Main trade-off
Sony BRAVIA Theater Bar 8
Only one source can connect directly. A second console still needs a suitable TV input or another switching arrangement.
Head-to-head
Sony BRAVIA Theater Bar 8 vs Sonos Arc Ultra: Sony fixes a TV-port shortage, Sonos can send TV audio to compatible Ace
The short answer
Choose Bar 8 when one direct console connection solves a TV-port shortage and the TV input, HDMI mode and cables support your required 4K120/VRR signal. Choose Arc Ultra when you already own Sonos Ace, want TV Audio Swap and can connect your sources through the TV. Keep its WiFi enabled. Both require phone-app, account and internet setup plus open placement. Neither base package includes separate rears or an external subwoofer.
Before you choose
The reasoning and the trade-offs
Sony helps only if its input fixes your actual wiring problem
If connecting a soundbar would occupy the TV input your console needs, Bar 8 can put that console behind the bar and send video to the same TV port. This works 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.
What this is based on
Sony documents one direct source path and its HDMI settings. The useful outcome is avoiding a cable swap or another switch, not a claim of improved frame rate or lower delay.
Main trade-off
Sonos Arc Ultra
There is no direct console or player input. The TV must have enough suitable sockets and pass the required audio format.

About this comparison
Compare Sony Bar 8 and Sonos Arc Ultra for console routing, Sonos Ace TV listening and the setup checks that can change your choice.
A crowded TV connection panel and a late-night switch to headphones are separate problems. Bar 8 can help with the first. Arc Ultra can preserve the second if your headphones are Sonos Ace. Neither advantage matters automatically just because the bar is sold as a premium Atmos model.
Winner by situation
Start with what you need it to do
One console needs the TV’s only available 4K120/VRR-capable audio-return port
Sony can carry that source through the bar if the TV port, HDMI mode and cables support the full required signal. Complete app setup first. Arc Ultra has no source input to replace the occupied socket.

- Caution
You own Sonos Ace and want to hand TV sound to those headphones
Arc Ultra is the supported TV Audio Swap host. Configure both products in the mobile app, keep bar WiFi enabled and route sources through a compatible TV. The headphones are not included.

Every source fits the TV and you do not want Sonos Ace handover
The two headline connection benefits do not decide this case. Check placement, complete-system cost and the audio formats your TV actually passes. This is not a claim that the bars sound the same.

What matters in practice
The differences that matter
Sony helps only if its input fixes your actual wiring problem
If connecting a soundbar would occupy the TV input your console needs, Bar 8 can put that console behind the bar and send video to the same TV port. This works 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 reached this conclusion
Sony documents one direct source path and its HDMI settings. The useful outcome is avoiding a cable swap or another switch, not a claim of improved frame rate or lower delay.
Existing Ace headphones can decide the purchase for a different reason
Arc Ultra lets an Ace owner move TV sound to the headphones for private listening after configuring the connection in the Sonos app. Keep WiFi on at the bar and the products updated. This is a TV-audio handover, not permission to stream any music playing on the bar to the original Ace. Bar 8 is not a supported TV Audio Swap host. Without Ace, or if your TV already provides the headphone routine you want, this reason loses its force.
How we reached this conclusion
Sonos lists Arc Ultra among the supported hosts. The Arc Ultra guide limits the original Ace handover to incoming HDMI or optical TV audio. That workflow is separate from grouped music and from installing surround speakers.
The setup and room can rule out both before sound becomes the question
Sony’s supplied remote does not remove its smartphone, account and internet setup requirement. Arc Ultra also needs app setup before TV audio will play. If those prerequisites are unacceptable, neither fits. Measure open space as well: Sony’s shorter body is not permission to hide its top under a shelf, and Arc Ultra’s guide rules out an enclosed cabinet. A compatible HDMI socket is only one part of a workable installation.
How we reached this conclusion
These are operating requirements in the manuals, not optional convenience features. Wall-mount gaps differ from stand placement, so use the instructions for the installation you will actually make.
Try your real numbers
Will the soundbar fit under your TV?
Measure the clear space in front of your TV. Count devices you want to plug into the soundbar, not devices already connected to the TV. The numbers below are examples until you enter yours.
Sony BRAVIA Theater Bar 8
Meets these checks43.31 inches wide and 2.52 inches high, with 1 separate HDMI source input. It leaves 4.7 inches of total spare width.
Sonos Arc Ultra
Does not meet these checks0 separate HDMI source inputs cannot take the 1 device you want to connect to the bar.
Use an open top surface, not an enclosed cubby. Detachable speakers are counted in the docked width. Allow extra depth for cables and the TV stand. This checks physical dimensions and port counts, not Dolby Atmos, 4K/120Hz passthrough or your TV’s audio-format support.

