Sony HT-A7000 vs Sonos Arc (2022): Dolby Atmos Soundbar Comparison

Both are quite expensive, so not everyone will even consider these for their home theaters. That said, if you are one of those with deep pockets looking to get a high-end soundbar, which of these two should you get? We compare the two below.

The Sony HT-A7000 is bigger and heavier than the Sonos Arc, but they both feel and look like premium products.

There’s a small LCD screen on the Sony HT-A7000 (top) to indicate the source and on the Sonos Arc (bottom), there’s a single light that changes color depending on the input source.

Both soundbars are quite large. The Sony HT-A7000 is 51.25 inches wide, 3.25 tall and 5.63 inches deep. It weighs 19lbs so it’s quite heavy as well. On the other hand, the Sonos Arc measures 45 x 3.4 x 4.5 inches so it’s not as wide and deep, but it is taller. As it is a bit more compact, it weighs less, at 13.78lbs.

When it comes to build quality, both are excellent. They are made of mostly plastic, but they still feel like premium soundbars. The Sony HT-A7000 has a glass plate on top, fabric coverings on the upfiring speakers and a metal grille to protect the front speaker drivers. Meanwhile, the Sonos Arc has plastic grilles at the front and at the sides to protect the drivers. Although the two have solid builds, we have to give the advantage to the Sony HT-A7000 here.

Both soundbars can be bought as a single unit only, or with add-on subwoofers and rear channels. The Sony HT-A7000 is only available in black whilst the Sonos Arc can be purchased in either black or white.


The Sonos Arc delivers better surround sound than the Sony HT-A7000.

The Sony HT-A7000 (left) is shaped like a bar whilst the Sonos Arc (right) has an oval shaped design.

Out of the box, the Sonos Arc sounds a tad better than the Sony HT-A7000. They both lack low-bass, so scenes in movies or TV shows with a lot of action will lack rumble. But this is expected of soundbars. Where the Sonos Arc shines is in crispness and clarity of dialogue. It produces intelligible dialogue, whereas the Sony HT-A7000 produces dialogue that seems to be bass-heavy, and thus, a bit hard to hear.

Another area where the Sonos Arc performs better is in surround sound reproduction. It has side-firing speakers to simulate surround sound whereas the Sony HT-A7000 has front-firing speakers. The Sonos Arc can simulate directional sound more accurately. As for Dolby Atmos performance, both are decent enough, but the upfiring speakers don’t get loud, so they may lack volume and impact.

One thing that the Sony HT-A7000 does have is its EQ presets. You can tweak the sound using the presets—Music, Standard Surround, Cinema and Auto Sound. These presets improve the sound enough to match the source. The Sonos Arc also has its Trueplay Room Correction setting, but this is only available when the soundbar is paired with Apple devices, so it’s a bit limited.


The Sony HT-A7000 supports more audio formats than the Sonos Arc.

A look at the insides of the Sony HT-A7000 (left) and Sonos Arc (right).

As far as features go, the Sony HT-A7000 has the advantage over the Sonos Arc. It supports more audio formats that include DTS, DTS HD High Resolution Audio, DTS-HD MA, DTS ES, DTS 96/24, DTS:X, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, Dolby Atmos, Dolby Dual Mono and 5.1 PCM.

Meanwhile, the Sonos Arc supports Dolby Atmos, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS and 5.1 PCM.

Both of these soundbars come with their respective companion apps. The Sony Music Center app allows you to control some of the features of the soundbar, but not all. You’ll still need the included remote controller to have access to all of its features. In contrast, the Sonos S2 is an all-in-one app that gives you access to all the features that the soundbar has, including its built-in voice assistant.


The Sony HT-A7000 has more ports and it can act as an HDMI hub if you have multiple devices while the Sonos Arc only has a lone HDMI port.

Aside from having more input and output ports, the Sony HT-A7000 also comes with a remote controller.

When it comes to connectivity, the Sony HT-A7000 is the clear winner. Not only does it have more physical ports, it also offers better wireless connectivity for streaming. It has one HDMI eARC, two HDMI ports, one optical and one 3.5mm analog port. It also supports Bluetooth and WiFi connectivity with built-in Chromecast and Apple Airplay 2 and Spotify Connect support.

You can use the Sony HT-A7000 as an HDMI hub for game consoles, Blu-Ray players and more.

On the other hand, the Sonos Arc only has one HDMI eARC port and a single ethernet port for its physical connectors. It’s clearly lacking in this area when compared to the Sony HT-A7000. As for wireless playback, it only supports WiFi—no Bluetooth.


The Sony HT-A7000 is more feature-packed while the Sonos Arc sounds better out of the box.
