Today we're comparing two popular soundbars that take different approaches to delivering immersive home theater audio: the premium Bose Smart Ultra Soundbar
($699) and the value-focused JBL Bar 300
($349). Both aim to upgrade your TV's sound, but they take notably different paths to that goal.
The era of thin TVs has left us with underwhelming built-in speakers that simply can't deliver the audio experience that modern content deserves. Today's soundbars have evolved far beyond basic stereo upgrades, now offering immersive surround sound simulation, height effects for Dolby Atmos content, and smart features that integrate with your home ecosystem.
The Bose Smart Ultra
leverages advanced signal processing and more sophisticated speaker arrays to create a wider, more refined soundstage - that's the perceived width and depth of the audio presentation. Its AI-powered dialogue enhancement is particularly noteworthy, using machine learning to identify and clarify speech without compromising other sounds.
The JBL Bar 300
takes a more straightforward approach but still impresses with its MultiBeam technology, which reflects sound off your walls to create a sense of space. While it can't quite match the Bose's sophistication, it delivers punchy bass that's surprising for its size and price point.
Both soundbars support Dolby Atmos, which adds height effects to create more immersive sound, but they handle it differently:
For larger rooms (over 300 square feet), the Bose Smart Ultra
has a clear advantage with its more powerful amplification and better sound distribution. It fills spaces more evenly and maintains clarity at higher volumes.
The JBL Bar 300
excels in small to medium rooms, where its compact design and focused sound projection work to its advantage. It's particularly good for apartments or smaller living rooms where space is at a premium.
Both soundbars offer voice assistant support, but there are important differences:
Modern connectivity is comprehensive on both:
The Bose edges ahead with better multi-room audio capabilities and a more refined app experience.
The price difference between these soundbars is significant - nearly $350. This leads to some important value calculations:
The JBL Bar 300
delivers roughly 70-80% of the Bose's performance at 50% of the cost. For many users, especially those with smaller rooms or more basic needs, it represents the better value proposition.
The Bose Smart Ultra
justifies its premium price through superior sound quality, better processing, and more refined features. If you're building a serious home theater setup or have a larger space to fill, the additional investment may be worthwhile.
The Bose uses custom-developed spatial audio algorithms and PhaseGuide technology to create precise sound placement. This becomes particularly noticeable with content like action movies, where sounds can appear to come from specific points in your room.
JBL's MultiBeam technology is effective but less precise, creating a more general sense of surround sound rather than distinct audio positioning.
Both soundbars handle movies well, but their strengths differ:
For music, the differences become more pronounced:
Both units offer room calibration features:
Both the Bose Smart Ultra Soundbar
and JBL Bar 300
receive regular firmware updates that have improved their performance since launch. The Bose has seen particularly meaningful improvements to its dialogue enhancement features, while JBL has refined its sound profile through software updates.
The soundbar market continues to evolve, but both these units represent solid choices in their respective price categories. The Bose remains one of the best single-unit solutions available, while the JBL offers impressive performance at a more accessible price point.
For most users, the decision will come down to room size and budget. The JBL's value proposition is hard to ignore for smaller spaces, while the Bose's superior performance justifies its premium price for those with larger rooms or more demanding audio needs.
