The Bose Smart Ultra Soundbar is a slim Dolby Atmos soundbar that Bose launched in October 2023 as its flagship and the successor to the Bose Smart Soundbar 900, and it remains a strong value in 2026 at discounted prices. It kept the 900’s slim, glass-topped design and added an artificial intelligence (AI) Dialogue Mode that makes voices easier to follow. In 2026, Bose replaced it at the top of its lineup with the Lifestyle Ultra Soundbar, and the Smart Ultra’s price has dropped. This Bose Smart Ultra soundbar review covers its design, features, and sound, how it compares with newer premium soundbars on Amazon, and whether it’s a smart buy at today’s discounted prices.
Quick verdict: The Bose Smart Ultra Soundbar delivers wide, detailed sound, excellent dialogue clarity, and polished smart features in a slim, single-bar package. Its modest Atmos height effects, limited standalone bass, and lack of DTS:X keep it behind the Sonos Arc Ultra, but it’s a strong value when you find it around $650 to $700.

Key takeaways
- What it is: A 2023 single-bar Dolby Atmos soundbar with nine drivers and no built-in subwoofer, which Tom’s Guide and TechRadar list as 5.1.2.

Has the Bose Smart Ultra Soundbar been replaced?
Yes. In May 2026, Bose launched its Lifestyle Collection, led by the Bose Lifestyle Ultra Soundbar at $1,099. T3 describes it as the replacement for the Smart Ultra. It brings a redesigned nine-driver array with QuietPort bass tubes, Bluetooth 5.3, a CustomTune calibration that uses your phone’s microphone, and an AI SpeechClarity mode with three intensity levels. It also expands to a 7.1.4 system with Bose’s new Lifestyle Ultra Speakers and Lifestyle Ultra Subwoofer.
The Smart Ultra is still on sale at major retailers, and Best Buy recently listed it at $699, down from $999. That price gap of roughly $400 makes the older model the better value for most buyers, unless you want Bose’s newest calibration and dialogue technology. See the Bose Lifestyle Ultra Soundbar on Amazon.
Design and build
At about 41 inches wide and just 2.3 inches tall, the Smart Ultra suits TVs of roughly 48 inches and larger, and it sits low enough to avoid blocking the bottom of most screens. A wraparound metal grille covers the front and sides, and a tempered glass panel tops the bar. TechRadar praised the build and finish, but the glossy glass reflects light and shows fingerprints.
The top panel holds two touch buttons, one for the microphone and one multipurpose action button, plus a thin light-emitting diode (LED) light bar that shows status. Two recessed openings near the ends house the up-firing drivers. Bose includes a basic remote, but you’ll handle most settings in the Bose app.
Connectivity and smart features
The Smart Ultra has a single HDMI eARC port, so you connect it directly to your TV’s eARC or Audio Return Channel (ARC) input. It has no HDMI inputs for passthrough, so your game consoles and streaming players must plug into the TV instead. That works well with modern TVs, but the soundbar can’t act as a hub for multiple devices. Tom’s Guide also ran into HDMI Consumer Electronics Control (HDMI-CEC) glitches that powered the bar on unexpectedly with its test TV.
Wireless options are a strength. Wi-Fi supports AirPlay 2, Chromecast built-in, and Spotify Connect, and Bluetooth lets guests stream from any phone. Alexa is built in, and Tom’s Guide found it was the only voice assistant available. You can also group the bar with other Bose smart speakers for multiroom audio and use SimpleSync to pair Bose headphones for private listening.
Setup and the Bose app
You plug in the power and HDMI cables, then finish setup in the Bose app. The app walks you through Wi-Fi, updates, and ADAPTiQ room calibration, which plays test tones while you wear the included headset microphone in several listening positions. Tom’s Guide found that calibration noticeably widened and improved the front soundstage.
After setup, the app lets you adjust bass and treble, change center and height channel levels, switch between sound modes, and turn AI Dialogue Mode on or off. TechRadar noted that Bose’s TrueSpace upmixing processes stereo content whether you want it or not, and you can’t switch it off.
Sound quality
Movies and Dolby Atmos
Bose’s PhaseGuide drivers beam sound toward the sides of the room, so the Smart Ultra sounds much wider than its frame. TechRadar praised its width, detail, and dialogue clarity, but found the vertical height effect modest for a Dolby Atmos soundbar. Tom’s Guide heard convincing Atmos height and decent virtual surround in its room, which suggests results depend on your ceiling and room layout.
Bass
Bass is respectable for a single bar with no subwoofer, but it lacks punch. Tom’s Guide found that the drivers sounded strained and rattled during big action scenes. If you want cinema-style rumble, plan on adding a Bose Bass Module 700, which costs about as much as the bar itself.
Dialogue and AI Dialogue Mode
Dialogue is where the Smart Ultra shines. AI Dialogue Mode analyzes the soundtrack in real time and lifts voices above music and effects, which helps with mumbled lines and loud action scenes. Tom’s Guide found it very effective for hard-to-hear speech, but it over-boosted already clear voices on news broadcasts, making them sound harsh. You can turn it off for that kind of content.
Music
Music is the bar’s weakest area. Tom’s Guide found tracks muddled, with stereo imaging that lacked definition, and TechRadar said TrueSpace processing can make stereo music sound vague and a bit edgy. It’s fine for casual listening, but music lovers will prefer the Sonos Arc Ultra.

