1. VPFET HDMI eARC Extractor – Best Focused Digital Audio Solution
VPFET HDMI eARC Extractor
Toslink and coaxial outputs
24-bit/192 kHz support
ARC and eARC input
Status indicator included
The VPFET HDMI eARC Audio Extractor is a purpose-built converter for televisions with an ARC or eARC port but without a convenient optical or coaxial connection for the user's sound system. Its 4.1 rating reflects generally favorable feedback, while the feature set centers on dependable digital audio extraction rather than broad HDMI routing. It is especially appropriate for connecting a soundbar, amplifier, DAC, or headphone amplifier that accepts digital audio.
Pros
- Dual digital outputs
- High sampling-rate support
- Backwards-compatible ARC mode
- Useful cables included
- Compact plug-and-play design
Cons
- No CEC volume control
- Requires compatible TV port
We may earn a commission when you buy through this link, at no additional cost to you.
Its standout quality is the inclusion of both Toslink and coaxial outputs, allowing one extractor to serve equipment with either digital interface. The converter supports sampling rates as high as 24-bit/192 kHz, and its eARC interface provides greater bandwidth than ordinary ARC for compatible multichannel signals. A dedicated operating-status indicator makes setup easier, while the included Type-C power cable, 19+1 HDMI cable, optical cable, and manual create a largely ready-to-install package.
The main limitation is that optical and coaxial volume control through the television is not available. Some TVs also do not support ARC volume control at all, meaning users may need to adjust volume on the receiving amplifier or speakers. It only works with a television ARC or eARC port; plugging it into an arbitrary HDMI input will not turn that source into an eARC signal. It also does not pass video through.
This is a sensible choice for a straightforward television-to-digital-audio setup, especially when both optical and coaxial options are useful. Choose it when the goal is clean extraction into existing digital equipment, not HDMI switching, 8K video passthrough, or television-remote volume control.
Digital Output Flexibility
Providing both optical and coaxial outputs reduces adapter shopping and makes the device useful with more soundbars, amplifiers, and DACs. The outputs can be used simultaneously according to the supplied information, giving listeners options for connecting one or both types of equipment.
Understanding the TV Requirements
ARC or eARC must be enabled on the television, and the correct cable should be connected to the labeled port. If there is no sound, check the TV's speaker and external-audio settings, confirm the adapter is powered, and adjust volume on the downstream device.

Cons
- No surround formats
- Requires TV PCM setting
We may earn a commission when you buy through this link, at no additional cost to you.
The device supports sampling rates up to 24-bit/192 kHz while handling PCM and PCM 2.0 audio. Audio status indicators help confirm operation, and USB power enables a straightforward setup without software or drivers. The television's ARC or eARC port serves as the source, while users select PCM in the television menu to ensure the converter receives a compatible stream.
Its crucial trade-off is a lack of surround and encoded audio support. Dolby, DTS, and other non-PCM streams are outside its documented capability, which means it is not suitable for someone hoping to preserve a 5.1-channel or object-based home-theater soundtrack. The absence of optical and coaxial outputs also makes it less versatile for modern soundbars and digital amplifiers.
This is the strongest recommendation for listeners who specifically need analog headphones or stereo speakers rather than digital surround. It is simple, purpose-specific, and backed by the strongest rating in the list, but buyers should confirm that PCM 2.0 output is acceptable for their viewing habits.
A Better Path to Headphones
A 3.5mm output avoids the need for a wireless headphone transmitter when the television is the desired sound source. Connect the extractor to the television's ARC or eARC port, select PCM, and use headphones or powered speakers with the appropriate analog input.
Format Restrictions Matter
The extractor is designed for stereo PCM rather than surround bitstreams. Before buying, review the formats used by the television apps and streaming services of interest, because those sources will need to deliver compatible PCM audio to the adapter.

PASS mode mirrors the source's native audio, with optical output accepting multichannel formats. R/L mode downmixes PCM, Dolby Digital, Dolby TrueHD, and DTS-HD into 2.0 PCM across the analog and optical outputs. SPDIF mode preserves premium multichannel formats through the optical connection. This flexibility lets a user choose between a faithful digital feed and a compatible stereo mix without changing hardware.
Video support extends to 8K at 60 Hz or 4K at 120 Hz with several color formats, although the source, display, and cable must all support the target resolution. In eARC mode, the television's ARC or eARC port connects to the HDMI output. A Type-C 5V supply is mandatory, and a television must not be connected directly to the HDMI input as a signal source.
This model fits users who want one box to cover television return audio, source extraction, legacy analog equipment, and digital surround equipment. It is less attractive for a simple one-cable installation, but its operating-mode flexibility makes it a strong choice for complex entertainment racks and mixed audio systems.
Choose the Right Audio Mode
PASS and SPDIF modes are best for digital receivers that can decode the incoming stream. R/L mode is more forgiving because it converts supported surround formats to 2.0 PCM for analog outputs, helping users avoid buzz or hum from incompatible signals.
Resolution Requires Matching Hardware
An extractor cannot create display capabilities that the television or monitor lacks. To attain the advertised high resolution, every link in the chain—source, extractor, cable, and display—must support the desired format and refresh rate.

