Here's a tiny solution to playing your personal MP3 player for others; a small powered speaker cube! Barely 1.25" square on the face, this little unit has its own built-in Li-Ion battery, easily and quickly charged by plugging into the USB port on your computer with the included adapter!
Simply turn it on, plug it into your MP3 player (or FM radio, or any personal audio device with a standard headphone jack) and listen away! Comes with not only the USB charging adapter, but also includes a small 12" audio extension cable!
This is the perfect speaker solution that fits in your pocket or purse!
