Apple’s wireless AirPods automatically pause music playback when one or both of the buds are removed from your ears during use. But if you’d prefer to control play/pause with touch controls without having to remove AirPods from your ears, Apple has given users a way to do so.
While your AirPods are connected, go to Settings > Bluetooth on your iOS device and touch the “i” to access the information screen for your AirPods. On that screen, you’ll be able to change a number of settings, including the Double-Tap controls.
AirPods are set by default to control Siri with a firm double tap — here, you can switch the setting to Play/Pause instead.
In switching this setting, users are giving up immediate double tap access to Siri. However, that tradeoff is somewhat mitigated if you’re using an iPhone 6s or later, or a 9.7” iPad Pro.
