Play audio on AirPods (3rd generation)
When you’re wearing your AirPods (3rd generation), you can use the force sensor to play, pause, or skip audio playing on your iPhone, iPad, Apple Watch, Mac, or Apple TV.
Play and pause audio
Wear one or both AirPods, and make sure they’re connected to your device.
Open an audio app, then play something. For example, you can play a song in Apple Music, or listen to an audiobook in the Books app
.To pause audio while listening with both AirPods, remove one. When you return it to your ear, playback resumes automatically.
If you don’t want AirPods to automatically play and stop the audio, you can Change how you end a call or mute yourself with your AirPods.
Stop the audio
Remove both AirPods from your ears, or if you’re wearing just one, remove it.
Skip tracks
You can double-press the stem on either of your AirPods to skip to another track in many audio apps. For example, you can double-press the stem to skip to the next song in Apple Music, or to skip to the previous episode in the Podcasts app 
.
To skip to the previous song, triple-press the stem.
Protect your hearing
You can monitor and limit the volume of your AirPods using your iPhone or iPad. See Check your headphone levels in the iPhone User Guide.
