Very good sound, robust, cheap.

I have purchased the product for about 10, so it is the hitherto best compact speakers that I have acquired. I own several, more compact speaker (with and without BT) with similar size and a similar form factor. Compared with these mini-speakers MusicMan, Easy Acc and various No Name brands China offers these speakers, for my taste, so far the best sound in music (in film sound less), both indoors and outdoors.

The music sounds like it subjectively even better than my larger, wired devices from Logitech (Z305 and Tablet Speaker for iPad). The distortion possible maximum level comes naturally not to the two Logitech Speaker ran, but is still quite high for the housing volume. But I like the sound better in terms of linearity / information transparency. He sounds very harmonious for me, because it does not sound too neutral but not too bass or treble-heavy.

Despite the design-related, problematic locatability / orientation to the Speaker nor proven even when watching film sufficiently well.

The BT-range I would describe as average, the BT-operation has hitherto been possible with all my equipment. The battery power when using the BT function unfortunately quite quickly tired. After five or six hours it's over.

Enjoyed how rugged the unit. When used on various construction sites he is me several times from up to 2 meters height fallen despite the rubberized footprint on stone floors (wind) without going broke. Once the mesh cage cover was levered out through the driver by the fall; this could be but easily Reinsert. The sound and the BT receiver have not suffered. The surface is fairly scratch-resistant. The device also easy to clean because it has no unfavorable to-reach crevices / openings.
