TISOFU [Ultra Certified] 8K HDMI Cable 6FT: HDMI 2.1 Cables 48Gbps High Speed Premium Braided Cord 8K@60Hz 4K@120Hz 4K@144Hz HDCP 2.2&2.3 CL3 ARC eARC for HD/HDR/HDTV

Certification is valid. Solid looking cable. Not hooked up yet. Will update after connecting to my equipment.

A better idea to get 2.1 cable even if you dont need it. If you ever update your system you will not have to get new cables. A wise investment. System is a 4k TV and PC Nivida RTX 3060. All set for any future needs.

Ive had a lot of trouble finding a cable that works reliably with ARC. Hopefully this lasts longer than a few months

Solid cables, well-made and no issues.

Great difference on video and audio quality highly recommended.

Trying to get eArc to work on Sonos Arc and this did it with a Samsung QN90A. Not sure how but it wasn’t working and now it is!

Quality is good for what you pay for.

Cable looks to have very good build quality and worked as it should.

Even on a 1080p Monitor or TV, I see a noticeable improvement. First time thats happened! (Note: This is with a 6 ft. cable - your mileage may vary with a longer length.) Also, these cables seem to be very well made, with good shielding. I really like the braided outside cover - doesnt catch on anything, but is still reasonably flexible. The jacks, also, are gold plated with casings that are small enough to fit into tight spaces. I would definitely buy this brand again.

Great product worth buying the picture is crisp and clear and you can hear the difference in the sound I got this cord for my 4k tv and I have a Dolby atmos sound bar also and it is compatible with bith and works great no complaints here I even bought another one for my 4k dvd player
