As might be expected, the sound is not very clear. This I can fortunately through my sound card (prof. Equalizer) compensate, though only partially. You can tell it anyway (especially @ high volume).
In addition, the cable length of the small boxes is not particularly large. There is just enough time to draw up the rear speakers behind the desk. Who makes these parts into his living room, has guaranteed no 5.1 sound field.
All in all, the sound system while the 50 value, but that's it. They are not suitable for high-quality sound enjoyment in 3D home theater experience or in PlanetSide Universe II computer. Who does not need a lot and otherwise has no high demands on sound, for those that are just the right boxes.
