One of the main perks of using an iPhone with AirPods is streamlined connectivity.
Connecting the AirPods Pro to an Apple device is very easy, thanks to the embedded H1 chip. Once you open the AirPods Pro case a card on your iPhone will pop up prompting you to connect the device. After establishing this connection, your AirPods Pro will connect to all devices attached to your iCloud account. Once you do this, you can set up things like Find My AirPods.
Pairing the AirPods Pro with an Android or Windows PC is a little more complicated, but not any more than any other brand of Bluetooth earbuds.
