The processing is eig. Quite good but what bothers me is that the jack apparently does not handle well is resulting noise to a very very very quiet whom no music runs .Ansonsten they have ne good sound quality and the bass is also super for as little boxes. In addition yet they are compact and hence take away not a lot of space and you can taken anywhere. Some want to use these boxes with a smartphone or car, should still buy an extra adapter for USB. The there is at Amazon for a few euros.
