Used with a mini S5 for outdoor music workout and nothing to say. The packaging is at the top, the connection is instantaneous, autonomy is royal, the quality of the sound at the top (after bass enhancement on the phone), power is important and there is a little room before reach the maximum sound level. Otherwise, the speaker system is red but strangely all outlet / USB cable is "yellow neon green". Who knows why ...? A red equipment identical to the enclosure (or just white) have been more appropriate.
