Box top, cable defective

I have these mini Speaker ordered by the lake or in small rooms (caravans) to be able to play music with the smartphone. This task is done automatically with flying colors! Standard laptop speakers or smartphone speakers have no chance against this Part, both in terms of the level and the frequency response. Of course we must not experience wonder at such a battery powered mini-range drivers, but it is enough for its purpose. The sound is surprisingly good radiated in all directions in the open even though the membrane facing upward.
To save battery, I recommend the player to turn on full power and the box is only to the level required of, because the box is safe from the player all. The transfer via Bluetooth or via jack cable works without problems.

Why do I still forgive only four stars? The supplied jack cable was broken, his own work immediately.
