HDMI 2.1 Coupler

I needed longer HDMI runs but wanted to use my existing cables. These are perfect for turning my 6ft cables into 12! I haven't tried these couplers at HDMI 2.1 speeds as I have no 8k panels nor anything that supports 4k north of 60Hz. That said, they're fine with 2x 6ft cables running 4k @ 60Hz.

Perfect adapters

It did the job and It works really good and has value for the money and the connectivity is great as well :)

I use these type of couplers often in my line of work. HDMI cables need to be coupled and uncoupled for temporary setups or for TVs on a patio at a restaurant every day. These particular couplers are the best I've found so far. Good price, very good snug fit, and 100% reliability so far. I also like the blue color detail. EDIT: These promised better performance at first. Now, they are just like any other cheap coupler. 50% failure rate.

Hisense 72"U7; billions of cores but 1st gen amd processor, 32g mem, RX 5700 XT w 3 shot HDMIs, Benfei DP->HDMI adapter 6' w 5v/1a usb power, Adauxter 3' extension hdmi, coupler, same specs across all components; crossed fingers after living with a horrible anemic Sony 85" for too long: 165hz from windows to Hisense with zero issues, pic went from underwater to exploding with color and brightness. Nothing but trouble and sacrifices with earlier adapters ($7 to $100) and hdmi "high" speed cables, just 4k 60hz static Sony-pretend HDR. No idea about earc, but that's a DP issue; if it doesn't work it's not these cables/adapter.

These couplers worked flawlessly to extend my HDMI 2.1 cable for 8K video. No signal degradation, even during high-frame-rate gaming. A compact, effective solution for tight AV setups.

Great price fast delivery nice simple find

I keep losing connection between my devices and the tv. I know both cables are good so it has to be these connectors. REVISED: After upgrading to quality cables and making the connection closer to the tv and away from the media player. I was able to get these devices to work correctly. They have been in service for over a month with no issues.

I bought this 2 pack for when my family and I go out of town and we use out laptops to project on the hotel's Smart TVs via HDMI. The problem I had was connecting a laptop to the TV and then changing the streaming device to my Firestick. I hated going around the back of TV with limited space and swapping out the cable. This way I can just plug in just 1 HDMI cable just once and use these coupler to switch between laptops and Firestick 4K with convenience and ease. It's backwards compatibile too because speeds of devices. It just works on all our mentioned devices.

Ich benutze die HDMI Kupplung um die Verbindung von der PS5 und die XBOX X an meinen OLED Monitor zu verlängern. Vorher hat ich von einem anderen Hersteller die Kupplung gehabt. Es gab ständig Aussetzer, Verbindung brach ab und kam nach 2 Sekunden. Mit dem Artikel hier passiert das nicht mehr. Kann ich nur empfehlen.

Not much to say, work exactly as expected and the cheapest ones available!
