The sound and the design of the speakers are excellent. What unfortunately not at stake is the fact that at rest a permanent noise is noticeable. The sound is actually very quiet, but still noticeable, and in the long run simply annoying. Because I want to use the speakers in combination with my PC which just does not continuously play music, a noise for me is intolerable. Here devil should urgently block a high end amplifier and strengthen the shield. Have played back the speaker.
