If you're not sure which model of AirPods you have, there are a few ways to figure it out. On the box that your AirPods came in, there should be a small printed label that says Model A2032 or Model A2031. If you no longer have the box, you can check the settings on your iPhone: go to Settings > General > About > and look under AirPods. The model number will be listed next to Firmware Version. Finally, if you've already paired your AirPods with an iPhone or iPad and need to know which model they are, open the case lid and hold it close to your iOS device. An icon should appear showing which model of AirPods you have.
