Buy it to pull full surround audio off a TV or console and feed an older HDMI receiver, while the picture stays on the display. It will not work with an eARC soundbar, so that buyer should look elsewhere.

Overview
A gamer or home theater owner with an older HDMI receiver gets a small box that splits the signal: video continues to the TV while audio leaves through a dedicated HDMI audio only port. The unit reads the eARC or ARC return from the display, or takes audio straight from a cable box or console, and passes it to the receiver in the format it already understands. It can rest on a shelf or be screwed to a wall.
The reason to add this box is the dedicated HDMI audio only output, which lets a receiver that predates eARC still receive the full surround mix. Video and audio travel on separate paths, so the display receives the high frame rate and HDR signal while the receiver handles sound. The limitation is narrow but firm: soundbars with eARC are excluded, and the listing does not state cable lengths or package contents beyond the extractor itself.
Who it's for
Rooms where a receiver and speakers already exist and only the audio path needs modernizing, with a TV or console as the source. The box also suits wall or shelf placement near the receiver rather than inside a rack of analog gear. Buyers running an eARC soundbar should not order it, and neither should anyone expecting cables or a remote in the box.
Pros and cons
- Dedicated HDMI audio only output for receivers
- Passes Atmos, DTS HD Master and multichannel PCM
- Handles 8K and high refresh 4K video
- Supports VRR, ALLM and related HDMI 2.1 features
- Not compatible with eARC soundbars
- Cable length not listed
- No remote or mounting hardware listed
- Audio formats depend on the connected receiver
Performance notes
The extractor is placed between source, display and receiver, reading the audio stream and routing it out the audio only port while the video continues untouched to the TV. Whether surround formats arrive intact depends on what the receiver advertises over EDID, so a receiver limited to older codecs will negotiate down. eARC mode depends on the display actually outputting the return channel, and the box cannot create audio the TV does not send.

Frequently asked questions
What do I need to install the Orei BK-927?
The box itself is the only listed included component, so plan on your own HDMI cables and a place to set or mount it. It ships with a dual voltage supply using a US plug and an adapter for international outlets. The housing can rest on a shelf or be attached to a wall.
Will the BK-927 pass video features like VRR and ALLM through to my TV?
Yes. Support covers VRR, ALLM, QMS, QFT and SBTM as specified in HDMI 2.1, along with 8K at 60Hz, 4K at 120Hz and HDR. The video path stays separate from the audio path, so the display receives the picture signal directly.
Can I use this extractor with an eARC soundbar?
No. The compatibility notice states it is not compatible with eARC soundbars. It is built to send an HDMI audio only signal to an AV receiver with an HDMI input, including receivers that predate ARC.
Which audio formats can reach my receiver?
The audio only output supports Dolby Atmos, Dolby True HD, Dolby Digital, DTS Digital, DTS HD Master, Dolby and DTS 7.1 and 5.1, plus PCM 7.1, 5.1 and 2.0 stereo. What you actually hear depends on the formats your receiver accepts.
Does the BK-927 need a specific power setup?
The supply covers 120 to 240 volts and comes with a US plug plus an adapter for international use. No other power requirement is listed.
