• A1-MR uses your home WiFi network to stream music directly from the cloud or from an Apple Airplay source. A1 is a traditional Bluetooth speaker where music is streamed directly from your phone or other Bluetooth ready devices.
• Your phone, tablet or computer controls the music being played on both systems. However, since the A1-MR is connected to music services through the internet directly, once playing it will act like a traditional radio. This frees up your phone for calls and does not drain the battery.
• The A1-MR can be synchronized with other A1-MRs or the Audioengine B-Fi, creating a whole home solution with independent volume zones. 
• A1-MR uses the Audioengine Control app for initial setup while no product app is required for A1.
