SONOS INTRODUCES THE SONOS ZONEPLAYER ZP80

ZP80 Makes Existing Audio Devices Part of a Wireless, Multi-Room Digital
Music System

SANTA BARBARA, Calif. — January 4, 2006 — Sonos, Inc., the developer of
wireless multi-room music systems for the digital home, today introduced a
new ZonePlayer to complement the Sonos Digital Music System suite of
products. The Sonos ZonePlayer ZP80 allows music lovers to play all their
digital music, all over their house, on all of their favorite audio
equipment — a home theater system, powered speakers, a premium table top
radio such as a Bose Wave Radio, and more.

By connecting a ZP80 to any amplified audio device via the analog or
digital outputs, that device instantly and seamlessly becomes part of a
wireless, multi-room digital music system. This provides the consumer with
the power to use the full-color Sonos Controller to control all of their
music, in all of their rooms, all from the palm of their hand.

“We created the ZP80 because many of the rooms where consumers want to
listen to digital music already have an amplifier,” said John MacFarlane,
chief executive officer, Sonos, Inc. “Our goal is to provide digital music
lovers with a range of products for building a wireless digital music
system throughout their homes.”

The ZP80 can also be used to retrofit a conventional multi-room audio
system with home-run speakers or as a wireless extender to increase the
wireless range of Sonosnet, the peer-to-peer wireless mesh network created
by Sonos.

As with the Sonos ZonePlayer ZP100, the ZP80 includes auto-sensing line-in
connectors that can digitally encode any line-in source. This provides
Sonos users with the ability to connect an external audio source, such as
an Apple iPod, a CD player or satellite radio, to the Sonos Digital Music
System and to listen to that source throughout their home.

The Sonos ZonePlayer ZP80 will ship in Spring 2006. The ZP80 will retail
for $349.00 / =A4399.00 (including VAT) / =A3269.00 (including VAT). The n=
ew
ZonePlayer will be available at Sonos authorized retailers worldwide and
directly from Sonos at (http://www.sonos.com/)www.sonos.com.
