Short answer: the Sonos Arc Ultra. It ranks #1 of 27 all-in-one soundbars by sound quality, rated 4.1/5, at $1,099; the Marshall Heston 120 ranks #8, rated 3.7/5, and costs $1,299.99, which makes this an easy call rather than a real tradeoff.
The Sonos Arc Ultra is the better-sounding pick. The Arc Ultra fills a living room with clear, well-placed sound from a single bar, and dialogue stays easy to follow with adjustable speech enhancement. The catch: It cannot decode DTS:X, so Blu-ray discs with DTS tracks fall back to a simpler mix.
What the Marshall Heston 120 does well: This is a soundbar that treats music as seriously as movies, and Tom’s Guide named it their favorite launch of the year for exactly that reason. It keeps a wired aux input, which the Sonos Arc Ultra lacks. Watch for: Height effects are modest, and Tom’s Guide found Sonos Arc Ultra more convincing for Atmos movies.
Buy the Sonos Arc Ultra. It is rated higher for sound quality than the Marshall Heston 120 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
