It's not a bird, a plane, Superman or even merely an adorable little Batman figure - the Batman Pop Audio USB/MP3 Portable Speaker is a tiny portable speaker designed for your computer, mp3 player or i-Device! That's right, this 4" high Caped Crusader features a speaker right in his noggin from which you can hear your favorite music, podcasts, etc. When turned on and charging, the light on the back of Batman's head will be red, but while rocking the block with your tunes, the light turns green. The Batman Pop Audio USB/MP3 Portable Speaker features a dual USB/3.5mm adapter, the latter tip of which should fit most headphone jacks. When you're ready to rock the Batcave, plug Batman into the device of your choice and let him handle the rest...at least as much as a 4" figure with a speaker in the back of his head can handle!
