A:Answer Yes, I bought the Sonos Beam (Gen 2) first and then purchased two of the Sonos One Gen2 and they are in sync wireless. Was easy to set up using the Sonos app. Movies, tv, streaming, it all works perfectly.
To recap, the Sonos ones do need to be powered through a cord. But do not need to be connected via a wire to work with the Beam. They connect wirelessly together.
