I do not know if I simply just get a defective item, or the speaker should really be quiet. I have it connected to your smartphone and it was hard to understand something, so I tried it on a stereo system and also because they were very quiet.
I'm going to solder it new speakers and to fix it, hopefully. What I do not understand is also the connectors used between speakers and jack, intuitive unfortunately this can not be connected.
More than a star I can not forgive, unfortunately.
