4K 120Hz HDMI 2.1 eARC Audio Extractor Switch (2x2) with Optical SPDIF, ARC/eARC and IR Remote
Product description
If you’re trying to get both the video you bought your console/TV for and the surround audio your soundbar or amp actually needs, this kind of HDMI 2.1 eARC audio extractor switch is meant to simplify the juggling. On paper, it’s built to let you route video from two HDMI sources into one display, while also extracting return audio (eARC/ARC) and sending it out to an external speaker path like a soundbar, AV receiver or—via optical—an SPDIF-capable setup.
The headline feature is HDMI 2.1 switching with support for 4K at 120Hz and VRR/ALLM, plus eARC and ARC audio handling. It also mentions HDCP2.3 and EDID management, which is the sort of “in the real world” detail that often decides whether setups behave nicely or keep handshaking.
Key takeaways
This is an HDMI 2.1 switcher with eARC audio extraction designed for living-room setups where you have multiple HDMI devices but want audio to consistently land on the “right” system. The included IR remote and the DIP-switch options are aimed at quick, repeatable switching.
It’s a strong fit if you want one HDMI display fed from two sources (2-in/2-out style) and you need audio extraction/out options that cover ARC/eARC and optical SPDIF (as well as HDMI ARC/eARC audio out, according to the description). Where it may fall short is if you’re expecting a fully hands-off, app-driven solution—this one leans on manual switching (IR remote and DIP switches) rather than deep automation.
Where it shines for everyday use
A common use case is a PS5 and an Xbox on the same TV, with sound going to a soundbar or amp. In practice, you’d connect both consoles to the HDMI inputs, connect the HDMI display output to your TV/projector, and then set the audio routing using the DIP switches.
Once set up, switching should be quick—helped by “seamless transitions” language in the description. If you care about gaming responsiveness, the support for 4K@120Hz and VRR/ALLM is the big reason this exists, rather than a basic switch that just mirrors whatever it’s given.
What the tech details suggest (and what to watch)
The product description is fairly broad, but the core points are clear: it supports HDMI 2.1 switch operation and multiple video formats, with stated support up to 8K@60Hz and 4K@120Hz, plus VRR and ALLM. It also calls out HDR10, “D-olby vision” support (as written), and HDCP2.3.
For audio, it lists ARC, eARC and optical audio out (SPDIF), and mentions support for formats such as Dolby Atmos and DTS:X, plus Dolby TrueHD and DTS-HD Master Audio, and PCM 7.1.
Two things to keep in mind. First, cable length is mentioned for HDMI 2.1 connections (“less than 3m”), which may matter depending on your room layout. Second, the wording is a bit inconsistent in places (for example, the description references EDID management and multiple ARC/eARC scenarios), so you’ll want to double-check that your exact TV/audio device combination matches the routing approach you plan to use.
Pros and cons to consider before buying
Pros - Built for HDMI 2.1 switching with 4K@120Hz and VRR/ALLM support for gaming-orientated setups. - eARC/ARC audio extraction concept is handy when you don’t want audio connected differently each time. - Includes optical SPDIF output (useful if your audio device supports optical) as well as ARC/eARC audio out. - IR remote plus DIP-switch control gives you a few ways to manage input/audio routing. - Mentions EDID management, which is often relevant for handshake stability.
Cons - The description leans on multiple switch modes and audio routing scenarios, so setup can be a little “choose-your-path” rather than a single plug-and-play moment. - Some compatibility claims are described as broad (“partly HDMI device” / many device brands), but that doesn’t guarantee perfect behaviour with every TV/soundbar combo. - It’s not positioned as a premium, fully automatic audio processor—expect to use the controls rather than rely on clever detection.
What to check for your setup (quick decision guide)
It’s a good fit if you have two HDMI sources you want to use with one display, and you want extracted audio to go to a speaker path that supports ARC/eARC and/or optical SPDIF. It also makes sense if gaming matters and you want the switch to handle 4K@120Hz and features like VRR/ALLM.
You may want to skip it if you only need basic HDMI switching, you don’t care about 4K@120Hz/VRR/ALLM, or your system is already routing audio cleanly with your current hardware—adding another box can sometimes add handshake quirks.
And do double-check the intended audio path: the description references DIP-switch option settings for choosing whether the audio source is HDMI IN versus eARC/ARC TV, and for selecting the soundbar eARC/ARC or AV receiver input. If you’re not sure which mode fits your TV and audio device, that’s the part to research before committing.
¿Merece la pena?
For the right buyer, it can be worth considering because it targets a specific pain point: keeping video switching and surround audio routing from stepping on each other. The combination of HDMI 2.1 switching, 4K@120Hz/VRR/ALLM support, and eARC/ARC with optical SPDIF output is the kind of feature set that usually costs more in separate boxes—so as a single “router/extractor” it has a sensible rationale.
That said, it’s not automatically a slam dunk. If your main concern is simple switching and your audio already works perfectly, a simpler switch or relying on your TV’s existing audio routing might be less hassle. It might also stay more in the “practical solution” category than the “set-and-forget perfection” category, depending on how fussy your TV and soundbar are about EDID/handshake.

Mini FAQ
Does it extract audio from HDMI devices like a PS5 or Xbox?
The description says it can extract audio from HDMI input sources such as PS4/PS5 and Xbox, sending audio out to a speaker/amplifier path.
Can it route audio to a soundbar and also provide optical output?
It references eARC/ARC audio out and an optical SPDIF (SPDIF optical audio out) output, so it appears designed to cover multiple audio connection types.
Is it suitable for 4K 120Hz gaming?
It explicitly supports 4K@120Hz and mentions VRR and ALLM, which are typical gaming requirements.
Will every device work exactly as listed?
The description uses broad phrasing for compatibility (“partly HDMI device” and many examples). It’s sensible to check your exact TV and audio device’s ARC/eARC and optical capabilities and the routing mode you plan to use.
Is setup complicated?
There are DIP-switch options and IR remote control, so expect some configuration to match your TV and audio hardware. If you want zero-touch, that may not be the best fit.
