The catch
Sony BRAVIA Theater Bar 8
A second console still needs a suitable TV input or another switching arrangement, since only one source can connect directly.
Side by side
Sony BRAVIA Theater Bar 8 vs Sonos Arc Ultra: Sony fixes a shortage of TV ports, and Sonos can send TV audio to a compatible Ace
Quick verdict
Bar 8 is the pick when one direct console connection solves a TV-port shortage and the TV input, HDMI mode and cables support the 4K120/VRR signal you need. Arc Ultra is the pick when you already own Sonos Ace, want TV Audio Swap and can connect your sources through the TV. Keep its WiFi enabled. Setup through a phone app, an account and the internet is required for both, and so is open placement. Neither base package includes separate rears or an external subwoofer.
Before you buy
Why, and what it costs you
Sony is worth it only when its input solves your real wiring problem
Suppose connecting a soundbar would occupy the TV input your console needs. Bar 8 can put that console behind the bar and still send video to the same TV port, but only when that port and both cable runs support your required signal. If the TV already has enough suitable inputs, Arc Ultra can leave the console connected directly, so Sony’s extra socket does not establish better gaming.
Where this comes from
Sony documents one direct source path along with its HDMI settings. You no longer have to swap a cable or add another switch. This makes no claim of improved frame rate or lower delay.
The catch
Sonos Arc Ultra
There is no direct input for a console or player, so the TV needs enough suitable sockets and has to pass the required audio format.

- The catch
- A second console still needs a suitable TV input or another switching arrangement, since only one source can connect directly.
Sonos Arc Ultra
- Why pick it
- Sonos Ace is already yours, and you want TV Audio Swap. Your sources can go through the TV. You can finish the Sonos phone-app, account and internet setup, keep the bar’s WiFi enabled and give it open placement.

What this page compares
Console routing, Sonos Ace TV listening and the setup checks that can change your choice are what separate Sony Bar 8 and Sonos Arc Ultra.
Bar 8 can help with a crowded TV connection panel. Arc Ultra can preserve a late-night switch to headphones if yours are Sonos Ace. Those are separate problems, and neither advantage matters automatically just because the bar is sold as a premium Atmos model.
Which one fits
Pick the situations that sound like you
The TV’s only available 4K120/VRR-capable audio-return port is needed by one console
If the TV port, HDMI mode and cables support the full required signal, Sony can carry that source through the bar. Finish app setup first. Arc Ultra has no source input to stand in for the occupied socket.

- Caution
You have Sonos Ace and want the TV sound handed to those headphones
Arc Ultra is the supported host for TV Audio Swap. Set up both products in the mobile app, leave WiFi on for the bar and send sources through a compatible TV. Headphones are not included.

You have no interest in Sonos Ace handover and every source fits the TV
Neither of the two headline connection benefits settles this case. Look at placement, complete-system cost and the audio formats your TV passes through. This does not mean the bars sound the same.

