Well, does what it is supposed

I have to say the same anticipate why I Kabelmeister audio / 3.5mm jack extension cable 0.5m have purchased my earphones go unfortunately (for a long time differently) broken, the cause always possible to a defective cable near the cable beginning find (audio device close). Therefore I am. For a cheap, short, looked cable extension, which should replace this route exactly, so that the headphones are not for some time to redeem / throw away, but a cable that costs a few euros A cable (not this one) I've used, so the plan seems to be working.
For this reason, I am assuming that this cable is defective, sooner or later, I think these expectations should I say in the review, therefore.

For cable: Processing seems slightly better than satisfactory, an audio cable can be connected only with a little more pressure. The audio signal is transmitted well in my opinion, I see no difference with / without the extension. It now works for several weeks without any problems, as there is nothing to complain about.
So for the price it was a good performance.

The final impression will, of course depend on how long it holds and whether the price / performance ratio then agrees. If it breaks following an update.
