Bose's flagship Dolby Atmos soundbar delivers a spacious and detailed sound as well as top-notch aesthetics. This might be one of the best-looking soundbars we've ever tested, and while we wish it committed to Atmos more, we certainly appreciate its clear and present sound.
- Expansive breadth
- Sleek design
- Clear vocal projection
- No DTS support
- Noticeably processed sound
- Not as Atmos-y as the best
Can't decide between the Bose Smart Soundbar 900 and the Sonos Arc? We don't blame you. With both soundbars offering a wealth of immersive audio features and greater compatibility with their respective multiroom platforms, the Soundbar 900 and Arc are two closely matched Dolby Atmos soundbars. Both manufacturers also have plenty of skin in the soundbar game, so know that whichever one you go with, you should be in safe hands.
That being said, we've tested both of these premium soundbars, so we're well-placed to reveal their pros and cons, and guide you to which one you should ultimately buy. Read on for the ultimate Sonos Arc vs Bose 900 comparison...
Let's start with Bose's offering. The Dolby Atmos-capable Bose Smart Soundbar 900 arrived in September 2021 and immediately impressed us. Bose describes it as an "all-in-one powerhouse that replaces the Smart Soundbar 700."
The Sonos Arc is the older soundbar here. It debuted in June 2020 and, like the Bose, supports Dolby Atmos surround sound. In our test we found it supremely capable, producing a detailed, weighty sound.
We're big fans of both products, but let's take a closer look at how these premium soundbars compare in terms of design, price, features and performance...

Sonos Arc vs Bose Smart Soundbar 900: price
We tested the Bose Smart Soundbar 900 at £849 / $900 / AU$1399. But such is its popularity, the price has risen to £899 in the UK as of November 2022. Discounts are becoming more frequent with age, meaning you should be able to find the Bose for under £800 if you shop around.
The Sonos Arc has been on sale for well over a year and usually goes for £899 / $899 / AU$1499. It's still held in very high regard, but you might spot a discount in today's best Sonos Arc deals.
Price drops notwithstanding, the Bose Smart Soundbar 900 undercuts its main rival in the US and Australia.
*Winner* Bose Smart Soundbar 900
Sonos Arc vs Bose Smart Soundbar 900: design
The Sonos Arc is specifically designed to partner with bigger TVs, hence its width measurement of 114cm (just a bit wider than a typical modern 49-inch TV). Its curvy design helps mask the Arc’s dimensions and makes it look svelte.
The Bose Smart Soundbar 900 is designed for 50-inch TVs or larger and measures 104cm long. It has a very similar eye-catching aesthetic to the firm's Smart Soundbar 700, with rounded corners, a metal grille and a polished, impact-resistant tempered glass top.
Both models feature touch-sensitive controls but only the Bose comes with a separate remote. However, Sonos offers a comprehensive app that can be used to control the soundbar, as well as set the device up and enable Trueplay.
Both can be controlled through Alexa and Google Assistant but the Bose boasts an added bonus: Voice4Video. This feature further expands Alexa's capabilities by enabling users to turn on and control their TV or satellite box using their voice.
If you have a low TV, or are just short on space, the Bose 900 could be the best option for you. Not only is it shorter, it's also lower (5.8cm vs 8.7cm). That said, both models look suitably premium and are available in a choice of black or white.
Sonos Arc vs Bose Smart Soundbar 900: features
The Sonos Arc's Dolby Atmos sound field is generated by 11 Class D digital amplifiers that power 11 custom drivers. The Soundbar 900 makes do with nine channels of amplification, two fewer than the Arc. It also does away with side-firing drivers (more on this in the 'sound' section below). Instead, Bose's PhaseGuide technology beams multi-directional sound to distinct areas in your room.
When it comes to set-up, the Sonos Arc uses Trueplay to measure how sound reflects off your walls. The software fine-tunes the speaker to max out performance according to the shape of your room. Bose goes further. The Smart Soundbar 900 comes with a headband with a microphone on the top. Pop it on your head and Bose's ADAPTiQ room calibration software brings out the best in the speaker. Will you look silly wearing the headband? Probably, but it's an effective system.
Whichever soundbar you choose, you won't be short of connections. Both are wi-fi enabled and support HDMI eARC, Apple AirPlay 2 and Spotify Connect. One feature that the Bose 'bar offers that the Sonos doesn't is Bluetooth. Most folk stream music over wi-fi these days, but it's worth bearing in mind.
Both these premium soundbars can be supplemented with additional surrounds or a subwoofer, and both can be grouped with their respective brand's smart speakers as part of an integrated multi-room set-up. However, Sonos offers a far wider range of speakers, including affordable options in the Ikea Symfonisk series.
In summary, each soundbar has its own unique appeal. The Bose 900 offers extra connectivity and cutting-edge sound calibration, while the Sonos can be more easily expanded into a top-notch multi-room system.
**Winner** Sonos Arc
Sonos Arc vs Bose Smart Soundbar 900: sound
The Sonos Arc sounds exceptionally spacious and weighty for a device of its size, stretching right across the front of our test room and delivering bass with a depth and authority.
It uses Dolby's 3D sound technology to great effect and, with a recent software update adding functionality to adjust height volume via its mobile app, delivers one of the most convincing Atmos presentations of any soundbar we’ve heard. There's a slight lack of directness to music, but that's really our only criticism of the Arc's sound.
With an impressively wide soundfield, clear forward projection and bright character, many listeners will likely be very pleased with the cinematic performance of the Bose Smart Soundbar 900. However, the sound doesn't extend outwards as much as we'd like. Of course, it’s a big ask to expect any soundbar to deliver height in the way overhead speakers do, but the Sonos Arc’s performance is much stronger in comparison. Musical delivery with the Bose is a mixed bag, too.
So, if you’re looking for the best-sounding Dolby Atmos soundbar, we’d suggest spending a small amount extra for the added height, transparency, musicality and dynamics of the Sonos Arc.
**Winner** Sonos Arc
- Best Sonos alternatives: budget and premium multi-room systems
There's case to be made for both of these soundbars. The Bose Smart Soundbar 900 is neater and sleeker, and features a beautiful glass top. It also comes with a remote, offers some clever calibration tech and supports Bluetooth. Sound is crisp and detailed, but the the lack of sideways-firing drivers does limit the soundstage when it comes to Dolby Atmos content.
The Sonos Arc might be a bit older – and a bit pricier – but it's also the better-sounding product here. Indeed, it's still the best Dolby Atmos soundbar we've heard at this particular price point. You're not just buying a soundbar, either – you're buying all the usual Sonos smarts and perks, including the ability to integrate it seamlessly into a multi-room system. If it's within budget, the Sonos Arc is the one to beat.
