You are only able to connect one Move at a time over Bluetooth using an iPhone.

Limitation of Apple’s OS that it won’t allow 2 simultaneous Bluetooth connections with non-Apple speakers.

Well that’s a bummer … so WiFi is the only way to have multiple move speakers simultaneously?

Yes, over Wi-Fi, you would be able to stereo pair the speakers, or group them together if you just wanted the same music to play in different locations.

Or have you could make this with another devices? And yes, that is one reason (more as a advantage and the Sonos multi-room sign)
