Does anyone know how to register AirPods to Apple ID devices list?

AirPods are AMAZING, indeed! I just got a set, myself, and couldn't be more impressed.

The good news is, they're setup in iCloud so you can keep track of them that way with Find My AirPods, but no need to actually "register" them with Apple for service.

Here's a great resource, however, if you do want information on what's available for service options for your AirPods.

You don't need to register - but you need a note of the serial number to get replacement parts (replacement airpod or charging case) - its treated as a Genius Replacement - and you can't buy the replacement parts without the original serial number. If you bought at a reseller rather than the Apple Store make sure you note the serial number - its not recorded on any of the devices you pair with.

You don't need to register for warranty.

I would think that you do not add them to the device list as they are not a device, but an accessory for your devices.