We may earn a commission when you buy through this link, at no additional cost to you.
Optical output supports Dolby Digital 5.1 and DTS 5.1, while RCA and 3.5mm provide two-channel stereo. The analog outputs can be volume-controlled with the television remote when CEC and PCM or LPCM are enabled. By contrast, the optical output requires volume adjustment on the amplifier or soundbar, so remote-control behavior depends on the connection type.
Setup involves connecting the extractor to the television's ARC or eARC port, enabling CEC, and selecting HDMI ARC or eARC as the television's audio output. The supplied information lists 3.3-foot optical, HDMI, and power cables, supporting a relatively quick installation. Users should still verify that their chosen output and source formats are mutually compatible.
This is a balanced recommendation for users who want surround sound through optical and personal or stereo listening through analog outputs at the same time. Its main inconvenience is inconsistent volume-control behavior across output types, but that is manageable once each connected device is configured correctly.
One Source, Several Listening Options
The simultaneous outputs allow a sound system and headphones or stereo speakers to be connected from the same extractor. This is useful for daytime family viewing and private nighttime listening without repeatedly reconnecting the television.
Volume Control by Output Type
RCA and 3.5mm users can potentially use the TV remote after enabling the required CEC and PCM settings. Optical users should expect to control volume on the receiving amplifier, because the digital path does not provide the same remote-control behavior.

Documented format support includes PCM, AC3, DTS, DD+, DTS-HD Master Audio, and Dolby True HD. Sampling rates of 32, 44.1, 48, 96, and 192 kHz are supported, with 24-bit SPDIF input bitstreams for the left and right channels. RCA and 3.5mm outputs may respond to the television remote, while the HDMI and optical paths do not support CEC.
One significant limitation is that simultaneous multichannel output is not supported. Users must select an output mode appropriate to the destination equipment rather than expecting every port to carry the same advanced surround signal. The distinction between HDMI and analog volume-control behavior also requires planning before installation.
This extractor is a good fit for a mixed home-theater setup, conference room, or classroom where different devices need different connections over time. It is particularly attractive when optical input and broad format support matter more than sending multiple multichannel feeds at once.
Connections for Different Equipment
HDMI and optical outputs suit modern soundbars and AV receivers, while RCA and 3.5mm address traditional amplifiers, computer speakers, and headphones. The wide selection makes it easier to reuse the extractor when equipment changes.
Avoiding Multichannel Conflicts
Because simultaneous multichannel output is unavailable, select the port that matches the primary listening system. Trying to combine incompatible formats across several destinations may produce noise, silence, or an unintended stereo downmix.

The included package contains the extractor, optical cable, eARC/ARC cable, and USB power cable. A status LED confirms power and signal, and the unit needs no drivers or software. The supplied information highlights its suitability for optical-only soundbars, wireless headphone bases, and home-theater systems that need a digital connection from a newer television.
CEC is not supported, so the television remote cannot control volume through the optical connection. Volume must instead be changed on the soundbar, amplifier, or headphone base. Users also need a television with a clearly labeled ARC or eARC port; a standard HDMI input will not function as the required return-audio source.
This is a compelling recommendation for a clean two-cable installation when the receiving device has an optical input and nothing else is needed. It avoids unused jacks and complicated mode settings, making it easier to understand and maintain than a multi-output converter.
Less Cable Clutter
With a dedicated optical output, the connection path is easy to understand: television return audio enters through the eARC or ARC cable and leaves through the optical cable. This simplicity can reduce installation errors in an unfamiliar entertainment setup.
Separate Volume Control
Because CEC volume control is unavailable, the downstream device becomes the volume authority. This is often preferable to volume synchronization problems, but it also means the television remote will not cover audio levels.

