As much admit right away, when I opened the box, I found myself in front of this object so light and not very big, I thought "I got conned" and not at all .. ... hop, I put in play a hip hop song with quite low and there I remained mouth wide open ..... !!!! What sound !!! For such a small object, it's just amazing!
This speaker myself everywhere, in the bathroom, gym, garage, evening with friends at the beach .... but happiness. The battery life is more than correct
