Almost every soundbar sold now supports HDMI ARC, which makes it a poor filter on its own. Searching for it usually means someone wants the arrangement where one cable carries audio and the TV remote handles volume.
What separates bars is not whether they have ARC but what sits behind it: standard or enhanced, output or passthrough, and how reliably the control layer works. Mine runs on a port labeled ARC, and the TV remote controls the volume, which is the whole appeal. Our note on whether any HDMI port works for ARC covers finding it.
What Actually Differs
| Feature | Matters because |
|---|---|
| ARC vs eARC | Bandwidth for uncompressed formats |
| HDMI out only | Simplest wiring, one cable to the TV |
| HDMI inputs as well | Sources connect to the bar instead |
| CEC implementation | Whether the TV remote works reliably |
| Auto power and input | Bar follows the TV without intervention |
| Optical as backup | Fallback if ARC proves troublesome |
How We Picked
Selections are grouped by connection arrangement rather than by sound signature, since the wiring is what people are choosing between when ARC is the search term.
Descriptions come from documented specifications rather than hands-on testing of every option.
1. A Single HDMI Out Bar, Best Overall
Why It Stands Out
One HDMI port on the bar, one cable to the television’s ARC port, and nothing else in the video chain. It is the simplest working arrangement and the least likely to develop handshake problems.
Everything continues to connect to the television, so the bar never has to be powered on for a picture.
Worth Knowing
The television has to pass audio formats through, and some sets downgrade what they send back.
It uses one of the TV’s HDMI ports permanently. Our note on whether ARC needs a special cable covers the connection.
This suits most households. Skip it if the TV has too few ports already.
2. A Bar With HDMI Inputs, Best for Multiple Sources
Why It Stands Out
Sources plug into the soundbar and video passes through to the television, which gives the bar audio directly rather than whatever the TV chooses to send back.
It also returns HDMI ports to the television, which matters on sets with only three.
Worth Knowing
Another device in the video path, which occasionally causes handshake trouble with consoles.
The bar has to be powered for the picture to work. Our roundup of TV stands and media consoles covers housing the extra boxes.
This suits several connected devices. Skip it for a TV with built-in streaming and nothing else.
3. A Compact All-in-One, Best for Simplicity
Why It Stands Out
No separate subwoofer, no satellites, one power lead and one HDMI cable. For a normal room at normal volume that is frequently all the system needed.
Fewer components means fewer things to fail and nothing to position.
Worth Knowing
Bass is limited by enclosure size regardless of processing.
Surround effects are simulated rather than real. Our note on whether you need a subwoofer covers that trade.
This suits ordinary rooms. Skip it for a dedicated cinema setup.
4. A Bar With a Wireless Subwoofer, Best for Bass
Why It Stands Out
A separate sub handles low frequencies a slim enclosure cannot, and wireless pairing means only a power lead runs to it.
Placement flexibility matters here, since bass response changes considerably with position.
Worth Knowing
Another mains outlet and another box on the floor.
Wireless subs occasionally drop their pairing and need re-syncing. Our roundup of soundbars for dialogue clarity covers the speech side.
This suits films and larger rooms. Skip it in an apartment with neighbors below.
5. A Bar With App Control, Best for Settings
Why It Stands Out
A manufacturer app covers EQ, sound modes, and firmware updates without navigating menus on a small display.
It also provides a fallback if CEC control proves unreliable on a particular television.
Worth Knowing
An app takes longer to open than pressing a button, which matters for volume specifically.
App quality varies considerably between manufacturers. Our note on soundbar app versus remote control covers the comparison.
This suits anyone adjusting settings occasionally. Skip it if you want everything on a physical remote.
6. A Budget ARC Bar, Best Value
Why It Stands Out
ARC and CEC appear well down the price range now, so the single-cable arrangement with remote volume control is available cheaply.
For replacing television speakers rather than building a cinema, an inexpensive bar achieves most of the improvement.
Worth Knowing
CEC implementation is where budget bars economize, and that is the feature you notice daily.
Fewer sound modes and simpler processing. Our note on whether you need CEC for ARC covers the control layer.
This suits a first upgrade from TV speakers. Skip it if reliability of remote control matters most.
Why ARC Is a Weak Filter Now
ARC has been standard on televisions and soundbars for years, so shortlisting on it removes almost nothing.
