A:Answer I own this set and it does not support Bluetooth so you will need to connect your soundbar using an HDMI (for ARC), Optical, or Analog connection. There are also adapters you can purchase to add Bluetooth to this TV. If you only need to connect the 2 rear Vizio wireless speakers that come with the large soundbar it should work fine as long as the soundbar itself is plugged into one of the above mentioned inputs. But to answer your question simply...no, the main soundbar unit cannot be used wireless without an adapter.
