I have these boxes bought in mid-2014, and run this with a Creative sound card (Sound Blaster Z).
The sound is really 1A, also the boxes are stylistically with the best of what you can find in this price range, and so, the device can be seen, should also visually have a certain effect.
After about half a year, the hum went off, it was really annoying!
You could hear this sound through the entire (25 m²) room! So fix can call the Amazon support, and just held the phone to the pits, the staff just said, "is not at all yes". So get smoother Exchange, and the new boxes in which the hum has not occurred.
So now the state of satisfaction is again available, and yes, the boxes are for music, and very well suited to play, by the rich, but not too pushy bass!
Depending on the quality of the medium, which is taking place, the boxes can be really nice to turn up even without that appears somewhat distorted!
The shield is "ok", every now and then there is this typical "mobile hum", but this I have maybe 1 time a month, because I have a new mobile phone, which does not separate these radio waves, which leads to the typical disturbance.
Guess that it then is when the neighbor, or at the same adjacent tram.
Also worth noting that the boxes on a "rubber base" (just do not know the terminology) are, which is very important, and in this price range is not always the case.
But the ripple error is unacceptable when it occurs to!
If not the case, you get a technically good device, which is visually very successful!
