Adjust the features of your AirPods
Open the AirPod Case, then go to Settings > Bluetooth on your iOS device. Tap next to your AirPods in the list of devices. Here's what you can do:
Name your AirPods
Tap the current name. Then enter a new name for your AirPods and tap Done.
Choose your double tap
When you double-tap either AirPod, you can use Siri to control your audio content, change the volume, or do anything else Siri can do. You can also choose to have double tap only play and pause your content, or you can turn it off completely.
Turn Automatic Ear Detection on or off
By default, AirPods sense when they're in your ear and receive the audio from your device. AirPods also pause and resume playback when you remove one of your AirPods, or stop playback—and won't resume—when you remove both. When you have Automatic Ear Detection on and you're not wearing your AirPods, audio plays through your device's speakers.
When you turn off Automatic Ear Detection, these features are off and all audio plays to your AirPods whether or not you're wearing them.
Set Microphone to left, right, or automatic
There's a microphone in each AirPod, so you can make phone calls and use Siri. By default, Microphone is set to Automatic, so that either of your AirPods can act as the microphone. If you're using only one AirPod, that AirPod will be the microphone.
You can also set Microphone to Always Left or Always Right. These set the microphone to either the left or right AirPod. That AirPod will be the microphone even if you remove it from your ear or put it in the case.
Clean your AirPods with charging case
Clean your AirPods with charging case regularly with a soft, lint-free cloth. Don’t get moisture in any openings, and don't use aerosol sprays, solvents, or abrasives.
Find the serial number
The serial number of your case is on the underside of the lid.
If your AirPods are connected to your iOS device, you can also go to Settings > General > About > AirPods for the serial number.
