Non-Apple Devices Are Also Supported
While Apple naturally insists that you be running the latest versions of iOS, iPadOS, tvOS, macOS, and watchOS to take full advantage of the AirPods Max, this isn’t strictly necessary as the standard Bluetooth 5.0 headphones will work with any device capable of outputting Bluetooth audio.
Of course, while this is great for non-Apple devices, you’ll want to upgrade your iPhone and other devices if you plan to take advantage of automatic pairing, Hey Siri, Announce Messages with Siri, Spatial Audio, and more.
