Sony has got to be the proprietary technology king. It seems like a new CE season hardly goes by where it isn’t unveiling something. This year’s offering is its wireless S-Air technology, appearing in a variety of new home theater systems and accessories.

The new S-Air technology is described by Sony as a wireless audio solution for multi-room listening. It works “without complicated set-up requirements, such as IP addresses, WEP keys and pin codes. Wireless audio can be transmitted from the main system in the living room to multiple rooms throughout the home — up to 164 feet — simply by connecting a separate S-AIR Air Station receiver/speaker into a power outlet.”

Sony unveiled four home theater systems, such as the pictured DAV-HDX576WF, which will make use of S-Air in the arena of offering a rear wireless speaker kit which will be available in March for around $149. Also being made available at the same time will be the separate room kits for around $120.
