Boasting high-quality stereo sound, the sleek-looking, one-piece system contains four full-range speakers and an amplifier with volume controls. It's ready to use as soon as you slide a Sansa MP3 audio player into the recessed docking station and insert the attached connector cable into the player. Any source content on the Sansa, including FM radio stations, can be played through the speakers.

Although the Sansa Speaker Dock is custom-fitted for the Sansa series players, it has a rear input and comes with a three-foot audio cable that can be used with a variety of electronics devices. These include other MP3 players, portable CD and DVD players, portable game consoles and handheld computers -- essentially anything with a 3.5 mm stereo headphone output. Furthermore, the system can be hooked up to a PC -- using the included USB cable -- to transfer music and data to the Sansa player while connected to the Speaker Dock.
