What a pleasant surprise: 16.5 cm long, 6 cm at the deepest point, the sound that comes out because of the black elegant little box is crystal clear and balanced, it has an audible bass. It's amazing that this quality in such a small space is technically possible. The volume is sufficient slack off for my 16 m² room. It remains to mention that the uses listed may (Bluetooth connection to the smartphone, Line-in, playing card and USB) function properly. When you turn on the device, you get an English announcement. The control panel is controlled by touch. The volume is regulated with a circular movement of the finger. The display lights up pleasantly. The reception power of the FM radio can be improved by the way, if you plug in the line-in cable into the device and expounds long.
