What a pleasant surprise, this colorful little polyurethane sponge ball is actually a portable speaker! Simply insert the mini plug into any MP3 player's earphone jack to serve up quality sound. Comes with an audio cable and a USB cable for charging the built in lithium-ion battery. A 2 hour charge will last for over 4 hours at maximum volume.
