The Bose Smart Soundbar 300 is a small 3.0 setup from 2020. It has an excited v-shaped sound profile that's suitable for a variety of audio content. While it lacks thump and rumble in its low-bass, there's a bass adjustment feature to help tweak its sound to your liking. However, there's no EQ or room correction feature, which is a little disappointing. The bar also doesn't support Atmos. On the upside, this setup can be expanded down the line as the manufacturer sells a bass module subwoofer and satellites separately.

Our Verdict

7.1 Mixed Usage

The Bose Smart Soundbar 300 is decent for mixed use. This bar has an excited v-shaped sound profile that's suitable for rock or pop music. While it lacks low-bass, which can affect the immersiveness of sound effects in movies, there's a bass adjustment feature to help tweak its sound. If you prefer vocal-centric content, it can produce clear and accurate dialogue. Unfortunately, the bar doesn't support Atmos.

Pros
  • Outstanding wireless connectivity options.
  • Bass adjustment feature available.
  • Can get loud with minimal compression artifacts.
Cons
  • No EQ or room correction.
  • Lacks low bass.
  • Doesn't support Atmos.
7.8 Dialogue/TV Shows

The Bose Smart Soundbar 300 is good for dialogue and TV shows. It produces clear and accurate dialogue, thanks to its decently balanced mid-range and dedicated center channel. There's a dialogue enhancement feature available via its companion app to further improve vocal clarity. You can also stream your favorite podcasts or audiobooks to the bar using Bluetooth, Wi-Fi, or Apple AirPlay 2.

Pros
  • Dialogue enhancement feature available.
  • Outstanding wireless connectivity options.
Cons
  • No EQ or room correction.
7.3 Music

The Bose Smart Soundbar 300 is decent for music. It has an excited v-shaped sound profile that's well-suited for pop or rock genres. However, it lacks quite a bit of low bass. While it doesn't come with an EQ, it has a bass adjustment feature so that you can tweak its sound a bit. The bar can also get loud with minimal thumping and compression artifacts. You can also stream your favorite music using Bluetooth, Wi-Fi, or Apple AirPlay 2.

Pros
  • Bass adjustment feature available.
  • Can get loud with minimal compression artifacts.
Cons
  • No EQ or room correction.
  • Lacks low bass.
6.4 Movies

The Bose Smart Soundbar 300 is acceptable for movies. It doesn't support Atmos and although it has an excited v-shaped sound profile, it lacks a thumpy low bass, which impacts the immersiveness of sound effects. There's no EQ either, which is a little disappointing. Luckily, you can adjust the bass. It can also get loud enough to fill a large or crowded room.

Pros
  • Bass adjustment feature available.
  • Can get loud with minimal compression artifacts.
Cons
  • No EQ or room correction.
  • Lacks low bass.
  • Doesn't support Atmos.

The Bose Smart Soundbar 300 is a 3.0 setup from Bose's 2020 lineup. It's a small model that can be expanded down the line. Unlike the Bose TV Speaker, which is also from the same 2020 lineup, you can connect to the bar using Apple AirPlay 2 and use the Bose Music companion app with it. It also has a Wall EQ setting that's advertised to improve the bar's sound when wall-mounted. Its main competitors are the Bose Soundbar 500, the Bose Soundbar 700, and the Sonos Beam.

While it's not as small as the Bose TV Speaker, this bar can easily fit between the legs of a 55" TV. It's not very tall either, so it shouldn't obscure your TV unless the screen sits flush to the table.

The Bose Smart Soundbar 300 has a decent stereo frequency response. While it really lacks a thumpy low-bass, it's still able to produce punch and boom. Since it has a v-shaped sound profile overall, its mid-range is well-balanced while its treble range is bright, making it especially well-suited for rock and pop music. It's still balanced enough for most audio content though. It doesn't have any EQ presets; however, it does have bass and treble adjustments.

The Bose Smart Soundbar 300's stereo soundstage is good. The soundstage is wider than the bar itself, which is impressive for its small size. However, it doesn't have the best focus, so objects sound like they're coming from diffused or more general areas rather than accurate, pinpoint locations.

The Bose Smart Soundbar 300's stereo dynamics are good. The bar can get loud, making it suitable for a large or crowded room. However, there's a little bit of thumping and compression artifacts, particularly in the bass range. It shouldn't be too noticeable to most users, though.

The Bose Smart Soundbar 300 has a great THD performance. At a normal listening volume, the THD falls within good limits. If you push this bar to its max volume, there's a small jump in THD, particularly in the high-mids, but it can be hard to hear with real-life content.

The Bose Smart Soundbar 300 has a poor surrounds performance. Since it's a 3.0 setup, it has to downmix surround content into stereo to play it, which doesn't result in the most accurate or clear representation of objects in the surround image. The result is a bass-heavy sound that isn't very immersive as objects are perceived as coming from in front of you rather than from beside or around you.

The Bose Smart Soundbar 300 has poor sound enhancement features. It doesn't have an EQ or room correction features. On the upside, you can tweak its bass, treble, and center channel levels. There's also a dialogue mode that's available via its app as well as a 'Wall EQ' which is advertised to help improve the bar's sound when wall-mounted. However, we don't currently test this feature.

Compared to other soundbars

The Bose Smart Soundbar 300 is a 3.0 setup from this manufacturer's 2020 lineup. This small soundbar can be expanded down the line with a separate bass module and satellites. Unfortunately, unlike the Bose Soundbar 500, it doesn't have any EQ presets. If you're looking for more soundbars, check out our recommendations for the best Bose soundbars, the best small soundbars, and the best soundbars for dialogue.

Sonos Beam

The Sonos Beam and the Bose Smart Soundbar 300 are similarly performing 3.0 setups, although some users may prefer one bar over another. The Sonos has a room correction as well as auto-volume feature. However, the Bose is smaller, with a slightly better-balanced sound profile. It can support more audio formats via its HDMI ARC port and it has more wireless playback options. 

Bose TV Speaker

The Bose Smart Soundbar 300 is better for mixed use than the Bose TV Speaker. The 300 has a better center and surround performance. It also offers treble adjustment, as well as more wireless playback options like Apple AirPlay 2. It also connects to the Bose Music app that gives you a bit more functionality.

Bose Soundbar 500

The Bose Smart Soundbar 300 is a better 3.0 setup than the Bose Soundbar 500. The 300 is smaller and able to deliver a better-balanced sound profile. It can get louder with fewer compression artifacts, and it supports more audio formats via its HDMI ARC port. However, the 500's surround performance is better and it offers room correction and EQ presets.

Bose Soundbar 700

The Bose Soundbar 700 is a better 3.0 setup than the Bose Smart Soundbar 300. The 700 feels better built, it supports eARC, and it has room correction as well as EQ presets. It can get louder with fewer compression artifacts, and its surround performance is better.

Sonos Playbar

The Sonos Playbar and the Bose Smart Soundbar 300 are both 3.0 setups but the Bose is slightly better performing overall. The Bose has a better-balanced sound profile, more physical inputs including an HDMI ARC port, and it offers more wireless playback options. However, the Sonos has room correction as well as auto-volume/night more. It also has a better surround performance, even though it downmixes this content into stereo to play it.
