Sonos, maker of wireless home audio systems such as the ZonePlayer S5 and iPod docks, may be looking into developing a home theater system. Indication of this comes from a job posting on Sonos' website that seeks to fill the Senior Product Manager, Home Theater Sound position. Little in terms of specifics can be gleaned from the posting, but Sonos is looking for "a successful, experienced home entertainment product leader to help us re-invent home theater sound for the digital age."
