Short answer: the Sonos Beam (Gen 2). It ranks #9 of 27 all-in-one soundbars by sound quality, rated 3.7/5, at $488; the Sennheiser Ambeo Soundbar Mini ranks #17, rated 3.3/5, and costs $499.95, which makes this an easy call rather than a real tradeoff.
The Sonos Beam (Gen 2) is the better-sounding option. The Beam fits under smaller TVs yet sounds balanced and clear, with dialogue that stays easy to follow. The catch: Atmos height is simulated rather than fired at the ceiling, so overhead effects are subtle.
What the Sennheiser Ambeo Soundbar Mini does well: The Ambeo Mini fits under small TVs and still decodes Dolby Atmos and DTS:X. The tradeoff: There are no up-firing drivers, so height and width depend on processing and the stage stays narrow.
Buy the Sonos Beam (Gen 2). It is rated higher for sound quality than the Sennheiser Ambeo Soundbar Mini and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
