Sony Bravia Theatre Bar 7 + S vs Sonos Arc Ultra: which Dolby Atmos soundbar is best?

If you are looking for a way to upgrade from your TV’s subpar audio without taking up space in your home, then a soundbar is a great way to go.

There are a range of options on the market, from budget bars to more premium models. The Sonos Arc Ultra is an example of the latter, and it has snagged a What Hi-Fi? Award for its excellent performance.

Since its release in 2024, the Arc Ultra has been relatively unchallenged. But the new Sony Bravia Theatre Bar 7 + S has stepped into the ring with its eye on the prize.

Boasting both a subwoofer and a soundbar as opposed to the Arc Ultra’s all-in-one design, they are two different beasts. But who will come out on top when it comes to audio performance? We have put both soundbars head-to-head in our test room, so we can tell you from experience which model is most worth your money.

Sonos Arc Ultra vs Sony Bravia Theatre Bar 7 + S: price

So how much will each soundbar set you back? The Sonos Arc Ultra launched at £999 / $999 / AU$1799 but, since its release, you can get it cheaper. In the UK, the Sonos model has dropped to £799 at most retailers, although we have seen it fluctuate.

The Sony system launched at £799 / $1100 (around AU$1320), and has remained at that price since its release. This combo has not been out as long as the Arc Ultra, so there is still an opportunity for the price to drop as time goes on.

There is the option to buy the Bravia 7 without the subwoofer but, for reasons that will become clear, we recommend spending the extra cash.

Right now, though, it is a tie between the two bars when it comes to cost.

Sonos Arc Ultra vs Sony Bravia Theatre Bar 7 + S: design

The two soundbars offer opposing designs that cater to different sides of the market.

The Bravia Theatre Bar 7 + S consists of a soundbar and subwoofer, so there is one extra bit of kit to consider compared to Sonos’ single all-in-one bar.

Offering a versatile design, the accompanying subwoofer is easy to place in our test room and connects to the soundbar quickly. You can use it in two different positions, either with the grille facing the listener or the side of the room.

The Arc Ultra is longer than the Bar 7 soundbar, coming in at 8 x 118 x 11cm (hwd) versus Sony’s 6 x 95 x 13cm (hwd). The Sonos model is also heavier, weighing 5.9kg compared to 4.6kg.

With the Sony bar, you will find a small remote control that puts functionality over style. From here, you can control the power, input, bass levels, volume and turn on Night mode. There’s no such addition with the Sonos, however.

You can find the Sonos bar in either a black or white finish, whereas the Sony system is only available in black. Neither of the bars has a display, and the Sony has no buttons on the top of the bar. The Arc Ultra features touch-sensitive buttons, though these are situated on a ledge at the back. A display with both models would make navigating the settings without relying on the accompanying apps feel more straightforward.

Both designs offer their own benefits. The Sonos offers a slightly simpler set-up with its all-in-one build, but the Sony’s soundbar is more compact and offers versatility with the subwoofer’s placement.

That all depends on what you need from your soundbar, so it’s a draw this time round.

Sonos Arc Ultra vs Sony Bravia Theatre Bar 7 + S: features

In terms of physical connectivity, both bars have an HDMI that supports eARC, but the Sony model has an extra HDMI port.

Dolby Atmos is available with both systems, but the Bravia 7 also offers DTS:X, which provides more options for surround sound.

The Sony bar offers a 5.1.2-channel configuration. Under the hood of the main bar, you will find nine drive units, split between side, centre, up-firing and bass channels. That differs from the Sonos, which is packing a 9.1.4-channel configuration. This is made up of seven tweeters, six midrange woofers, and a 'Sound Motion' woofer.

They both use their company's respective apps. The Bravia Connect and Sonos apps let you fine-tune the settings of the bars. With the Sony’s app, you can also pair the subwoofer (and the surrounds if you have them) from the app, where they recognise the product almost immediately, which makes for an easy set-up.

Both apps are easy to use, but Sony’s user interface is more intuitive and this results in a smoother overall experience.

From both apps, you can calibrate the soundbar to your space (the Arc Ultra employs Sonos Trueplay). Once we have calibrated the bars to our space, we are offered a wider soundstage with both systems. It’s worth noting that the subwoofer is not included in this process with the Sony system, so it must be adjusted by ear using the bass settings with the app or the remote.

There is also the option to expand your set-up with both systems. With the Sony soundbar and subwoofer, you can also add in the Sony Theatre Rear 8 speakers, costing £449 / $500 / AU$599 on their own.

Sonos’ offerings here are more comprehensive, as you can connect other products from the brand, such as the Sonos Sub 4 or the Era 300 speakers. These can be arranged in a multi-room set-up or in one room.

For its more comprehensive HDMI support and better app experience, the Bravia Theatre Bar 7 takes it.

Sonos Arc Ultra vs Sony Bravia Theatre Bar 7 + S: sound

Sony and Sonos take different approaches when it comes to audio performance here. But both are five-star systems that provide a massive upgrade from the majority of TV speakers.

When we start up the Bravia Theatre Bar 7, we are greeted with a punchy, cohesive sound that is immediately likeable. It offers an immersive experience, which is put to the test with Top Gun: Maverick as Maverick attempts to reach hypersonic speed in a jet, and the soundbar stretches the height effects above the TV screen.

The Arc Ultra also impresses, matching the Sony’s sense of scale and punch. Effects sound like they're coming from all around you, and are placed with precision, while certain sounds (like rain) stretch far beyond the confines of the TV to which the soundbar is connected.

Bass performance is strong with both soundbars, but the Sony’s added subwoofer gives it the edge in terms of agility and precision. We also find that the bass is well-integrated with the main soundbar and performs with the same precision as the rest of the system. That’s not to dismiss the Sonos performance with lower frequencies, as the bass it delivers is "tight, tuneful and expressive in a way that is rare in the soundbar world".

We listen to the Bravia Theatre Bar 7 without the subwoofer, and it still delivers clear vocals and convincing height effects. But the sound is thinner and lacks the sense of scale and authority that we get when the subwoofer is added.

Both soundbars produce clear vocals, but the Sonos model produces richer voices that lend a more emotive and warm feel to the sound.

When playing music, this warm approach carries foward with the Sonos to make it a more emotive performer than the Sony. The soft vocals of Aurora’s Churchyard start with the appropriate low-level dynamics and build to the punchy chorus as the bass kicks in. As with the Sony’s performance with movies, the Bravia Theatre Bar 7 + S delivers a more precise and energetic bass than the Arc Ultra.

Both soundbars are excellent sonic performers, but the Sonos bar inches past the Sony system for its warmer overall sound.

Sonos Arc Ultra vs Sony Bravia Theatre Bar 7 + S: verdict

If you are looking to upgrade your TV’s audio and get a more immersive audio experience, then either of these soundbars will deliver. Where the Sonos Arc Ultra offers a warm, spacious sound, the Bravia Theatre Bar 7 + S counters with a more agile and well-integrated bass.

One of their designs might suit you more, but the Sonos Arc Ultra just takes the crown for its richer sonic performance.
