Sony is hoping that consumers will soon be walking on S-AIR—or at least listening to it.

Four of their new home-theater-in-a-box products will include S-Air technology, which basically means that wireless technology will stream audio from your main audio system to other rooms or rear surround speakers, up to 164 feet away.

Just connect the receiver/speaker into any outlet, and you’ve got yourself a whole-house system; there’s no IP, no WEP and no other codes to worry about.

Each unit has a 5-disc upscaling DVD/CD player and Sony’s Digital Media Port, which opens up your wallet to all kinds of optional accessories. Here’s what each unit does not have in common:

• The DAV-HDX576WF is designed to match the BRAVIA in looks and price; it offers floor-standing speakers, one S-AIR receiver/speaker and one wireless rear speaker kit. ($500)
• The DAV-HDX277WC includes one receiver/speaker, with the option to add the wireless speaker kit. ($400)
• The DAV-HDX279W includes the wireless kit, but no receiver/speakers; those can be purchased separately. ($400)
• The DAV-HDX275 comes with nothing, with options for both the wireless speaker kit and the receiver/speakers. ($300)
