For the price and the size, the sound is great and I must say I'm very happy with the speaker. One of the first things I did was to drop it from roof height. The front net came off and the speaker went dead silent so I thought I broke it. But it only landed on the play/pause button.
One thing I don't like, tough, is the default sound when turning ON and OFF is ridiculously loud. I'd be perfectly satisfied with the product if that would be changeable (if it is and I just don't know how to do, you are more than welcome to teach me).
