Amazon.com Product Description:
Installing rear speakers has never been easier than with the wireless Sony WAHT-SD1 adapter. Simply connect the included 200-Watt amplifier and infrared receiver and place the rear speakers of your BRAVIA® Theater system exactly where you want them. Without the hassle of custom installation, you can avoid the tedious job of hiding speaker wires and spend more time watching movies with room-filling surround sound.

Rating : - Not completely wireless
We purchased this item because we needed some of the speakers wireless, however, with this unit they must still be wired to a separate unit that transmits to the stereo.
