It Literally turns ANYTHING into a Speaker!!Yes, we are serious!!!!It may look like a plain boring circle charm at first. But if you open it up, plug in the cord into your MP3 player, then attach the charm onto anything (solid) around you, it turns into a speaker!!Brand New Concept that is Going to Revolutionalize the World!!All you need to do is open up the charm in half. The speaker is going to stick onto whatever you would like to turn into a speaker! The sound is caused by the frequent vibration inside of the speaker. It is so amazing it may very well change the history of the way people listen to music!!!!China supplier:Email : fangzhengcn@hotmail.com Skype ID : chanceller819
