Grabbing a soundbar under $300 is a great way to immerse yourself in the sweeping scores of your favorite movies and the punchy dialogue of your comfort-watch sitcoms. Bypassing any built-in speakers your television might have, soundbars can enhance and elevate your viewing experience by enhancing the stereo field or even expanding it substantially. While there are several high-end (read expensive) models out there, you don’t need to spend a fortune to improve your home theater’s audio. Affordable soundbars can still deliver a high-quality listening experience with 5.1 channel systems, multiple connectivity options, and wireless playback capabilities. Beyond any special features, the best soundbars under $300 will be compact and easy to install, providing additional amplification and clarity to any soundtrack, score, or scene. 

How we selected the best soundbars under $300 

The PopSci staff has spent a lot of time researching and testing budget-friendly audio products; everyone deserves access to standout sound, so we pride ourselves on knowing what to look for to ensure all personal audio we recommend will suit listeners of various types. We looked for tempting specs and features like you’d find in luxury models but focused most on connectivity options, multi-channel systems, audio codecs, and user impressions, as well as some first-hand experience. We made sure to only recommend products from reputable brands like Vizio and Roku, which have proven they are dedicated to developing and incorporating affordable audio technology. 

Things to consider before buying one of the best soundbars under $300 

As televisions became slimmer and flat screens took over our homes, the need for additional amplification grew. Without extra room inside the TV, it became harder to incorporate suitably sized speakers, resulting in the degradation of audio quality. Enter the soundbar, which is practically guaranteed to enhance the viewing experience because they have one job: to make your content sound better. Whether you’re just looking for a bit of a bass boost or a revelatory home theatre experience, you’ll want to consider a few key features before purchasing. 

Size 

One of the most common questions asked by folks setting out to find the right soundbar for their television is, “What size should I get?” While there isn’t a one-size-fits-all answer, rest assured that soundbars are designed to be a compact, aesthetically pleasing way to improve audio, meaning you don’t need to worry about some monstrously sized speaker taking up half the living room. The common rule is don’t pick a model that is longer than your television. You want your soundbar to sit sleekly underneath the screen to maintain proper directionality and discrete connectivity. A unit that pokes out beyond the corners of your tv or hangs over the edge of your console is at best an eyesore and at worst a hazard. Try to stick to the screen size as a guiding ruler even if you have a smaller television. Soundbar size doesn’t necessarily indicate sound quality, so larger isn’t inherently better. And, with the right model, you can expand your unit to include a subwoofer, or additional speaker fills if you feel like you need more from your slim soundbar. 

Connectivity 

Most soundbars currently on the market have multiple options for connectivity—the most popular being HDMI cables. Before buying a new soundbar, it’s important to understand your television’s connectivity capabilities, so you can ensure easy setup upon arrival. 

HDMI, or High Definition Multimedia Interface, ports are a readily available way to transmit audio and visual information between a television and an external unit, like an A/V receiver or soundbar. When HDMI transmission first hit the scene, you needed one HDMI port and cable to send video and another to support audio so any pre-2009 TV will likely need a soundbar with an optical digital audio port too. 

Post-2009, HDMI-ARC connections were made available; ARC stands for Audio Return Channel and enables high audio bandwidth, as well as compatibility with remote controls via Consumer Electronics Control (CEC). Essentially, HDMI-ARC eliminated the need for a secondary cable, creating a more efficient connection. HDMI-ARC transmission is what most affordable soundbars rely on and is suitable for many TVs. Note that HDMI-ARC can support Dolby Atmos, but an eARC connection is strongly preferred and you will need that eARC support for Atmos audio encoded with uncompressed Dolby TrueHD audio. You will also need a  cable that delivers HDMI with Ethernet, High-Speed HDMI with Ethernet, or Ultra High-Speed HDMI. 

Many soundbars will not only have an HDMI-ARC or eARC port, but also an HDMI output port as well. This allows you to connnect gaming consoles and Blu-ray players to your soundbar and pass the signal through to the TV. Some models will also list Full HDMI in their list of available ports; this slot allows you to connect an additional sound source and can enable higher quality sound but can make it more difficult to play audio from the apps on your TV. 

