Audio is catastrophic, are much too low, do not even represent its true that listening. Most of these small boxes are boosted from the factory is very low false horrible messy, lack of precision even with a considerable Eq .. Notice refers to the use of Eq Itunes ... it's worse ... not to disturb its neighbors must be cut at least up to 250kHz which distorts the sound and makes it even more horrible ...

Even for 30 euros I would do not have that choice ... heads of ways the price speaks volumes about the quality ...
