Polk Audio Signa S4 Ultra-Slim EARC SoundBar

Best EARC Soundbar Reviews and Guide


EARC (Enhanced Audio Return Channel) is a technology that allows for the transfer of high-resolution audio from a TV to a soundbar or other audio system without the need for an additional audio cable. This is achieved by using the HDMI cable that is already connected to the TV to transmit the audio signal in addition to the video signal. The best EARC soundbar is a soundbar that is equipped with this technology, allowing for a more convenient and streamlined setup process for users.

We’ve seen a lot of advancements in TVs in recent years, thanks to the introduction of Smart TVs and the numerous additional perks that came with them. Nowadays, you may access on-demand entertainment on a smart TV rather than relying on a cable provider as in the past.

Even while this new generation of Smart TVs appears to have it all, one thing appears to be missing from even the most costly options: outstanding sound quality. Because most TV makers place a premium on display and image quality, TV speakers fall behind in terms of performance. As a result, many consumers opt for a good soundbar to match their televisions.

Soundbars have a few advantages over standard home theater speaker setups: they take up less room, are easier to set up, and are frequently less expensive. There’s a model out there for everyone, whether you want a Dolby Atmos soundbar or something to plug your old MP3 player into. However, not all soundbars are made equal, and some offer a more enjoyable listening experience than others.

If you spend a lot of time at home watching TV or listening to music, you’ll want something that sounds excellent and is compatible with your existing devices, whether you want to connect it to your smart TV or prefer streaming directly from your smartphone. The best television soundbars replicate dialogue from your favorite shows with clarity and detail.

Power Output Capacity:

The main reason for using a soundbar instead of your TV’s built-in speaker is the lack of power capacity on the default speakers.
So, obviously, you’d want to get a soundbar with a high output capacity, assuring loud sound output without sacrificing sound quality.

Connectivity Options:

Because a soundbar is frequently coupled with a TV in the living room, it also becomes a part of your design, and you don’t want it to look cluttered with cables and plugs.
As a result, in order to build a clean setup, you must choose a soundbar with the appropriate connecting choices.
Right now, the finest options on the market are those that include HDMI eARC connectors for high-quality audio transmission.

Surround Sound Feature:

Aside from the soundbar’s output is loud and clear, you’d also like it to sound authentic to provide a flawless viewing experience, whether you’re watching a movie or an episode of a TV show. Surround sound characteristics on the soundbar are required for this. In this regard, there are various soundbar alternatives accessible, such as 2.1, 3.1, and even 5.1, each of which provides better results than the previous one.

Because a soundbar is simply a speaker, you must examine all of the elements that you would evaluate when purchasing a regular set of speakers. Aside from that, there are some more factors that affect the compatibility and installation of a soundbar that should not be overlooked while looking for the best options in your price range.

You’ve come to the right place if you’re not sure how to buy a soundbar. Following our recommendations for the best eARC soundbar, we will provide a “Buying Guide” for the best eARC soundbar to assist you in finding the correct one within your budget.

LG S75Q 3.1.2ch EARC Soundbar

We are all familiar with LG because it is one of the world’s leading companies in electrical items.

Along with a wonderful selection of TVs, LG also has a great selection of soundbars that are ideal for such TVs.

The LG S75Q 3.1.2 Channel Soundbar is our second choice from this list, and it is also one of the more affordable options we have for you today.

Nonetheless, LG has managed to add sound enhancement elements such as Dolby Atmos and DTS:X surround sound technology on the soundbar.

The LG S75Q 3.1.2 Channel Soundbar has a power capability of up to 400 Watts, which outperforms many other options in this price range.

If you already have an LG TV, this will be a fantastic match because all LG soundbars are intended to work with a wide range of LG TVs out of the box.

LG S75Q 3.1.2 Channel Soundbar includes an external front-firing subwoofer with the 3.1.2 audio channel arrangement, so you won’t have to compromise on the audio system’s bass response.

It also has Meridian Audio Technology, which produces high-resolution sound without the need for adjusting.

The LG S75Q 3.1.2 Channel Soundbar has both HDMI eARC and Bluetooth compatibility for a seamless connection.


