Unfortunately, the cable Balanced is structured and thus not usable for the above purpose, since the audio signals are not properly "routed". This results in an odd distorted sound.
Here emerges the term "symmetry" in the description to nowhere, so had to go due to the intended use of the assumption that it is an unbalanced cable.
Since there is only a quick fix:
Screw XLR connector and connect to pin 3 (soldering!) Pin 1 and you've got all the right signals.
Of course that's not the point of it all, that's why only one star.
