I bought this extension for my Logitech Surrounds X-530 to get in the hope of Hama acceptable for the price performance. The first thing I noticed when I had joined it, was nothing. Enormous volume loss, I heard nothing. So a bit of messing around at the sound card output for Surrounds connected to the cable set to 100%, everything else down to 60%, which evens out about. When I was able to hear anything I put NEN tight astringent quality loss. The heights are completely absent. The fact that you can use them well, if you change the performance, there is of me 2 stars, but more really is not, due to the astringent quality loss. One can therefore quite even watch DVDs in 5.1 and enjoy, as long as you do not have high expectations, but as a bitter aftertaste remains after all.
