A shot of Avnera's AudioMagic chip on a board. The two blue things at the bottom are antennas. A pair of chips--a transmitter and receiver--go for around $14.

Best Buy and Acoustic Research have already released products using the company's chips, and Panasonic probably will soon. Panasonic is an investor. A dozen or so products should probably be out by the first quarter, according to Avnera.
