Bose Smart Soundbar 300 Soundbar Review

Tested using Methodology v1.0
Updated Dec 20, 2022 at 12:10 pm
Bose Smart Soundbar 300 Picture

The Bose Smart Soundbar 300 is a smaller and more affordable alternative to some of the more premium options in Bose's lineup. It retains the same sleek, stylish design as other models like the Bose Smart Soundbar 600 and the Bose Smart Soundbar 900, with built-in voice assistant support so you can control it from the comfort of your couch. You can even upgrade it with a separate sub and satellites from the manufacturer. However, this 3.0 setup is best-suited for stereo content, and it doesn't offer Dolby Atmos support to make the most of more immersive formats on streaming platforms.

Our Verdict

N/A Mixed Usage

The Bose Smart Soundbar 300 is a fair choice for mixed usage. It's a simple 3.0 bar that's designed for listening to stereo content, which includes most music and TV shows. Dialogue is clear in the mix, and there's a little extra punch and sparkle to bring voices and other instruments to life. You can adjust its bass and treble, too, though you don't have access to more premium tools like room correction. It's not the best choice for multi-channel content like Dolby Digital, either, since it downmixes this content into stereo.

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.
N/A Dialogue/TV Shows

The Bose Smart Soundbar 300 is satisfactory for dialogue-focused TV shows and podcasts. Thanks to its discrete center channel, its vocal reproduction is really great, and dialogue is clearly and accurately reproduced. You can even use its dialogue enhancement tool to make voices more clear and crisp. However, there's no auto-volume mode, so you can't balance the volume level between commercials and shows like with other bars.

Pros
  • Dialogue enhancement feature available.
  • Outstanding wireless connectivity options.
Cons
  • No EQ or room correction.
  • No auto-volume feature.
N/A Music

The Bose Smart Soundbar 300 is satisfactory for music. Out-of-the-box, it has a slightly V-shaped sound that's ideal for listening to genres with lots of highs and lows, such as rock, pop, EDM, and hip-hop. Voices and lead instruments are clear in the mix, but there's a little extra punch in the bass range, as well as some sparkle in the treble. However, as a standalone bar, it's not able to reproduce a very deep low-bass.

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

The Bose Smart Soundbar 300 is acceptable for movies. For a standalone bar, it does a good job reproducing dialogue, so you can follow along with the action in your top films. That said, 5.1 surround sound formats like Dolby Digital are downmixed into stereo, which doesn't provide the most immersive sound. You can't watch Dolby Atmos content, either, which is a shame if you subscribe to a lot of streaming platforms.

Pros
  • Bass adjustment feature available.
  • Can get loud with minimal compression artifacts.
Cons
  • Lacks low bass.
  • Doesn't support Atmos.
  • N/A Mixed Usage

This soundbar has a decent stereo frequency response. It performs really well for a small standalone bar, with a slightly V-shaped sound profile that's ideal for genres with more lows and highs like rock, pop, hip-hop, and EDM. The extra emphasis in the high-bass adds some punch to the mix, while the peak in the treble makes voices and other instruments sparkle. Of course, without a dedicated subwoofer, you don't feel the deep rumble in the low-bass that's common with bass-heavy tracks like EDM and hip-hop. If you want, you can always add on a separate sub from the manufacturer to improve its low-frequency extension.

The Bose Soundbar 300 has a good stereo soundstage performance. Its soundstage is perceived to be wider than the bar itself, which is pretty impressive given its small size.

The Bose Soundbar 300 doesn't offer as many sound enhancement features as other budget-friendly bars like the Sonos Ray. If you want to customize its sound, there are bass and treble adjustments available, but it lacks an EQ or preset modes. There's an extra feature called Wall EQ advertised to optimize audio quality when the bar is mounted on the wall, but we don't consider this to be an EQ. It lacks room correction, too, so it may sound different depending on the room you're listening in, but at least you can adjust its bass and treble to make up for this a bit.
