It's unbelievable what's inside the box. For the price, really good sound. We use the system for dance rehearsals. This is really fun. The mics are good for Hobbie-use. For announcements of festivals, absolutely sufficient for the samples. Clear wonder you can not expect it. But that's better than any megaphone all and the mics are only a added great ad on. The USB Player works flawlessly. What bothers me is only partly that the good thing losdudelt as soon as you plug in the drive. The remote control is Mini. I'm curious times when we lose. And really stupid it is that you if you stand in front of the box can totally forget the remote is. Too bad. But still there is of me 5 stars, because we are talking about a box under the 300th I have not found better comparable.
