Apart from the color too "flashy", this speaker is a powerhouse. Without excessive bass which certainly flatter the ear with some music but distort the balance, rendering is very "round" for a speaker of this volume. The USB socket for recharging a phone or tablet is very well come. Incredible as it may be, it advertises the sound of a video conference in a room of over 50 people, not ashamed of its performances.Un "perfect" product? no, because it would seem that the power outlet systematically through charging the internal battery and not by direct feeding. This feature would allow the semi portable use: far from the source sound to wireless yet fed a current source.
