Cables look good and I connect several "free" sources to my home theater such as MP3 players, cell phones and a few other devices. My Firestick has always annoyed me with noises. when he was near those input wires. The old cable was not shielded at all. There is no difference in the hum of this "shielded" cable compared to unshielded cables. Disabling the firestick solves the problem, but I prefer to leave it on for updates etc.
