This is the wireless speaker system that transmits music from an iPod (or another audio source) to remote speakers located anywhere in your home or outdoors up to 150′ away, five times the range of similar devices that rely on Bluetooth transmissions. It uses FHDSS technology, a communications algorithm that will not interfere with WiFi networks or cordless telephones, and unlike Bluetooth or analog signals that mute or produce static in response to poor signals, the unit automatically corrects signal errors to prevent sound distortion or impedance. A patented technology developed from years of psychoacoustic research restores original audio data lost during compression of digital music files, a common characteristic of many iPod music file formats, resulting in CD-quality sound.
