So far so good. If you want to be thinking anyway, because with 25 purchase price, this is one no longer favorable to the devices on the segment, so it should but also hammer out the sound properly. That works quite well as long as you do not want to hear very quiet. Because then reveals an unmistakable, unpleasant noise. And so strong that it clearly limits the listening experience when I have come to rest and the evening would like to hear a bit of quiet music. By the way, so strong that I ausstöpsle the headphones when I hear nothing in between times. Big minus.
The line-in I have not tested. The four-pin socket is Geschackssache, but I believe contributes to the compactness of the device and with an adapter is included. Therefore small plus.
In the end I can say that I will stay with this sound card only, unless I find one with a similar design, but with no noise. Nevertheless, there are two star deduction for noise. If you do not want to hear quiet it is a very good card, otherwise not.
