The Magic Bullet speaker is a very small, mainly round, circular like object.
It can even pop up to enhance the depth of sound quality some what. Just expand the retractable cable and plug in to any standard headphone port and your ready to listen.
I got it at Walmart for around $15. It comes with a micro USB charging cable.
This small portable speaker produces very nice sound for its size. It can play content louder than the built-in speakers of iPhones and iPods.
The rechargeable battery lasts up to 7 hours according to the instructions on the box.
I rather enjoy this little gadget, and plan to take it on trips with me in the car. It also can serve as a very nice loud speaker phone for calls with no feedback.
