OREI BK-21S 8K HDMI 2.1 Switch review is for buyers who need a compact way to share one display between two HDMI sources without giving up modern gaming features.
If your setup mixes a PS5, Xbox Series X/S, Apple TV, Roku, or a PC, this OREI HDMI switch is built around that use case.
OREI 8K HDMI Switch Review Summary
The OREI BK-21S makes sense for people who want two sources into one screen and care about more than basic 4K passthrough.
Its listed support for 8K@60Hz, 4K@120Hz, HDR10, Dolby Vision, VRR, ALLM, and QFT puts it squarely in the modern console-and-home-theater category, while the 48Gbps bandwidth claim gives it a clear spec advantage over older HDMI switches.
It is not a universal fix for every system, though.
The auto-switching behavior depends on a source being fully powered off, and the listing warns that cable length and audio settings matter.
That means the real appeal here is not convenience alone, but a feature set that matches users who already know their HDMI chain is the bottleneck.

Key Features and Specifications of OREI 8K HDMI Switch
The main selling point is simple: this is a 2 in 1 out HDMI 2.1 switch intended to route two HDMI sources to one display.
OREI positions it as a high-bandwidth solution rather than a basic pass-through box, and that matters because the buyers most likely to care are gaming and AV users dealing with modern source gear.
According to the listing, the switch supports:
- 8K@60Hz
- 4K@120Hz
- 1080p@240Hz
- 48Gbps bandwidth
- HDR10+
- HDR10
- Dolby Vision
- 3D
- CEC
- HDCP 2.3, 2.2, and 1.4
For gaming, the important additions are VRR, ALLM, and QFT.
Those features are what make this product relevant to PS5 and Xbox Series X/S owners instead of only casual streaming setups.
The listing also calls out support for LPCM, Dolby TrueHD, Dolby Digital, DTS-HD Master Audio, and DTS 7.1, which gives it a broad audio profile for home theater use.
The package includes the BK-21S HDMI switcher, a USB power cable, and a user manual.
OREI also says the unit is backed by a 1-year warranty and customer support.
Two practical notes stand out from the product details.
First, the auto-switching mode only activates when the current source is completely powered off, so buyers should not expect aggressive input detection.
Second, OREI recommends HDMI cable runs up to 10 feet and suggests fiber optic HDMI cables for longer runs.
That is a useful clue that signal quality is part of the design equation here, not an afterthought.
Pros and Cons of OREI 8K HDMI Switch
Pros
- Supports the specs that matter for current consoles and TVs, including 4K@120Hz and 8K@60Hz.
- Includes gaming-oriented features like VRR, ALLM, and QFT.
- Works with a wide range of common devices, from game consoles to streaming boxes and PCs.
- Offers both auto and manual switching, which gives buyers two control modes.
- Handles a broad set of audio formats, including advanced Dolby and DTS options.
Cons
- Auto-switching is limited, since it depends on a source being fully powered off.
- The product may be sensitive to cable quality and cable length.
- It is a two-source switch, so buyers needing more inputs will outgrow it quickly.
- Audio troubleshooting may still require checking source and TV settings.
Who Should Buy OREI 8K HDMI Switch?
This is a good fit for buyers with two HDMI sources and one display who want to preserve HDMI 2.1-era features.
If your priority is switching between a PS5 and Xbox, or between a console and a streaming device, the spec sheet lines up well with that kind of daily use.
It also suits home theater users who care about Dolby Vision, HDR10+, and pass-through audio compatibility.
The listing’s support for Dolby TrueHD and DTS-HD Master Audio makes it more appealing than a generic switch for setups that combine gaming and movie playback.
You should probably skip it if you need more than two sources, if your setup uses long HDMI runs without the right cabling, or if you want a device that feels completely plug-and-forget.
The feature set is strong, but it still expects a reasonably tidy HDMI chain.
HDMI 2.1 Switching and Setup Notes for OREI 8K HDMI Switch
Auto Switching Behavior
The auto mode is useful, but it is not magic.
The listing says it only activates when the currently active source is completely powered off, so it is best treated as a convenience feature rather than a full replacement for manual control.
Manual Switching Control
Manual switching remains the safer option for most buyers.
If you use multiple consoles, a PC, or a streaming box, manual input selection gives you more predictable behavior and avoids depending on power-state quirks.
Gaming and Signal Quality
The inclusion of VRR, ALLM, QFT, and 48Gbps bandwidth is the reason this switch deserves attention from gamers.
Those features suggest the product is intended to sit in a modern HDMI 2.1 chain rather than a legacy 4K setup.
Cable and Audio Considerations
The listing is explicit that cable length and audio settings can affect performance.
That is a fair warning, not a flaw by itself, but it does mean buyers should plan for compatible cables and check their TV, console, or AV settings if audio does not appear immediately.
Alternatives to OREI 8K HDMI Switch
If you want a more established switching or distribution option, consider searching Amazon for GANA HDMI switch, UGREEN HDMI switch, or Cable Matters HDMI switch.
For buyers who need more inputs or a different routing pattern, those brands are common places to compare.
If your priority is full HDMI 2.1 compatibility and you are comparing form factors, it is also worth looking at HDMI 2.1 switch 2 in 1 out search results directly.
That makes it easier to judge whether another model offers a better fit for your cable lengths, audio needs, or console mix.
Is OREI 8K HDMI Switch Worth It?
Yes, if you specifically need a two-source HDMI 2.1 switch for a console or home theater setup. The OREI BK-21S stands out because it is not just a basic input selector; it is aimed at buyers who want 8K/4K120 support, gaming features, and broad audio compatibility in one compact unit.
The caveat is that this product is best for users who can live within its limits.
If you need more than two inputs, want stronger automation, or have a messy cabling situation, the real-world benefit drops.
But for a focused two-device setup, this OREI HDMI switch is a sensible buy and a better match than a generic legacy switch.
