This wireless speaker has an excellent sleek design, compact and stylish. The build quality is clearly up to it. But that's not all: the excellent surprise is the sound quality, stunning enough for a device of this class. Nothing to say, the performance is there, and the sound is a more than satisfactory fidelity (faithfulness which certainly did nothing professional, but still very correct for the range which falls within the enclosure). I have not noticed adversely for Bluetooth wireless connection: it works wonderfully. But reluctant to wireless can also fall back on the jack or USB connection, which is more significant. It is also possible to adjust the treble and bass for a dedicated button. In short, it is a well designed product and almost perfect except for its price, in my opinion, could have been dropped by thirty euros (it is 159 when I speak). This is not a great but "simply" very good value for money. Purchase however recommend for those who have decided to put the money.
