Now I ordered the "Spare cables" or "Better cable" of Fiio, and I'm really happy. The cable is flexible. One could compare the cable from Fiio with a thin silicone tube. The housing for the plug is made of sturdy metal and painted Platinum Color. The plug is gold plated. The connections for the earphones are angled slightly and the small pins seated fixed in the terminals. Unlike the original cable here are missing the wires, which I find very good. One can simply lay the cable over the ear, and it fixes into place. Oh, before I forget, the cable is also slightly thicker than the original cable, but also robust. A sound enhancement or even worse and I can not find here.
I can only recommend the cable, it's really much, much better than the original cable, and for the price really worth it.
