This follows the addition of AirPlay 2 to the BeoPlay M3, BeoSound 1 and 2, BeoSound Core, and BeoSound Shape earlier in November, to be followed by the BeoPlay A6, BeoSound Essence, and BeoSound 35 by the end of December.
AirPlay 2 should be enabled as part of an automatic software update for each speaker, but the software version can be checked and updated manually via the Bang & Olufsen app for iPhone and iPad if necessary.
With the AirPlay 2 update, these Bang & Olufsen speakers now support multi-room audio when paired with other AirPlay 2 devices, such as the HomePod, Apple TV, Sonos speakers including the One, Beam, Playbase, and second-generation Play:5, and select Denon and Marantz audio receivers.
AirPlay also allows for Siri control of Apple Music or Podcasts playback on supported speakers via iPhone, iPad, iPod touch, HomePod, and Apple TV.
Bang & Olufsen speakers will appear in the AirPlay device picker within most apps and in Control Center on devices running iOS 11.4 or later.
AirPlay is Apple's wireless streaming protocol that enables users to easily stream audio from iTunes on a Mac to supported speakers, as well as from iPhone apps like Apple Music, YouTube, Spotify, Hulu, and Netflix, to AirPlay-enabled speakers, now including these BeoPlay and BeoSound options.
