I had to replace the cord for my HiFiman HE 350's I got from Massdrop. This cord is much higher quality and has a spring reinforced plug, along with it being nylon braided. Already better than the supplied cord. The audio quality is as high as any you would get from a supplier and fits perfectly in the jacks.
