Quality microphones correct, but I recommend using an amp Roland electroacoustic to round the sharp sound somewhat, quickly tiring to the ears ...
Channel okay, but do not expect accuracy in the treble is too much to ask at this price ...

UTILIZATION

Channel pleasant enough, but access to high notes is only theoretical ...
Ergonomics satisfactory, despite a poorly placed jack, the instrument this good, the finish is honorable.

SOUNDS

The serious (it is relative ...) are correct, but the treble, though brilliant, are generally wrong ...

OVERALL OPINION

I use it on stage for several months, it is very suitable for home and rehearsals, but do not use it on stage because it goes out of tune very quickly (I had to replace it with a more reliable applause) .
The price / quality ratio is very convenient, but do not ask him what he can not offer you ...
