Logitech has announced three new wireless products built around the proprietary Logitech Music Anywhere technology, which streams music from a PC or portable music player to a home stereo. The Music Anywhere system uses adaptive frequency hopping to avoid interfering with existing wireless services, and, since it doesn't use 802.11 frequencies, can't be used for other home-networking purposes.

The first product, the Logitech Wireless Music System for PC, streams music from users' computers to connected home entertainment systems within a range of about 300 feet. The three-piece system includes a wireless transmitter that connects to a PC via USB, a wireless receiver that connects to a home stereo receiver via RCA or 3.5 mm jack, and an infrared remote control.

The remote is used to control the PC's music playback, and can also be used from another room. Logitech says the remote control is compatible with iTunes, WinAmp, Windows Media Player, RealPlayer, and MusicMatch.

The Logitech Wireless Music System for PC will be available in September for $149.99 .

Logitech's Wireless Music System for iPod does the same thing as the PC system, but connects to any portable music player through the headphone port and has a range of about 30 feet. The Wireless Music System for iPod will be available in October for $149.99 .

Lastly, Logitech has also built the proprietary wireless technology into the new Wireless Headphones for PC. The headphones have the same wireless receiver built in, and connect to the PC via USB with a claimed range of 165 feet. The headphones will be available in October for $129.99 .
