Stouchi 8K HDMI Cord (48Gbps, 1ft) for 4K@120Hz, 8K@60Hz, eARC, HDCP 2.2/2.3
Product description
The essentials
If you’re trying to get the most out of a modern HDMI 2.1 setup—especially for gaming or newer media devices—this Stouchi 8K HDMI cord is built around high bandwidth and the features people actually look for. On paper, it’s aimed at support for formats like 4K@120Hz and 8K@60Hz, plus eARC and modern HDR/audio standards. That’s the kind of spec sheet most people shop for when they want fewer compromises: less handshake hassle, less lag, and audio/video that can keep up with demanding sources.
It’s also a short cable (1ft), so the main practical benefit is simplicity. A short run is easier to route cleanly behind a TV stand or between a console and a nearby port, and you generally avoid extra slack where connectors can get tugged.
That said, HDMI 2.1 performance doesn’t live in the cable alone. If your source and display don’t support the specific refresh rate/HDR/audio mode you’re chasing, you may not see the full result—cables can only do so much.
Key features that matter in real use
The cable is described as a 48Gbps “Ultra High Speed” HDMI that follows HDMI 2.1a, with support listed for 4K@120Hz, 8K@60Hz, and 2K@144Hz. For gaming, those refresh-rate numbers are the headline, because they align with smoother motion and fast response modes.
On the home-theater side, it includes eARC and compatibility with advanced audio tech like DTS:X and Dolby Atmos (as stated). If you use a soundbar or receiver and want audio formats to pass properly, eARC support is one of those features that can save you from “why is it only sending stereo?” headaches.
For video experience, the listing calls out support for features such as SBTM, VRR, QMS, and ALLM. These are the kinds of HDMI 2.1 features that can help with things like reducing screen tearing/stuttering and enabling a more game-friendly display mode (again, assuming your TV and console actually support those modes).
What you’ll notice day to day
In everyday terms, this cable is positioned to help when you’re sensitive to performance details: quick switching, less lag, and fewer display hiccups when you move between apps and game mode. For example, if you power on your PS5 and it swaps video modes between menus and gameplay, QMS and ALLM support (per the listing) is the sort of thing that can reduce noticeable interruptions.
For media, eARC support plus HDR/audio compatibility can matter when you want your TV to delegate audio correctly to a sound system without manual workarounds.

Compatibility & requirements
This HDMI cable is advertised as compatible with a wide set of devices, including PS5/PS4, Apple TV 4K, Roku TV (as mentioned in the product name), Blu-ray players, monitors, PCs, and sound systems. It also calls out compatibility with 2023 MacBook Pro 14"/16" models with Apple M3-family chips.
Keep in mind a key limitation from the listing: achieving certain high-end modes (specifically 10K@30Hz and 8K@60Hz) may depend on both the HDMI source and the display supporting DSC (Display Stream Compression) under the HDMI 2.1 specification. In other words, the cable is ready, but your chain has to be too.
Where it shines vs. when to skip it
This is a sensible pick if you’re building around a modern HDMI 2.1 setup where you care about 4K@120Hz gaming, up-to-date HDR behavior, and eARC audio to a receiver/soundbar—especially with a short physical distance.
It may not be the best match if: - You don’t need HDMI 2.1 features and you only watch/play at lower refresh rates. - Your components can’t support the refresh/HDR/audio modes you’re expecting (then you won’t see the advertised benefits). - You actually need a longer run—this one is only 1ft, so routing may be tight depending on your setup.
Should you buy it?
Worth considering if you want a short HDMI 2.1a cable built for high bandwidth (48Gbps), eARC audio, and modern gaming-focused behaviors like VRR/ALLM—provided your TV, console, and audio gear support those modes. It’s the kind of cable that makes sense when your current connection is limiting performance or you’re setting up a new device chain.
Better avoided if your setup is older and you’re not chasing 4K@120Hz/8K-era features, or if you need more reach than a 1ft cable gives you. Also, don’t assume the highest-resolution refresh numbers will automatically show up—this listing itself notes that some modes depend on source/display support and DSC.
Mini FAQ
Is 1ft long enough for most TV console setups?
It depends on your port spacing. For a nearby console or a soundbar/receiver connection with short routing, it can be convenient. If your devices are farther apart, you’ll likely need a longer cable.
Does this cable support eARC?
Yes, eARC is specifically mentioned in the product description, along with compatibility for advanced audio technologies.
Will I get 4K@120Hz and 8K@60Hz with this cable?
The listing says it supports those refresh rates under HDMI 2.1a. Real results depend on whether your source and display also support the same modes.
Does it work with HDCP 2.2 and 2.3?
HDCP 2.2 and HDCP 2.3 are listed, so it’s positioned for devices that require those protections.
What’s the warranty or assurance?
The listing mentions an 18-month breakage assurance and notes customer service support for questions or quality concerns.
