Another copy now works without the problems mentioned. The sound is much better than expected, without the existing of many speaker sets "sound beautification" - ie lack of middle. Size Because one must of course not expect too much from the basses.
Another advantage is the wiring. If the appropriate Dell monitor is connected via DisplayPort or HDMI, so it is, provided an appropriate graphics card, the audio signal for the speaker. So you have wired supply and signal from the bar to the monitor. Contrary to other reviews works for me also the volume control on the computer.
Benefits:
Surprisingly good sound for the size
Simple wiring
Space saving on desk
Disadvantages:
Obviously, you can sometimes get a bad copy.
Sensitive souls can the on-light interfere behind the speaker grille, especially in a darkened room.
Conclusion:
I would the bar at any time to buy back, for me it is much better than the same expensive speaker systems from other manufacturers.
