The speakers delivered today sound good. If no audio signal arrives (even if the line is in withdrawn plug), but you can hear a noise. According to it is not, but because the speaker with me very close to the monitor (and thus in my ears) are, but it bothers. Thus, the speakers go back again.
While the speaker previously used have been 10 years behind him and at that time were not very expensive, a comparably loud noise they have certainly never given on its own.
Apart from the fact that both B20 are good. Who does not sit so close to the speakers will probably be able to live with the noise. Also it depends on the Lautsärke set on the speakers themselves. If the controller is set as low as possible, even the noise is quieter.
Here I'll give you 3 points, without the noise it would be. 5
