Last month Chromecast Audio gained the ability to sync audio playback across multiple devices and multiple rooms. This made the little circular music puck a cheaper alternative to Sonos, a way to fill your home with sound using speakers you already have for an additional $35 per Chromecast.

Plugging in the little dongle is hardly a difficult task, but it's still less sightly than having the functionality built-in. Throughout this year, B&O Play, Harman Kardon, Onkyo, Philips, Pioneer, and Raumfeld will all join Sony and LG in producing Google Cast-enabled speakers. As they roll out, Google will introduce the ability to sync playback across multiple speakers and rooms using them as well, just as you already can with Chromecast Audio.

You may have assumed Google would treat Cast-enabled speakers the same as those hooked up to Chromecast Audio devices, but now the company has explicitly said so in a blog post. All the more reason to consider giving one of these fancy new speakers a go.
