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.