Meaningful differences
What changes the fit
| What changes | Sony BRAVIA Theater Bar 8 | Sonos Arc Ultra | Why it matters |
|---|---|---|---|
| Where the console plugs in | One HDMI source input plus an eARC/ARC TV output | TV-facing HDMI eARC/ARC port, no source input | Sony can put one source behind the bar. Arc Ultra leaves source connections and video switching 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 | Bar 8 cannot add a video feature missing from the TV. Arc Ultra does not limit a direct console-to-TV video path. |
| 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 | Check the format and TV passthrough. An HDMI label alone 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 | Ace ownership changes this choice only if you actually want that TV-to-headphones handover. |
| Initial setup | BRAVIA Connect smartphone app, account and internet | Sonos iOS/Android app, account and internet | Neither meets a requirement for first-time setup without a phone, account or network. |
| Body and open placement | 1,100 by 64 by 113 mm, before feet | 1,178 by 75 by 110.6 mm | Sony is narrower, but a body measurement alone does not establish shelf or under-TV fit. |
| Optional surround equipment | Compatible Sony rears and subwoofers | Compatible Sonos pair and Sub | Check the exact speakers you own. Brand ownership alone does not establish a usable surround system. |
| Exact base package | HT-A8000 bar, remote, cables, feet and wall brackets | Black Arc Ultra bar, power and HDMI cables | Neither selected package includes separate rears, an external subwoofer or Ace headphones. Arc Ultra mounting hardware and its optical adapter are separate purchases. |
What you give up
Every choice has a cost
If you choose Sony BRAVIA Theater Bar 8
- It does not host Sonos Ace TV Audio Swap. Its supplied remote also does not avoid phone-app, account and internet setup.
If you choose Sonos Arc Ultra
- Ace handover requires separately owned headphones, completed app setup and WiFi enabled on the bar. It is not an original-Ace route for arbitrary music streamed to the bar.
Recommendation switch
The decision flips if...
One direct console input avoids a TV-port conflict and the whole 4K120/VRR path is compatible
Choose Sony BRAVIA Theater Bar 8. Choose Bar 8 after checking the TV port, Enhanced format (4K120, 8K) mode and cables. You still need BRAVIA Connect phone-app, account and internet setup plus open placement.
Existing Sonos Ace TV Audio Swap matters and the TV can handle your sources
Choose Sonos Arc Ultra. Choose Arc Ultra if you can complete Sonos mobile-app setup, keep bar WiFi enabled and meet the TV-format and open-placement requirements.
You cannot meet app, account and internet setup or open-placement requirements
Choose neither. Resolve those constraints before choosing either. An included remote or a body that fits on paper does not remove them.
Separate rears and an external subwoofer must be included in the selected package
Choose neither. These are bare-bar packages, so neither satisfies that brief without additional purchases.
What matters in practice
Before you choose
Start with the connections you need to preserve. If the TV already handles every source and you do not want Ace handover, these two advantages do not decide the purchase.
What this comparison cannot tell you
- This is a connection and ownership comparison. No listening test establishes a winner for dialogue, bass, loudness, surround realism or audio delay.
- No current price or stock is asserted. If neither wiring nor existing-equipment benefit applies, compare the complete systems and audition them rather than treating this page as a universal sound-quality ranking.