Many soundbars on the market will also offer Bluetooth or Wi-Fi connectivity so you can link to other devices, like your smartphone or laptop, and stream podcasts, audiobooks, or music. Some even offer AirPlay 2, built-in Chromecast, or Alexa for enhanced connectivity and voice control. 

Audio channels 

At its most basic, a soundbar will offer stereo sound, meaning an independent left and right channel, also called a 2.0 channel system. Soundbar systems can generally incorporate between 1.0 and 7.2 channels. For models under $300, you’ll typically be capped at 5.1 channels and most will be packaged with 2.1 channels. These 2.1 channel systems add a separate subwoofer to take care of low frequencies. Moving up to 3.1 systems will incorporate a left, right, and center channel alongside the additional sub. And 5.1 systems will utilize one main soundbar, containing the left, right, and center channels, one subwoofer, and two additional speakers that act as surrounds, rears, or front fills for an even more immersive experience. As you can imagine, 5.1 systems take up more space and require more cabling, but for a 3D auditory experience, five channels are certainly better than two.

The deal with Dolby Digital, Dolby Atmos, and DTS:X

Dolby Digital is an audio codec that produces high-quality sound across a 5.1 channel scheme. It helps create immersive surround sound and has been used in film and television since 1992. Many soundbars will list Dolby Digital compatibility in their specs even if they are a 2.1 channel system; this simply means they can process the audio and often end up mixing down the signal, formatting it to fit the soundbar’s channel configuration. 

Dolby Atmos is a surround sound technology designed to create a realistic listening experience that puts you inside whatever movie you’re watching or video game you’re playing. To do this, Atmos utilizes overhead or upward-firing speakers and object-based audio, which essentially forgoes channel assignments and creates a 3-D plane that sound can move through, mimicking the object’s spatial organization on screen. For example, a plane may sound like it’s flying directly above you, a shootout will have bullets whizzing past your head, etc. You don’t need to build out a 12-speaker sound system complete with overhead units to take advantage of Dolby Atmos; you just need a soundbar equipped with Dolby Atmos technology. Atmos-equipped soundbars can effectively process the audio and some are designed with front-firing drivers that can virtually simulate projecting sound upwards. In order to experience Dolby Atmos, the content you are watching also has to be mixed with that technology, like select films on Netflix, iTunes, or UHD Blu-ray. Dolby Atmos does come at a higher cost but if you are looking for an incredible listening experience, we believe it’s worth the price. 

DTS:X, a multidimensional audio codec, can be considered the primary Dolby Atmos competitor. DTS:X doesn’t require any particular speaker set up, adapting to your system and supporting up to 11.2 channels. Unlike Dolby Atmos, DTS:X lets listeners customize their experience, with the option to manually adjust sound elements, like turning up the volume on just dialogue, lifting it above background music or effects. DTS: X-enabled content is predominantly found on Blu-ray disks, IMAXEnchanced content, or Xbox games. 

While DTS:X is completely immersive, DTS Virtual:X attempts to mimic multi-speaker surround sound using digital signal processing to simulate directionality and create a larger more detailed soundstage impacting music, dialogue, and SFX alike. 

Finding an inexpensive soundbar that supports well-developed surround sound technologies like Dolby Atmos or DTS:X can be difficult. So, if you are looking for a mind-blowing, 3D experience, consider saving a little bit more so you can invest in the necessary technology. 

4K compatibility 

It’s true that the 4K refers to screen resolution, not audio quality, but if you have a 4K television, you’ll want a soundbar with 4K compatibility or “pass-through.” This essentially means a soundbar with an HDMI input and output so you can create a streamlined, simple connection. This pass-through allows you to direct content from another media device through the soundbar and into the tv, maintaining lossless audio synchronization.

Why it made the cut: If investing in additional speakers (and wires for that matter) isn’t for you, but you want a little more than just a left and right channel, the Samsung 3.1 HW-A650 should do the trick. 

