I am back after 1 year to update my review as I recently got new 4K cables. Now I have something to compare. Let's just say my new cables are like an exploration of sound versus monster cables. I used these cables in my Atmos system. These cables don't even come close to rendering video or audio that my system can handle. At first I thought it was my Atmos system. With new cables I'm in the cinema. With those cables I felt like I was watching a movie across the street, everything sounded boring. I hear a lot more with my new cables than with these old cables. Don't waste money.
