It's a WiFi connected speaker which is controlled through an app that you register music services on. This means that the audio ecosystem isn't reliant on streaming the music from your device, but from the service itself. All of the speakers are connected through the main controller app that you can use to group into rooms and setup as a home theatre. I've had their products for the last 7 years and they've never missed a beat.