Specs

Connectivity options include HDMI Arc, HDMI output, Full HDMI input, USB, and optical audio, plus Bluetooth—however, there is no Wi-Fi playback option. The remote is simple and straightforward, controlling the soundbar and not the television itself. While the HW-A650 does not include a treasure trove of bells and whistles, it delivers excellent sound quality, giving you customizable control over audio.

Best budget: Roku Streambar Pro

Why it made the cut: The Streambar Pro is an inexpensive way to get solid sound quality with multiple options for control and connectivity. 

Specs

  • Dimensions: ‎32.2 x 3.9 x 2.8 inches 
  • Connectivity: HDMI ARC, Bluetooth, optical 
  • Audio Channels: 2.0

Pros 

  • Price 
  • Private Listening option 
  • Voice Contol 
  • AirPlay and HomeKit compatible 

Cons 

  • Bass could be better 

You don’t need to have a Roku TV to take advantage of all this powerful, compact soundbar has to offer. The Streambar Pro features four 2.5-inch full-range drivers that support powerful 2-channel stereo sound, gracefully enhancing movies and TV shows, but it might not pack a huge punch for music listening. Speech Clarity helps with clear dialogue, though. Luckily, Roku makes it easy to expand with the option to incorporate additional wireless speakers or a wireless subwoofer down the road if you want to round out your listening experience. The included remote contains typical features like control over volume and playback and provides unique additions like programmable command buttons and a headphone jack for private listening wirelessly, allowing you to experience big-screen visuals without waking up your roommates. A Night Mode also helps not disturb the neighbors. The Wi-Fi-enabled Streambar Pro works with Alexa, Siri, and Google Assistant and is also compatible with AirPlay, so you can share photos, videos, and music from your Apple device. While this soundbar supports Dolby Audio, it will mix down to virtual without any speaker expansions. This soundbar also acts as a 4K HDR Roku media streamer, providing access to apps including Hulu, Netflix, Spotify, YouTube, Amazon Prime, as well as Roku Channel exclusives, assuming you have a compatible UHD TV with an HDMI input that supports HDCP 2.2. 

FAQs

Q: Does a soundbar replace TV speakers?

Yes, a soundbar is designed to replace your television’s built-in speakers. You cannot use both the TV speakers and soundbar to create an enhanced system, it’s likely you will just create an annoying echo. Soundbars are specifically structured to be better than your built-in speakers, which are often crammed into a skinny TV and too small to produce the kind of sound that should accompany film and television. You are sure to notice a difference the next time you watch an episode of Euphoria and feel Labrinth’s score soar around you or finally dig into Dune and fear the sandworms might come through the screen and attack you thanks to immersive, elevated sound. 

Q: Is a soundbar better than a surround sound system?

While a soundbar is a great way to improve your home theater’s sound, a full surround sound system might be the best way to create an even more 3D experience. Larger drivers across at least four speakers plus a subwoofer can often provide more detail than the small units found in soundbars. However, while the audio quality may be better, surround systems are typically more expensive, harder to install, and require additional receivers. For a budget-friendly, easier-to-use option, we recommend looking at a package that includes a soundbar with a couple of supplementary speakers and a sub, like the Vizio M51ax-J6.

Q: What is the difference between 2.1 and 3.1 soundbar?

The difference between a 2.1 and 3.1 soundbar is the additional center channel in the 3.1 system. A 2.1 channel system includes a left and right channel built into the soundbar with an additional subwoofer. A 3.1-channel system will incorporate a left, right, and center channel, as well as the sub. The biggest perceivable difference will be in the clarity of dialogue, which is typically mapped to the center channel.

Final thoughts on picking the best soundbars under $300 

If you’ve decided to upgrade your TV’s audio, but you don’t want to break the bank, consider which features are non-negotiable so you can find something that fits your needs and your budget. Do you want to invest in true 5.1 surround sound? Are you satisfied with stereo but need a universal remote? Do you need multiple connectivity options? Or would you rather be able to have complete control over EQ? Once you can answer these questions, you can narrow your search and select one of the best soundbars under $300.
