1. Make sure that your iPhone or iPod touch has the latest version of iOS or that your iPad has the latest version of iPadOS.
2. Put both AirPods in the charging case and make sure that both AirPods are charging.
3. To make sure that Bluetooth is on, go to Settings > Bluetooth.
4. If your AirPods are connected, make sure that they're selected as your audio device. If your AirPods appear in the list of devices but they don't connect, go to the next step.
5. Close the lid, wait 15 seconds, then open the lid. Press and hold the setup button on the back of the charging case for up to 10 seconds. The status light on the front of the charging case should flash white, which means that your AirPods are ready to connect.
