Review on 6ft Optical Audio Cable - Suplong Digital Optical Audio Toslink Cable [24K Gold-Plated, Nylon Braided] Fiber Optic Cable for S/PDIF LG Samsung Sony Philips Sound Bar Smart TV Home Theater PS4 Xbox by Julie Brown

I have had a Kenwood surround sound receiver for 20 years and have never used an optical input. I just bought a new 4K TV and the only audio output was optical. Bought because of price and reviews. It works very well. I was impressed by the fact that when the frequencies are propagated by light, there is no interference from metal cables. I will definitely buy it again if I need a different optical cable.