The extractor can pull full audio from an HDMI source while passing 8K or HDR video to a compatible display. A dedicated HDMI audio-only output can connect to an AV receiver and support Dolby Atmos, Dolby True HD, Dolby Digital, DTS Digital, DTS-HD Master, 7.1- and 5.1-channel audio, and multichannel PCM. HDMI 2.1 features include VRR, ALLM, QMS, QFT, and SBTM.
Compatibility boundaries are significant. The product is not designed to extract eARC to a soundbar, so a receiver with HDMI input is the intended destination. It also requires compatible source devices, an ARC or eARC television for the return-audio path, and an AV receiver capable of receiving the appropriate HDMI audio signal.
This is the pick for an enthusiast who needs modern HDMI routing and broad surround support rather than a simple headphone adapter. The lower rating and specialized requirements should be weighed carefully, but the hardware specification set is well suited to high-end source, display, and receiver combinations.
Purpose-Built AV Routing
Unlike a simple ARC converter, this unit separates video handling from the dedicated HDMI audio output. That arrangement can send a source's picture to a modern television while routing the same source's audio to a suitably capable AV receiver.
Understand the Soundbar Limitation
The supplied compatibility notice explicitly excludes eARC soundbars. Buyers seeking a television-to-soundbar eARC link should choose one of the dedicated ARC-to-optical or analog extractors instead.

We may earn a commission when you buy through this link, at no additional cost to you.
The extractor supports PCM 2.0, PCM 5.1, Dolby 5.1, and DTS 5.1. Its physical power switch and LED indicator aid setup and status checks. A standard USB power cable and manual are included, and the product includes a US plug with an international adapter.
Dolby AC3 and Dolby Digital Plus are explicitly excluded, which is an important limitation for modern streaming ecosystems. The device also has no CEC, so volume must be changed on the connected receiver. An HDMI 2.1 cable is advised for eARC support, while an ARC television requires its ARC feature to be switched on.
This converter is best for a specific legacy scenario: a receiver with optical or coaxial input that should receive conventional 5.1 surround audio from an ARC or eARC television. It is less future-proof than models with broader format support, but it remains clearly focused and comparatively easy to operate.
Keeping the Receiver Connected
Optical and coaxial outputs cover two generations of digital audio equipment. Instead of replacing an older receiver, the converter lets it remain connected to a modern television through the ARC or eARC return-audio path.
Check Streaming Format Compatibility
Dolby Digital Plus is not supported, so users should verify which format their television sends over ARC. This matters especially when a streaming service commonly supplies enhanced or object-based audio that the receiver cannot process.

Audio can be sent through optical SPDIF, left/right analog, or HDMI audio output. Optical supports standard Dolby Digital 5.1, HDMI output supports up to 7.1-channel audio, and analog output is limited to stereo. The output format therefore needs to match the capabilities and user preferences of the receiving equipment.
Video can pass through at 8K60 or 4K120 with support for HDR, HDR10+, Dolby Vision, and HLG. A DIP switch provides EDID management for source and display compatibility. CEC support can provide volume control over compatible ARC or eARC connections and aid synchronization between the television, source, amplifier, or soundbar.
This extractor is a strong premium recommendation for a modern, mixed home-theater system where HDMI flexibility, video passthrough, digital surround, analog audio, and remote-control integration are all valuable. It is less necessary for a single simple soundbar or headphone hookup, and users should verify that the intended output path supports their preferred formats.
Modern HDMI Capability
Support for 8K60, 4K120, HDR variants, and HDCP 2.3 positions this extractor for current high-performance displays and sources. The full video and audio chain must support each feature, so advertised resolution is not a guarantee in every setup.
EDID Helps Source Recognition
The DIP-switch EDID controls let installers influence how sources perceive the connected display or audio system. This can improve compatibility when a source does not automatically output the expected audio format or resolution.

