Our Verdict

Sony BRAVIA Theater Bar 9

Sonos Arc Ultra

The Sonos Arc Ultra is a better all-in-one bar than the Sony BRAVIA Theater Bar 9. The Sonos is better built and has a more balanced default sound profile (although the Sony's frequency response can be almost as balanced after some calibration). The Sonos has a wider, more immersive soundstage, plus it can get louder with less compression. That said, the Sony has an HDMI In port with the ability to passthrough 4k signals at 120Hz, making it a great option for gamers that want to use it as a hub between their console and display.
