Users on Sono's official forums are reporting that they can control the playback features for their Sonos speakers with Android Wear watches. The play, pause, next and previous song controls can be managed from your Moto 360 for example. Unfortunately it doesn't appear that volume control is currently available, so capabilities are limited.
An official from Sonos has stated that the functionality being reported by users is "due to the openness of the Android operating system and the existing integration on Sonos. Some Android Weat devices may already work with Sonos. However, we are not actively testing or developing this functionality at this time."
It may not officially be supported at this time but, if you're looking to coax more value out of your Android powered watch, this is a nice one to add anyway.
