I was very pleasantly surprised by this small speaker. Although the price does not give us the quality of its brands but the price quality ratio is correct. I would still have liked a button allowing me to acute low ratio because the way my bass is truly omnipotent and can have the gene see crush too acute. Full charge time of 2:00. Utilistation 5:00 during continuous (films and hands-free kit) and still ok. Instant connectivity. audible kit hands-free and easy to use, average build quality sup (except buttons that make toys). I did not put the max rating for 2 things: 1: No instruction in French and it annoys me and 2 charging cord and riquiqui, you need an extension cord to put it on the desk and plug it into my tower which lies at the foot of my office. No test on the max distance between the transmitter and receiver.
