PR Newswire (January 7, 2002)

LAS VEGAS, Jan 7, 2002 /PRNewswire via COMTEX/ -- As the world's first Digital
Wireless RF Headphones to transmit audio in true CD quality, Amphony is presenting
it's 2.4 GHz Digital Wireless Headphones, Model 1000 at this year's Consumer
Electronics Show (CES).

By using a proprietary technology, the 2.4 GHz Digital Wireless Headphones from
Amphony transmit audio in a digital format at a data rate of over 3 Million Bits per
Second (Mbps) from a stationary transmitter to one or more sets of portable
headphones.

"Since we transmit audio digitally, noise and audio distortion are absent from our
design which are the major drawbacks of existing 900 MHz analog systems," said
Gunter Fellbaum, marketing director for Amphony. "Further, since we can transmit at a
data rate of over 3 Mbps, we were able to avoid having to compress the audio which
would have resulted in audio degradation similar to MP3 compressed audio. In
addition, the high data rate allowed us to implement an intelligent error correction
scheme which is able to correct transmission errors to guarantee reliable error-free
reception even under difficult conditions."

The 2.4 GHz Digital Wireless Headphones are geared towards the medium and
high-end consumer as well as the audio professional. The Model 1000 2.4 GHz Digital
Wireless Headphones from Amphony have a suggested retail price of $129, and have
already started to ship to U.S. retailers.

"We are also offering a number of accessories to enhance the functionality of the
product," said Mr. Fellbaum. "By using RangeBooster modules, for example, a user
can increase the transmitter operating range almost indefinitely. Additional
headphones which can operate from the same transmitter are available as well."

Headquartered in Berlin, Germany, Amphony is a startup technology company
specializing in the development of electronic products and technologies, in particular
high-quality audio transmission technologies. Amphony products include consumer
as well as OEM products. In the U.S., Amphony products are sold by Amphony Corp.,
an affiliated Amphony company.
