Rather than use Wi-Fi to get multiple speakers playing the same audio, though, the Marshall Heddon uses Auracast. The hub connects to services like Spotify Connect or Tidal over Wi-Fi, or other devices through Google Cast and AirPlay, and then shares that audio over Auracast to the Marshall Acton III, Stanmore III and Wobrun III speakers. You can control playback over a connected Marshall app and the Heddon also has RCA ports to connect other speakers or a record player to the system.