- Samsung HW-Q990H: Samsung’s 2026 flagship includes a wireless subwoofer and rear speakers for true surround sound, and it pairs especially well with Samsung TVs. See the Samsung HW-Q990H on Amazon.
- Bose Lifestyle Ultra Soundbar: T3 gave Bose’s 2026 flagship five stars for its wide, tall soundstage and excellent spatial upmixing, though it still lacks HDMI passthrough. See the Bose Lifestyle Ultra on Amazon.
- Bose Smart Soundbar: This smaller sibling keeps Dolby Atmos and AI Dialogue Mode in a shorter bar for less money, which suits smaller rooms. See the Bose Smart Soundbar on Amazon.
Who should buy the Bose Smart Ultra Soundbar?
Buy the Smart Ultra if you want a single, stylish bar that makes dialogue crystal clear, you value AirPlay 2, Chromecast, and Alexa, and you can find it near its discounted price. It pairs nicely with a premium TV such as the one in our Samsung S90F review or our Sony A80L review, both of which have eARC ports and picture quality worth matching with better sound.
Skip it if you mainly listen to music, want deep bass without buying a subwoofer, or need DTS:X. If your budget is tighter and your TV is smaller, our Bose Solo Soundbar 2 review covers Bose’s most basic option and its newer alternatives. If you plan to wall-mount the bar under your TV, add the Bose soundbar wall bracket on Amazon, and consider a Bose Bass Module 700 on Amazon if you want more low end.
Frequently asked questions
Does the Bose Smart Ultra Soundbar support Dolby Atmos?
Yes, the Bose Smart Ultra Soundbar supports Dolby Atmos. It decodes Dolby Atmos, including Dolby TrueHD and Dolby Digital Plus, and uses two up-firing drivers for height effects. It doesn’t support DTS:X.
What’s the difference between the Bose Smart Ultra and the Smart Soundbar 900?
The main difference between the Bose Smart Ultra and the Smart Soundbar 900 is AI Dialogue Mode, which only the Smart Ultra offers. The two soundbars share a similar design and driver layout. The Smart Ultra adds AI Dialogue Mode, which balances voices against music and effects automatically.
Does the Bose Smart Ultra Soundbar need a subwoofer?
No, the Bose Smart Ultra Soundbar doesn’t need a subwoofer, but it benefits from one. Bass sounds respectable on its own, yet reviewers found it lacks punch during action movies. You can add the Bose Bass Module 500 or 700 and Bose surround speakers later.
Is the Bose Smart Ultra Soundbar still worth buying in 2026?
Yes, the Bose Smart Ultra Soundbar is still worth buying in 2026 at the right price. The Lifestyle Ultra has replaced it, but discounts of $300 or more make the Smart Ultra a better value for buyers who don’t need Bose’s newest features. Prices change often, so check current deals.
Final verdict
The Bose Smart Ultra Soundbar remains a polished, easy-to-use Dolby Atmos soundbar with wide sound, outstanding dialogue clarity, and strong smart features. Modest height effects, limited bass, and weak music playback keep it a step behind the Sonos Arc Ultra and Bose’s own Lifestyle Ultra, but its falling price makes it a smart pick for TV-first buyers in 2026.
