In the audio transmission so far I could not see any flaws. I had earlier in a temporary use (two cable together with adapter). Wanted to simplify and equal grow me a whole long cable. The cable is long and sound is good, but: The strong shielding the cable is very thick and very stiff. It is virtually impossible to get rid of the "embossed" type of winding. I conclude that the cable is intended for single shoring, not for frequent and stake. The cable is so stiff that any train immediately goes directly to the Ausgangsbruchse the audio source or the boxes on the cable. This is in the long run not good for the connections. Those looking for a long cable to set it once, to blind and does not have stuck around several times, for which the cable is super. For those simply looking for a long cable for playback from your smartphone or laptop, and possibly then briefly lying around the cable in the room, for this cable is not recommended!
