Optical OK Acoustically a compromise

The price, the compact design and the visual effect with the illuminated feet are nice. Listen to audio books and maybe soft music going quite well.
However, should boxes according to my understanding have especially an annnehmbaren sound. But precisely because it lacks much in these boxes. Music or video
a little louder to hear; eg on a notebook you should not try definitely. Distort the boxes and provide neither the high and certainly not the low notes.
The slightly larger boxes from Logitech are there much better. For EUR 10 it would provide a compromise. Acoustically no good.