  • It comes with an external subwoofer
  • Best option for LG TVs
  • Power output is pretty good


  • It does not have external tweeters or rear drivers

Polk Audio Signa S4 Ultra-Slim EARC SoundBar

Polk Audio is yet another well-known name in the audio industry, having produced numerous renowned sound systems and speakers.

Polk Audio is also offering the most popular and trustworthy alternative for an HDMI eARC soundbar on our list.

The Polk Audio Signa S4 is also one of the slimmest and most affordable options on our list of the top HDMI eARC soundbars.

Unlike most other options, however, this soundbar includes a 7-driver array as well as a full-range center channel driver to provide a complete 3D sound experience.

Along with the soundbar, it comes with a 5.25-inch-wide external subwoofer for improved bass output.

The Polk Audio Signa S4’s audio channel configuration comprises twin 1-inch L/R tweeters, dual Racetrack Mid drivers, and one 1-inch center driver.

All of this is crammed within the speaker’s 2 inch height, which is rather impressive.

You can use the optical port, analogue 3.5 mm port, USB-A port, HDMI port, or Bluetooth for wireless audio input.

You can also change the voice and bass levels coming from the device to tailor the setup’s performance.


  • One of the most trusted options on the market
  • Compatible with 4K as well as 8K TVs
  • External subwoofer for best bass response


  • Power capacity is quite low for the price

Denon DHT-S517 EARC SoundBar for TV

The Denon DHT-S517 Soundbar is our last recommendation for the best HDMI eARC soundbar.

This is also a low-cost choice that, thanks to its features, manages to give a premium-grade sound performance.

It includes twin 1-inch tweeters, dual 4.7-inch mid-rangers, one 1-inch center driver, and dual up-firing speakers with a total output capacity of 180 Watts.

As a result, this unit has little trouble producing authentic surround sound.

You may also use the Denon DHT-S517 Soundbar as a wireless speaker for wireless audio streaming by pairing it straight with your smartphone or laptop.

This is also a tiny unit, at only 3 inches tall.
However, even in that small package, you receive Dolby Atmos sound augmentation for 3D surround sound.

Furthermore, it includes Denon’s distinctive Dialogue Enhancer feature, which you should use while viewing a movie.


  • Great features for the price
  • It has 3 preset sound modes
  • External subwoofer to ensure the right bass output


  • Not an ideal choice for rooms above 1000 sq. ft. in area

Sony ST5000 7.1.2ch 800W Dolby Atmos Soundbar

The Sony ST5000 7.1.2ch soundbar and sub (available on Amazon) is the next step up from the Z9F.

The most noticeable distinction is the number of channels. This unit, like the Sonos Arc, features specialized upward-firing speakers capable of supporting Dolby Atmos, rather than the Z9F’s “vertical sound engine,” which tries to do so virtually.

It also includes a stand-alone bass, but it’s a little beefier than the Z9F equivalent.

Then there are the additional drivers meant to provide side and rear sound effects.

Coming from Sony, there’s little doubt this will be worth the money, and speaking of money, it’s not much more expensive than the other options we’ve examined thus far. Approximately 40-50% more.

Having said that, we are definitely moving up the pricing ladder with this model.

So, what are you getting for your extra money?
Connecting to Spotify and streaming music in almost any other method will be a breeze.

There’s Bluetooth if you want it, and there’s even Chromecast audio built in…a great touch that allows you to stream all types of material from your device quickly and simply; just look for the Chromecast sign.

This isn’t as fluid or as seamless as using the Sonos App or something similar, but it’s a little more elegant because it doesn’t require an app.


  • Chromecast built-in is a nice touch, arguably simpler to use than the Sonos app or some other dedicated app-controlled streaming solution
  • The power increase on this unit from the Z9F is massive. 400 watts up to 800 watts. You won’t struggle to fill a room with this sound, and if that means you don’t have to buy extra satellite speakers then it’s well worth it


  • No Airplay support, which we’d like to see at this price point
  • No output jack for additional speakers if you did want to add proper rear speakers and no indication that you could add them wirelessly after the fact.
