commands
Finally you can control how your AirPods change your music when you tap on them and set it up to be different for each ear. With your AirPods connected you will need to go into settings and make the change. This will stick with your AirPods, so you don't need to change this every time you connect them.
Go to Settings -> Bluetooth -> Tap on the i to the right of AirPods -> Tap on Left or Right and choose what you want a double tap to do. You can choose from Siri, Play/Pause, Next Track, Previous Track or simply turn the double tap off.
