What mattered more to me was to find a compact loudspeaker to connect it into your notebook. The built-in computer speakers are indeed ok, but if the source sounds washed out, or it is word about contributions with spoken translations, it quickly becomes tiring.
This small, round, 9 x 4 cm small speakers surprised me sound technically. I would have given him credit for his performance not so. Of course one must not expect miracles, but the notebook he brings me a clear improvement.
Furthermore, I have connected the speakers to different mp3 players and was pleasantly surprised because of the sound. To my mind it sounds fairly balanced, may be that it is a bit weak bass, but mids and highs come through well.
Also, I have carried out with several people "blind dates". I have the speakers powered by different sources and awaited the reaction of the people. Every time I harvested quizzical looks, where the noise was coming, and when I let the cat out of the bag, I was appreciative approval, that the sound but would be quite good.
The Lausprecher has its own volume control, and has a further connection to connect an additional speaker can. It is loaded with the help of a USB cable to the laptop / PC.
It may be that it perhaps even better is for smaller money, but from a purely technical demands here, I am very happy with this mini speaker.
