I am really satisfied with this product. It's affordable, lightweight and non-complicated. And it has no background noise. It's really quiet!
I like that it has all connections in the front so that you don't risk setting it down on the connector cable, damaging the connections.
It also has EQ and volume control if for any reason you would like to have more treble, mid or bass. But it should be said that "set to flat" the sound is great. The controls are easy to understand and easy to use.
I tried connecting it to an in-ear-monitor I have and that sound is equally great.
If I have to think of a minus it would be that it doesn't have a handle for carrying.
