No Siri. Unfortunately, you won’t have access to Siri when you use the AirPods on Android.
No Spatial Audio. This is exclusive to Apple devices running iOS 14 or later with the AirPods (3rd gen), AirPods Pro, and Beats Fit Pro.
No Audio Sharing. Once again, this feature is only limited to Apple devices running iOS 14 or later.
Auto-pause. On iOS devices taking one earbud out of your ear will auto-pause your music while placing it back in your ear will resume music. This isn’t available on Android.
Using a single AirPod. Unfortunately, if you’re on Android you won’t be able to just use a single earbud.
Seamless switching. To switch output devices with the AirPods on Android/Windows, go into Bluetooth settings and manually connect and disconnect the AirPods accordingly.
Checking battery life. If you’re on an Android device, you can’t check the battery life of your AirPods the same way you can on iOS.
Customizing any feature. In the settings app of iOS, you can customize a number of features ranging from playback controls to a fit-test with the AirPods Pro. None of those features are available on Android.
Firmware updates. Apple doesn’t currently make a device management app for Android, which means that you will need access to an Apple device to install any updates.
