Here is a bit more than a week I test the sound system. I took it to replace a 5.1 system in Logitech because I find it too imposing and use 2.1 loses power. Level sound quality no complaints, it's low, the bass box is very average, if not nonexistent. But overall given the price and it is quite correct. However there is a big downside: after 5 minutes without music around the system seems to be to "sleep" by making a loud noise. At the beginning we said we can live with, but no, the noise and come back even if we launch anything in music. The return of the sound is also laborious, it can happen after 20 seconds of playback if the sound is too low. For someone who listens to music continuously is perfect (and again) but for a versatile person (word processing, video editing etc ...) it may soon become boring. All that to say that I have a lot better with my logitech system, which I am eager to reconnect, even set to 2.1.
