Overall - quality is fine. Sound quality is not "monitor like", there is a gap in middle frequencies. But pretty nice to hear as ordinary speaker. Wooden construction adds some bases. Not very comfortable that woman chinese voice saying about switch between mode, is too loud, and cannot be decreased. I am afraid to turn this speaker in evening time. Have no choice, but to upgrade it and include mechanical stereo potentiometer. This is because electronic part (and speakers as well) are taken from cheap chinese bluetooth speaker HS-BT183, which is smaller in size, and probable sound level is expected to be less. This small devices cannot be used as mini cajon, because not enhanced with percussive springs. In general, its acceptable good speaker, wooden part is made with quality and care. I like how it looks - funny appearance. But overpriced a bit, because original donor speaker costs 10$.
