JSAUX 4K HDMI Cable 3M (Ultra High Speed 18Gbps, HDMI 2.0) – HDR, HDCP 2.2, ARC & Ethernet, Grey
Product description
If you want a straightforward HDMI lead that can handle modern 4K TVs, this JSAUX 4K HDMI Cable (3M) is aimed at everyday home theatre and gaming set-ups. On paper it supports HDMI 2.0 features, including 4K HDR up to 60Hz, plus HDCP 2.2 and ARC, with a full 18Gbps bandwidth.
Still, it’s worth reading past the headline numbers. HDMI cables rarely fail spectacularly, but the “right” choice depends on your device mix (TV sound system, consoles, streamers) and whether you actually need features like ARC/Ethernet.
The essentials (what it is and what it’s for)
This is a 3 metre HDMI 2.0 cable designed to carry video and audio between HDMI devices, from 4K TVs/monitors/projectors down to 1080p sources. It’s positioned as a no-fuss replacement or upgrade lead for home cinema, gaming, office setups and conference-room style use, where you want dependable signal transfer without adding converters.
A key part of the pitch is 4K HDR support: it’s specified to handle resolutions up to 3840 × 2160 at 60Hz (with 18Gbps bandwidth). It also mentions HDR-friendly colour support (48-bit Deep Color), 3D support, and audio support features such as up to 32 audio channels.
For a micro “real life” example: if you’ve got an Apple TV or Fire TV box connected to a 4K TV and you’re noticing a flaky connection when you move equipment around, a 3M cable length like this can be the practical fix—enough slack for tidy routing, without forcing the gear to sit in awkward positions.
What you’ll notice in day-to-day use
Where this cable tries to stand out is stability and interference resistance. It includes an anti-interference design, with 24K gold-plated connectors and layered shielding (described as tinplate and durable zinc alloy shielding). The claim is that this helps minimise signal loss and reduces issues like screen flickering or blackouts.
It also specifically calls out WiFi-related interference, saying the cable is designed so WiFi performance remains unaffected when connected. That doesn’t mean every setup will behave identically, but if you’ve had headaches where cables seem to coincide with network dropouts, it’s a relevant detail.
On the spec side, it supports HDCP 2.2 (useful for certain protected content paths) and includes ARC support via Audio Return(ARC). That matters if you want sound to travel “back” from your TV to an ARC-capable soundbar/AV receiver using a single HDMI link.
Key features that matter (and where they help)
The headline feature set is fairly complete for an HDMI 2.0 lead. It’s described as supporting:
- 4K HDR video up to 60Hz (3840 × 2160) with 18Gbps bandwidth
- HDCP 2.2, 3D, and 48-bit Deep Color
- ARC (Audio Return Channel) for TV-to-audio routing
- Ethernet support (not every household uses this, but it’s there by design)
- AudioReturn and Dolby TrueHD 7.1 audio are mentioned, alongside support for multiple audio channels
- Backward compatibility with 1080p devices
One small reality check: while the cable supports these formats, the actual experience depends on what your TV, console or streamer supports too. You can’t force a device to output a feature just because the cable claims support.
Spec sheet, in plain English
It’s an HDMI to HDMI cable with HDMI 2.0 support and an “Ultra High Speed” rating of 18Gbps. The important practical detail is the length: 3M (10ft), which typically suits most living room and gaming-desk arrangements where your devices aren’t stacked directly side-by-side.
It’s also described as plug-and-play with no adapters or drivers needed.
Pros
- Built for 4K HDR (up to 4K at 60Hz) with HDMI 2.0 / 18Gbps on the spec sheet
- ARC support included, helpful if you want TV sound routed through your AV setup
- HDCP 2.2 listed, which can matter for certain protected content formats
- Designed with anti-interference and shielding, aimed at reducing flicker/blackout type problems
- 3M length gives flexibility for typical home theatre and gaming layouts
Worth noting / limits before you buy
It’s not guaranteed to fix every “signal problem” you might have. If the issue is caused by a faulty HDMI port, damaged device output, or poor cable seating, even a well-shielded lead may not be the full answer.
Also, if you only ever watch in 1080p or you don’t use ARC/Ethernet, you may be paying for features you won’t practically use. In that case, it might not be the most sensible spend.
Finally, if your priority is maximum long-distance reliability, remember that cable performance is affected by installation and the rest of your setup, this product is positioned as a standard 3M home/office lead rather than a specialist for extreme runs.
¿Merece la pena?
A solid pick if you want a 3M HDMI 2.0 cable that’s ready for 4K HDR up to 60Hz, with ARC and HDCP 2.2 listed for the kind of home entertainment setups people actually run. The shielding and anti-interference angle is also a sensible detail if you’ve had flicker or dropouts that seem to correlate with how your gear is arranged.
You may want to skip it if you’re purely running basic 1080p feeds and don’t need ARC, Ethernet, or modern protection support. In that scenario, a simpler cable might do the job without paying for unused features.
Who it suits (and who should avoid it)
It makes sense if you’re building or updating a home cinema or gaming station with 4K HDR playback, and you need a cable long enough to avoid stretching or putting devices too close together.
It may not suit you if your main aim is solving a non-cable issue (like a worn HDMI port) or if you only need a short 1–2M connection for basic 1080p viewing.
Practical buying checklist (quick things to double-check)
Before ordering, it’s worth checking that your TV and source devices (like an Apple TV/Fire TV box, console or media player) actually output the format you care about. Also confirm your audio setup supports ARC if you plan to rely on TV sound returning through the HDMI connection.
If WiFi interference has been part of your problem, think about how your cable will be routed—twisting cables together, sharp bends and loose connections can still cause trouble even with shielding.
