I use the music ball mainly in the park and as a portable music in the house (as I do not have anywhere else music). Super sound and for the size of the part has real power !!! Think in the price and can be really Leisung Neither disappointed. Operate the ball with my Ipod, an mp3 stick or box on the PC .... you can see, the performance is convincing everywhere! Have two friends infected with the enthusiasm and thus I can also say that the interaction of several so-called buddies works beautifully and the sound of it and the Lautstätke naturally improved. The battery life is more than adequate, since most audio devices no longer have. (Ipod, ...) Have fun with it!
