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
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, since it downmixes this content into stereo.
- Outstanding wireless connectivity options.
- Bass adjustment feature available.
- Gets loud.
- No EQ or room correction.
- Lacks low bass.
- Doesn't support Atmos.
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.
- Dialogue enhancement feature available.
- Outstanding wireless connectivity options.
- No EQ or room correction.
- No auto-volume feature.
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, like 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 cannot reproduce a very deep low-bass.
- Bass adjustment feature available.
- Gets loud.
- No EQ or room correction.
- Lacks low bass.
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're looking for a more immersive audio experience from your streaming platforms.
- Bass adjustment feature available.
- Gets loud.
- Lacks low bass.
- Doesn't support Atmos.