In practice
Differences you will notice
Sony is worth it only when its input solves your real wiring problem
Suppose connecting a soundbar would occupy the TV input your console needs. Bar 8 can put that console behind the bar and still send video to the same TV port, but only when that port and both cable runs support your required signal. If the TV already has enough suitable inputs, Arc Ultra can leave the console connected directly, so Sony’s extra socket does not establish better gaming.
How we worked this out
Sony documents one direct source path along with its HDMI settings. You no longer have to swap a cable or add another switch. This makes no claim of improved frame rate or lower delay.
Ace headphones you already own can decide the purchase for another reason
After the connection is configured in the Sonos app, Arc Ultra lets an Ace owner move TV sound to the headphones for private listening. Keep WiFi on at the bar and the products updated. It is a TV-audio handover, and it does not let you stream whatever music is playing on the bar to the original Ace. Bar 8 is not a supported TV Audio Swap host. This reason loses its force if you have no Ace or your TV already provides the headphone routine you want.
How we worked this out
Arc Ultra is among the hosts Sonos lists as supported. According to the Arc Ultra guide, the original Ace handover covers only incoming HDMI or optical TV audio. That workflow is separate from grouped music and from installing surround speakers.
The setup and the room may rule out both bars before sound is the question
The remote supplied with Sony does not get around its smartphone, account and internet setup requirement. Arc Ultra needs app setup too before TV audio will play. If you can’t accept those prerequisites, neither bar fits. Measure open space as well. Sony’s shorter body is no license to tuck its top under a shelf, and Arc Ultra’s guide rules out an enclosed cabinet. A compatible HDMI socket is only one piece of a workable installation.
How we worked this out
The manuals list these as operating requirements, so you cannot treat them as optional conveniences. Wall-mount gaps are different from stand placement, so follow the instructions for the installation you plan.
Plug in your numbers
Is there room for the soundbar under your TV?
Measure the clear space under your TV. Count only the devices you will plug into the soundbar. Leave out the ones already connected to the TV. The numbers below are placeholders until you enter yours.
Sony BRAVIA Theater Bar 8
Passes these checksIt measures 43.31 inches wide and 2.52 inches high, with 1 separate HDMI source input and 4.7 inches of total width to spare.
Sonos Arc Ultra
Fails these checksWith 0 separate HDMI source inputs, it cannot take the 1 device you want to plug into the bar.
Measure the top of an open shelf. This check does not cover enclosed cubbies. Detachable speakers count toward the docked width. Leave extra depth for cables and the TV stand. This checks size and port count only. Dolby Atmos, 4K/120Hz passthrough and the audio formats your TV supports are outside it.
Option A
Sony, HT-A8000
Sony BRAVIA Theater Bar 8
The HT-A8000 is a standalone bar. It has one direct HDMI source input and a separate eARC/ARC TV connection, and setup goes through BRAVIA Connect. Compatible Sony rears and external subs are optional.
- Best for
- You need a direct input for one console, and your TV port, Enhanced format (4K120, 8K) setting and HDMI cables support the signal it requires. Placement is open, and you can complete BRAVIA Connect setup with a phone, an account and internet.
Facts we checked
- Where the console plugs in: One HDMI source input plus an eARC/ARC TV output
- High-frame-rate video path: 4K120 and VRR with the matching HDMI mode, cables and TV input
- Atmos through the TV: eARC TV return, or a compatible source directly into the bar
- Private TV listening with an existing Sonos Ace: Not a Sonos TV Audio Swap host
Option B
Sonos, Arc Ultra
Sonos Arc Ultra
Sources reach the black Arc Ultra through the TV, and after setup it supports Sonos Ace TV Audio Swap. It needs the Sonos app and open placement. Headphones, rears and a Sub are optional.
- Best for
- Sonos Ace is already yours, and you want TV Audio Swap. Your sources can go through the TV. You can finish the Sonos phone-app, account and internet setup, keep the bar’s WiFi enabled and give it open placement.
Facts we checked
- Where the console plugs in: TV-facing HDMI eARC/ARC port, no source input
- High-frame-rate video path: Console video goes directly to the TV
- Atmos through the TV: Compatible ARC for Dolby Digital Plus Atmos, eARC for TrueHD Atmos
- Private TV listening with an existing Sonos Ace: Supported after app setup, with bar WiFi enabled
Spec by spec
Where they really differ
| Spec | Sony BRAVIA Theater Bar 8 | Sonos Arc Ultra | In practice |
|---|---|---|---|
| Where the console plugs in | One HDMI source input plus an eARC/ARC TV output | TV-facing HDMI eARC/ARC port, no source input | One source can sit behind the Sony bar. With Arc Ultra, source connections and video switching are left to the TV. |
| High-frame-rate video path | 4K120 and VRR with the matching HDMI mode, cables and TV input | Console video goes directly to the TV | A video feature the TV lacks cannot be added by Bar 8. A direct console-to-TV video path is not limited by Arc Ultra. |
| Atmos through the TV | eARC TV return, or a compatible source directly into the bar | Compatible ARC for Dolby Digital Plus Atmos, eARC for TrueHD Atmos | Look at the format and the TV passthrough. An HDMI label by itself does not guarantee Atmos from every source. |
| Private TV listening with an existing Sonos Ace | Not a Sonos TV Audio Swap host | Supported after app setup, with bar WiFi enabled | Owning Ace affects this choice only when you really want that TV-to-headphones handover. |
| Initial setup | BRAVIA Connect smartphone app, account and internet | Sonos iOS/Android app, account and internet | A requirement to do first-time setup without a phone, account or network is met by neither. |
| Body and open placement | 1,100 by 64 by 113 mm, before feet | 1,178 by 75 by 110.6 mm | Sony is the narrower one. A body measurement on its own does not establish fit on a shelf or under the TV. |
| Optional surround equipment | Compatible Sony rears and subwoofers | Compatible Sonos pair and Sub | Look up the exact speakers you own. Owning a brand does not by itself make a usable surround system. |
| Exact base package | HT-A8000 bar, remote, cables, feet and wall brackets | Black Arc Ultra bar, power and HDMI cables | Separate rears, an external subwoofer and Ace headphones are missing from both selected packages. Arc Ultra mounting hardware and its optical adapter are separate purchases. |
Trade-offs
What each pick costs you
With Sony BRAVIA Theater Bar 8
- Sonos Ace TV Audio Swap is not hosted by it, and its supplied remote does not get you out of phone-app, account and internet setup.
With Sonos Arc Ultra
- For Ace handover you need headphones you own separately, completed app setup and WiFi enabled on the bar. It is not an original-Ace route for arbitrary music streamed to the bar.
Change of plan
When the answer changes
A single direct console input spares you a TV-port conflict, and the entire 4K120/VRR path is compatible
Go with Sony BRAVIA Theater Bar 8. Go with Bar 8 once you have checked the TV port, the Enhanced format (4K120, 8K) mode and the cables. You still need BRAVIA Connect phone-app, account and internet setup, plus open placement.
TV Audio Swap matters because you own Sonos Ace, and the TV can handle your sources
Go with Sonos Arc Ultra. Arc Ultra is the pick if you can finish Sonos mobile-app setup, leave bar WiFi enabled and meet the TV-format and open-placement requirements.
App, account and internet setup or open-placement requirements are beyond what you can meet
Neither model fits. Sort those constraints out before you pick either one. An included remote or a body that fits on paper does not make them go away.
The selected package has to contain separate rears and an external subwoofer
Neither model fits. Both are bare-bar packages, so that brief cannot be met by either without additional purchases.
Decision guide
Before you buy
Begin with the connections you need to keep. When the TV already handles every source and you do not want Ace handover, these two advantages do not settle the purchase.
What this page can’t tell you
- This comparison covers connections and ownership. No listening test names a winner for dialogue, bass, loudness, surround realism or audio delay.
- No claim is made about current price or stock. If neither the wiring benefit nor the existing-equipment benefit applies to you, compare the complete systems and audition them, and do not treat this page as a universal sound-quality ranking.
