There are some features of AirPods that are only available on Apple devices. Off the top of my head those are:

- Easy Pairing (if you just open the case next to an iphone, a dialog box comes up where you can just tap 'pair' and you're done)

- Automatic Pause (if you remove an ear, it pauses it)

- Reassign touch gestures

- Audio Sharing

- Ability to choose which ear's microphone you wish to use

- Lossless audio quality
