Google Cast for audio is a standard feature on most new wireless speakers these days, and Bang & Olufsen is making sure its B&O Play customers can use that tool as well. The company announced an update for the BeoPlay A6 and the larger (and much pricier) second-gen A9 that will add Google's wireless connectivity. If you'll recall, the option works like a Chromecast for TV: it pulls content directly from the service you're using rather than using your phone or tablet's connection. Back at CES, Google revealed that Cast would arrive on more speakers this year, and B&O is helping it keep that promise.
