Bought this with the intention to replace my headphone wires, when they would break, but that hasn't yet happened.
So I made an extension using this cable, Rean NYS 231 L and Rean NYS 240 L jacks. And it works great, using the shielding as the ground.
This wire fits nicely in those jacks, easily takes solder and overfall feels very solid.
I am very happy about this.
