Bose has introduced the SoundTouch Wi-Fi music systems, offering a way to listen to music at home. They let you stream music wirelessly in any room.

Now, music from the web or your stored collection can be played with "lifelike clarity" by simply pressing a button, says Phil Hess, vice president of Bose Home Entertainment.

Three one-piece systems have debuted:

° The US$699 SoundTouch 30 Wi-Fi system measures approximately 10 x 17 x 7 inches. It features exclusive waveguide technology and a new proprietary woofer to deliver deep, rich sound and the power to serve as a home’s main music system, says Hess.

° The $399 SoundTouch 20 Wi-Fi system is more compact at about 7 x 12 x 4 inches. It can be placed almost anywhere.

° The $399 SoundTouch Portable Wi-Fi system combines full-range audio and a rechargeable, lithium-ion battery in a speaker no bigger than the average book -- about 6 x 10 x 3 inches.

SoundTouch Wi-Fi systems offer streaming music at the touch of a button, or an app for advanced functionality. They feature six presets on the system itself or the system’s included remote, and each can be personalized to an Internet radio station, music service channel, or stored playlist. Set a preset, and it only takes one press to your favorite songs.

The Bose SoundTouch app then lets you use your smartphone, tablet or computer for control. You can browse and discover content, operate any system in any room wirelessly, and combine all music services and stations with one look and feel. The new SoundTouch app is compatible with most Mac, iOS, and Windows systems.

Bose will also offer the SoundTouch controller, an accessory premium controller that works with any SoundTouch system. It features a circular design, volume dial and proximity sensor. All essential functions and information are integrated, including an OLED preset preview. The SoundTouch controller can be placed on a table, or on the wall using an included bracket.

For added flexibility, SoundTouch music systems are also AirPlay enabled, so owners can stream content from their iPad, iPhone, or iPod touch.
