What are the differences between B-Fi (wi-fi) and B1 (Bluetooth)?

• B-Fi uses your home Wi-Fi network for multiroom music streaming and stereo pairing, while B1 uses Bluetooth.  
• B-Fi allows you to name and rename devices, while B1 does not due to limitations of Bluetooth.
• B-Fi requires the Audioengine Control app for initial setup while no product app is required for B1.