Buying Guide – How to Choose the Best Earc Audio Extractor
Choosing an eARC audio extractor starts with the exact ports on the television and receiving equipment. Beyond physical connectors, buyers should evaluate channel formats, video requirements, remote-control behavior, and whether the device must also extract audio from ordinary HDMI sources.
Confirm the Television Input
Choose only after confirming that your television exposes the required return-audio port.
Match Every Output Type
Map the extractor's outputs to the inputs already present in your audio system.
Understand Channel Support
For home theater, match the extractor's decoded or bitstream formats to the amplifier.
Review HDMI Resolution Needs
Prioritize HDMI 2.1 features only when your existing equipment supports them.
Check Remote Volume Control
Treat remote volume control as a separate feature, not an automatic eARC benefit.
Consider Included Accessories
Inventory the required cables and confirm what the package actually includes.
Assess Setup and Signal Behavior
Choose a product whose operating modes align with your source and output formats.
Weigh Port-Count Simplicity
Prioritize needed connections over a larger but conflicting output set.
How to Use and Care for Your Earc Audio Extractor
Begin by identifying the television's ARC or eARC port and the input type required by the audio receiver. Connect the appropriate HDMI cable from that labeled television port to the extractor, connect a matching optical, coaxial, RCA, 3.5mm, or HDMI audio cable to the destination, and then provide the required USB or DC power. Position the unit where its status light remains visible and where cables will not be strained.
On the television, enable ARC or eARC and HDMI-CEC where applicable, select the correct external-audio output, and choose a compatible format. PCM or LPCM is commonly needed for analog outputs, while a digital receiver may require Dolby Digital, DTS, or another supported bitstream. If there is no sound, confirm power, inspect the television's speaker settings, try the correct operating mode, and adjust volume on the downstream device.
For ongoing care, keep the extractor away from moisture, direct heat, and cramped ventilation spaces. Route optical cables without sharp bends, avoid hanging heavy plugs from the unit, and clean the ports with a dry soft cloth. Periodically confirm that firmware-related television settings, source formats, and cable connections remain unchanged, especially after a streaming service or television update.
Frequently Asked Questions
What is an eARC audio extractor used for?
An eARC audio extractor separates television audio from the TV's return-audio path and sends it to another device. It is useful when a newer television has eARC or ARC but the soundbar, amplifier, DAC, or headphones require optical, coaxial, RCA, 3.5mm, or another compatible input. The exact audio formats depend on the extractor and the connected receiver.
Can I connect an extractor to any HDMI port?
Not always. Products designed exclusively for television return audio require a port labeled ARC or eARC, and some specify that other HDMI devices are unsupported. Advanced extractors may also have a separate HDMI input for sources such as game consoles or streaming boxes. Check the product's stated input requirements before connecting anything.
Does an eARC extractor support Dolby Atmos?
It depends on the model and output path. An extractor can preserve an advanced bitstream only when the television sends it, the extractor supports that format, and the receiving amplifier can decode it. Many analog outputs support only 2.0 PCM, while some optical or HDMI outputs support surround formats. Dolby Atmos requires compatible handling throughout the entire chain.
Why can I control volume with the TV for one output but not another?
Remote-control behavior varies by connection type and extractor. RCA or 3.5mm outputs may support television-remote volume when CEC and PCM or LPCM are enabled, while optical outputs often do not. Extractors without CEC provide no remote control at all, so the amplifier, soundbar, or headphone device must be used to set the volume.
Do I need an HDMI 2.1 cable?
It depends on the extractor and the signal you intend to carry. Some products advise HDMI 2.0 or 2.1 for eARC, while high-resolution models may require a cable that supports 8K or 4K120. A standard TV-to-extractor audio connection may work with a suitable 19+1 HDMI cable, but it must meet the requirements of the product.
Why does the optical output buzz or remain silent?
A buzz usually indicates that an incompatible non-PCM stream is reaching a stereo output, while silence may result from disabled ARC, incorrect TV settings, missing power, an unsuitable mode, or a source using an unsupported format. Select PCM for analog outputs, use a surround-capable mode for digital receivers, and confirm every cable and port is seated correctly.
Can an extractor replace an HDMI eARC soundbar connection?
It can help when the soundbar has an optical or coaxial input, but it is not always a direct replacement for eARC. One product in this guide explicitly cannot extract eARC to a soundbar, and other models may downmix or limit formats. Match the extractor to the soundbar's actual input rather than assuming every eARC-compatible television can work with every converter.
Should I buy an 8K extractor for a 4K television?
Usually not unless the setup also needs HDMI source extraction, high-resolution video passthrough, or advanced features such as VRR and ALLM. If the only goal is pulling television sound into a soundbar or amplifier, a focused ARC-to-optical or analog model is usually easier to use. The extra HDMI capabilities are valuable only when the entire connected chain supports them.
Final Thoughts on Choosing the Best Earc Audio Extractor
The VPFET is a focused, cost-conscious digital solution with useful optical and coaxial outputs, while the eSynic Professional analog model is the strongest fit for headphones and stereo speakers. The J-Tech Digital model takes the premium route with 8K60 and 4K120 support, several output types, CEC, and EDID management for more demanding installations.
Most buyers should prioritize the required connector, supported audio format, and television return-audio behavior over headline resolution. Optical-only users need a digital receiver with compatible surround decoding; analog users should verify PCM support and remote-control expectations; advanced users should ensure that cables, source devices, displays, and amplifiers all support the advertised HDMI features.
Prices, ratings, inventory, and package contents can change over time, so check the current listing before purchasing. Most importantly, verify that the television has the correct labeled port and that the downstream system accepts the exact output format the extractor supports.