What people usually mean is that they want one cable and one remote, which is ARC plus a working CEC implementation rather than ARC alone.
CEC is the part that varies. Two bars with identical ARC specifications can differ noticeably in whether the television remote controls them reliably.
That is difficult to establish from a specification sheet, which is why owner reports about remote control specifically are worth more than the feature list. Our note on turning off TV speakers covers a related negotiation.
What the Television Sends Back Matters
A detail that catches people out is that the soundbar receives whatever the television decides to send, not whatever the source produced.
A streaming app running on the television passes its audio to the bar over ARC, and the television chooses the format for that handoff.
Some sets downgrade surround to stereo before sending it back, particularly over standard ARC, so a bar capable of more never receives it.
That is why two households with identical soundbars can have different experiences. The bar is the same and the television in front of it is not.
Checking the television’s audio output format setting is worth doing after any soundbar setup, since a set defaulting to stereo will quietly limit everything downstream. Our note on soundbar vs bluetooth speaker covers the related settings.
What the Arrangement Is Like
The port on my television is labeled ARC rather than eARC, which is by far the common case and covers everything a compact one-piece bar is capable of reproducing anyway.
The television remote controls soundbar volume, so there is no second remote for the thing adjusted most often.
Settings live in the manufacturer’s app, which is a sensible place for them given how rarely any of them actually need changing after the initial setup.
That combination is the entire reason to want ARC in the first place, and once it is set up it continues working without any ongoing attention, which is what most people are actually shopping for when they search on the feature. Our note on connecting a soundbar with Bluetooth covers the alternative.
Room Size Changes the Answer
The connection question is the same everywhere and the hardware question is not.
A small room does not need a separate subwoofer, because boundaries reinforce bass and a compact bar produces enough on its own. Adding a sub in a small space frequently produces boominess rather than depth.
A larger room is the opposite case, where a slim enclosure runs out of low-end and the sub earns its floor space.
Apartments add a third consideration, since bass travels through structure far better than mid and high frequencies do, and a subwoofer is what neighbors hear.
Seating distance matters too. A bar producing simulated surround relies on reflections, and a listener very close to it hears mostly direct sound with little of the effect. Our roundup of soundbars for small living rooms covers small-space options.
What to Look For
Whether it is ARC or eARC
eARC only matters if the television supports it and the bar can use the formats.
Output only or passthrough
Passthrough returns TV ports at the cost of another device in the video chain.
Reported CEC reliability
The feature that decides daily experience and the one specifications describe least well.
An optical port as backup
Cheap insurance if ARC proves troublesome on a particular set.
Those four cover the decision. Everything else on a specification sheet describes sound rather than the connection, and sound is a separate question from whether the arrangement works day to day.
Common Mistakes to Avoid
Shortlisting on ARC alone
Almost everything has it. The differences are in CEC, port arrangement, and what the TV can send.
Paying for eARC on a TV that lacks it
Both ends must support it, and a compact bar rarely reproduces what the bandwidth carries.
Assuming any HDMI port works
One port on the television carries ARC, and it is labeled.
Buying a cable to fix a setup problem
Wrong port, CEC disabled, and audio output settings account for most failures.

HDMI ARC Soundbar FAQ
Do all soundbars have HDMI ARC?
Nearly all current ones do, which is why it is a weak shortlisting filter. What differs is eARC support, port arrangement, and CEC quality.
What does ARC actually give you?
One cable carrying audio from the television, and with CEC, control of soundbar volume from the television remote. That combination is the appeal.
What does your setup use?
A port labeled ARC rather than eARC, with the television remote controlling volume and settings handled through the manufacturer’s app.
Is eARC worth paying for?
Only if the television supports it and the bar can reproduce the formats. On a compact one-piece bar the difference is largely academic.
Should I get a bar with HDMI inputs?
If the television is short of ports, yes. It adds a device to the video chain and means the bar must be powered for a picture.
Why does the remote not control some bars?
CEC implementation varies. Two bars with identical ARC specifications can differ in how reliably a television remote drives them.
Do I need a special cable?
Not for standard ARC. Any working HDMI cable carries it, since compressed audio needs a fraction of the bandwidth video already uses.
What if ARC will not work at all?
Check the port label, CEC on both devices, and the audio output setting. An optical port is a useful fallback on stubborn televisions.
