ok i ordered these speakers to use in a project and i seen the reviews saying that it was kinda quiet. that is the UNDERSTATMENT of the freakin century. these speakers are rated at 8 ohms at 2 X 1 watts... for anyone who doesnt understand what that means... it means they give off next to no sound at all. it seems like they put no thought into these speakers at all as far as sound quality and volume it say no batteries are required but for these type of portable speakers, they really would be necessary. overall i am not satisied at all and i would not recomend these i would get battery powered speakers or some sort of portable dock... dont get these because they are a waste of your money and i also forgot to mention that they are freakin HUGE!!!! they are like a softball or a grapefruit cut in half.
