Cable of very poor quality and not isolated static electricity, purchased with a digital audio converter, it parasitized sound disseminating "pops" from time to time, I thought it came from the converter, I then changed .. . for nothing! and also this cable enfichait very badly in the new converter !!! I then tested another cable "armored" (commercially purchased) and there, no problem! So I made the new converter, reinstalled mine and threw the Amazon cable in the garbage ... if you have a concern of his kind with a digital converter parasites, slamming his strange, remember to check the quality of the optical cable and / or coaxial before replacing a converter that there may be for nothing! Content Amazon for the quality of its products, I do not think anytime soon renew this kind of purchase via the website ... very very disappointed !!!
