AirPods connect through Bluetooth, so any Bluetooth-enabled device will be able to connect. However, many features, including battery life check and automatic ear detection, are only enabled on iOS devices. You also cannot check for updates for your AirPods using anything other than an iOS device. Luckily, there are a few third-party apps that add some much-needed functionality for your device with AirPods. You can find a good guide for them online.
