Your AirPods would need to be well-charged, 

Charge your AirPods and learn about battery life

and 

in discovery mode. (flashing white) in order to pair.

With that, If you haven't already, you might want to try wearing your AirPods, 

and 

on iPhone: Try Settings > Bluetooth > tap "Not Connected"

If more help is needed:

Your iPhone may need updating to the latest compatible iOS version.

Eg: About iOS 16 Updates - Apple Support (says iOS 16.5 is the latest)

(The firmware on the AirPods can then be updated automatically when paired).

If iPhone is already using iOS 16.5:

Try re-starting it : How to: Restart your iPhone)

The AirPods may need re-setting:
