The Soundbar 500 and 700 allow the user to run their music with their voice, a remote, or the Bose Music App. The reliable voice function uses Amazon Alexa — which can also tell you the weather, and answer your curious questions — to play whatever you desire. You can find more info on this link.
Right now it's not possible to make speakers on the same WiFi, play at the exact same time. The issue is with the limitations of the technology we use on a daily basis. Our routers at home can sometimes be too slow at processing, possibly our connections to the Bose Music servers, and also the latency between the speakers and your router when connecting them using WiFi.
We are still making improvements on this as much as we can. There are a few steps to reduce this latency, but again there is no guarantee that these will work:
I hope I have provided some helpful information on this issue. Please let me know if you have any other questions.
