Review on 🔌 SIKAI MOSHOU Ultra High Speed HDMI 2.1 Cable 8K 60Hz, 4K 120Hz, 3D Ultra HDR 48Gbps HiFi eARC Dolby Atmos HDCP2.2 HDMI Cable Compatible with Samsung QLED 8K Q900 TV, TCL Roku TV, VIZIO TV (15 Feet): High-Performance Connectivity for Immersive Home Entertainment by Anthony Jagers

I had a high speed HDMI cable and upgraded my soundbar. Keep getting out of sync with videos even though they weren't that long. I went to my cable box and you really can't tell how much bandwidth a cable labeled "high speed" can offer. I decided to use these cables after reading the specs, not sure if they could handle the max; but they should at least have been able to handle my 4K with 7.1.2 audio running through my sync box. I'm happy to report that they're doing it flawlessly. I had no audio or video snippets and can really enjoy my screen time.
