I was skeptical, but had the sound of my old low budget boxing really tired. The small black box has at mp3 music and when streaming, only 3.5-jack cable because of the small time delay in Bluetooth, pleasantly voluminous sound. We use the part of trays (Sony, Acer, Asus) and mobile phones at different places, but it is the optimal solution. The NFC works, the battery lasts at least 4 hours. It rattles and roars nothing, the volume is more than sufficient. Who is not expected highend sound very well served by the small vibrating black square.
