I now have bought me this part, on the recommendation of a friend.
I had expected nothing really.
Unpacked and ... oh jee ... much smaller than ever imagined.
This may actually be nothing.
So completely as expected free USB and Line-cable plugged into the PC, dice turned on and the radio angeschmissen.
AMAZED !!!
This little thing makes an incredible ruckus.
Crystal-clear highs, still good midrange.
For now phased sometimes loud music listening on the PC can be the part does not rotate so loud, until it starts to distort.
I enjoy listening to Dudelfunk and sometimes Goa trance fuss. In the latter, the device brings the sounds super crisp over without having to "verbrabbeln" or to roar like cheap PC speakers.
Actually I wanted to pull the device a point, because it says "Bass" -Cube.
Well ... ahem ... and bass arising now time through resonant space and mass.
This grabs the part, of course not, how could it because the well?
Nevertheless, it sounds pithy.
And for the money, it is a pure surprise and the money well worth it.
I can about the functions with inserted micro SD card not say anything, I did not try and I will probably not use. My friend says he can not before the MP3 songs and rewind at his dice.
Oh, and ... if you turn off your PC, then turn the cubes or it is empty the next day.
And then there until he partially charged some ugly crackling is when listening to music.
From me and for my kind of use a strong buy recommendation.
