How to find my airpods

Ref: How to find your lost AirPods - Apple Support

To attempt to find lost AirPods, the following must be true:

• Find My iPhone must have been enabled BEFORE they were lost.
• The AirPods are within range of your devices (iOS or macOS).
• They are not in their charging case.
• They are still charged.
• The AirPods have not been reset.

Then you will not be able to locate them via Find My. You will have to do so, the old fashioned way, by going to look for them.
