MULTIROOM
Use the Bang & Olufsen app to add compatible speakers
to create a Beolink Multiroom group and play your music
simultaneously in different rooms. Alternatively, stream to
more speakers using AirPlay 2 or Chromecast.
Join an ongoing Beolink Multiroom experience by holding
your hand for 2 seconds at the top of the dots on the rear
until you get audible feedback.
