We are far from the quality of the bluetooth speaker Bose, but it is also far from their price! (Less than a quarter) Honestly, the sound is not great, but for 39 euros, quite correct. The enclosure works well, bluetooth fashion as fashion filiaire (cable included to connect the smartphone or tablet). It was detected on my smartphone. I enjoyed the + and - buttons on the side of the enclosure, to change music or adjust the sound without touching the smartphone. There is also a "phone" button to take or reject a call. In short, for the price, everything is pretty much done, I recommend!
