At first I was pleasantly surprised by the, for such small boxes, good sound. Especially the weak otherwise without subwoofer depths come over pretty good.
Unfortunately, the good impression clouded soon as I realized that the sound to the image of the video or TV signal was not completely synchronized. This may strike some may not even notice, just when the delivery is fast, I found it very disturbing.
If the boxes used mainly for playing music, I give a strong buy recommendation. For the size you get a good sound, and connecting via Bluetooth is very easy.
If you want, however, also see videos, you have to either accept the asynchrony or intervenes as I prefer to speakers with USB or jack plug.
