iOS 11 Apple Music Features & AirPlay 2
The iOS 11 update brings AirPlay 2 to your iPhone and iPad and a collection of new Apple Music features.
AirPlay 2 is a new and improved multi-room speaker setup that allows you to use built-in controls and Siri to choose where to listen to music. There is support for existing AirPlay speakers, new AirPlay 2 speakers and even your Apple TV as a speaker.
Apple Music now supports sharing so that friends can see what you are listening to. You have control over making listening public or private.
A new shared playlist style feature lets a friend add to an existing playlist while you are on a shared set of AirPlay speakers.
