I was positive surprised when I received these loudspeakers. The build quality is excellent, they are quite heavy for such a small speaker and well made. The loudspeaker terminals on the back are also of good quality, not made of plastic, but gold plated metal. Just as it should be. Speaker cables were inluded but very thin. These speakers are really extremely small (all sides as big as a CD or so), for those who like to hide them, it is possible.
It is possible to mount them flat against a wall with a small metal support, but I cannot adjust the angle, which is a pity. They are water resistant.
I like the reserved sound of this speaker. It sounds quiet, non intrusive, I think most music, also classical music sounds ok with them. The overall sound of the speaker is not very detailed. The low end is good for a speaker of this size, i did not have high bass expectations. Do not expect the quality of an expensive 2-way shelf speaker, I would say they are a nice background speaker, not a small monitor for concentrated listening. I will use them in a sauna. I compared them to a pair of 400 euro Tannoy R1 and the Tannoy sound is more clear. But if you want something very small and rigid, they are a good choice I think.
