$ 700 is one with 2 wireless bluetooth speakers. $ 800 is with 2 wireless bluetooth speakers that are rechargeable, so they can run for hrs outside and such….

speakers are also WiFi and there is a free app to stream various music services. Biggest upgrades over sb one sound bar is that this version is designed to be a home wireless system as well as a soundbar. it comes with separate bt/wifi switch, ethernet port if you need,
