The sound quality is quite correct: it lacks a little bass and treble are not of great finesse, but the whole medium is partly restored. at first listen, one can also find it lacks power, but in practice it is quite enough for a standard size room.
I like the ring that allows to hang it to a bag or elsewhere and the rubber sheath is easily removable, convenient to clean a speaker that would have taken sand, mud, or simply dust.
The price below 30 euros is perfectly justified by the benefits, and vice versa: the benefits are related to the price .. very honest.
