My AirPods will not connect to my iPhone

Test if you can pair them with any other Bluetooth device. This will narrow down if the issue is the AirPods or the device.

Note that Bluetooth can be switched off permanently in Settings, but it also can be switched off in Control Center, so check (blue icon = On).

Try these two troubleshooting methods. Perform a Restore only if Restart doesn't solve your issue.
