he SanDisk Sansa Shaker features a simple, kid-friendly design and will be available in a variety of colors. The player is half-toy and shuffles up music when shaken. Fun sound effects when the player is paused or turned on and off add to its appeal. It’s inexpensive and includes an external speaker and two headphone jacks for sharing. Sansa Reviews says however, The flap covering the ports on the bottom of the Shaker may not be durable over time, and the lack of rechargeable battery may not appeal to everyone. The player only supports MP3s.
