Case 4 ur cell phone, amplifies ur music.

This has also yet to used... but it works Great!! Holds UR cell phone ND gives U a wire to connect it to the spekers.. it's hard case, in case you drop it ND it zippers around the entire case... you can use the ckio to Clip in your car, shorts when jogging, just let be as a speaker etc.. totally amplifies your music on you cell phone ND is basically a speaker for the music on UR phone plus protects it with it's hard case!!
