Sonos just announced that it’ll be adding support for Apple’s new AirPlay 2 standard to its speakers next year. In addition to making it easier to play music from iOS devices, AirPlay 2 means that — much like the recently announced Alexa support — users will be able to use Siri on iOS devices and eventually Apple’s HomePod to control their Sonos systems.

AirPlay 2 also enables multi-room support for AirPlay speakers, meaning that you’ll be able to integrate Sonos devices with other AirPlay 2 speakers for a seamless experience across your home — including Apple’s HomePod, which was originally announced as a competitor to Sonos’ devices.
