The quickest way to check the authenticity of your AirPods is to look up the serial number, which can be found on the underside of the lid of the charging case. It also appears on the bottom of the right earbud. 

Enter that number at check.coverage.apple.com, and if your buds are authentic, you’ll be able to review your Apple warranty status. If your serial number is fake, this won’t work.

When you pair AirPods or AirPods Pro with an iPhone, iPad, or Mac, you’ll see a little AirPods icon next to your device in the Bluetooth settings menu. You should also be able to view the serial and model numbers once connected and you can also use this way to identify your AirPods.
