You can add Sonos to the list of companies that are aiming to offer Android Wear support for its products. A post on the company's forums shows a beta version of the Sonos Android Wear app running on a Moto 360 that allows users to control the wireless connected speakers from Sonos from the smartwatch.
Apparently the Sonos app has pause, forward, and back features but volume control is not yet available in this beta version. There's no word on when the Android Wear app will be released but at least it's in development. Would you control your Sonos speaker with a smartwatch?
