Overpriced cheap cables

I wanted to use this cable in my MP3 player with my stereo system to connect, but unfortunately I had to realize that does not work the left channel. The error was found rather quickly: solder joint on the left RCA plug. Looked as if a three year old playing with a soldering iron, burned insulation, too much solder and in the form of drops on the cable. The contact point at the plug was heavily oxidized.
Out of curiosity, I've sometimes the other solder joints looked and they were not much better. At almost all solder joints, I found "cold" solder joints before (with aussnahme of Ground Connection at plug jack, here was worked reasonably decent). Thus, I have not even done the work to measure the Habel order to be able to compare me with others.

I usually speak again the people are of the opinion you have to spend a lot of money for cable, the expensive sound supposedly better. However, Wen, take this cable as a basis for comparison has said group but apparently not so wrong.
