As CES 2015 starts ramping up, Google has announced Google Cast for audio. This integrates the same tech behind Chromecast into speakers, soundbars, and A/V receivers to let you cast your music from Android, iOS, and the web.
Google Cast Ready speakers pull content directly from the cloud, so you'll get the best audio quality and can freely multi-task on your phone, tablet, or laptop, all without straining the battery. These speakers will work with a growing list of apps including Deezer, Google Play Music, iHeartRadio, NPR One, Pandora, Rdio, TuneIn, and many more.
Google Cast is supported by chip makers Broadcom and Marvell, along with others. Sony, LG, and HEOS by Denon will all produce the first Google Cast Ready speakers, which are due out in spring 2015, with other brands releasing compatible products later this year.
