SanDisk has unveiled a new MP3 player designed for kids . Called “Sansa Shaker”, the unique and curiously shaped music player includes two headphone jacks, a built-in speaker to listen without ear buds, and the ability to play SD cards. Changing songs on the player is a snap, or rather a shake. Young music lovers can impress their friends by shaking the device to jump to another song, or use a simple controller band for moving forward and back through their song library, and a second band to control volume.

“Sansa Shaker brings a fresh approach to sharing and enjoying digital music, at a price that’s affordable for everyone in the family,” said Keith Washo, SanDisk retail product marketing manager. “This is part of SanDisk’s continuing strategy of introducing MP3 players for every lifestyle, with a wide range of features and price points.”

The Sansa Shaker is available in pink and blue, and it comes equipped with a USB cable, lanyard, five pre-loaded songs, and a colorful array of stickers so kids can customize their device.

The Sansa Shaker also includes an AAA battery that allows up to 15 hours of battery life (based on continuous playback at 128 kbps MP3 file) when using a single pair of headphones. It also comes with a 512MB SD flash memory card which holds up to 125 MP3 songs.

The standard SD card slot makes it easy for kids and families to swap out flash memory cards loaded with a variety of music, an especially helpful feature for families that already have MP3 collections.

The Shaker is expected to be available in the United States in late April at a manufacturer’s suggested retail price of $39.99, with availability planned in other parts of the world later this year.
