Actually quite a good speaker. Slight noise, but if it is turned bearable. Since there are very different "noise generators") In my view, the price Leistungeverhältnis is very good! Fits perfectly with the current Dell monitors, operate it on a Dell UP2414Q. Unfortunately, he was broken after a day - the right channel was dead. Exchange is on the way ... if necessary. I raise to 4 stars, when the survived longer new;)
