Sennheiser Ambeo Soundbar Max vs Marshall Heston 120

Why pick the Sennheiser Ambeo Soundbar Max: The Ambeo Max creates a big, enveloping surround bubble from one bar, with deep bass that reaches about 30 Hz without a separate sub. The tradeoff: It is very large and heavy, so it needs a sturdy stand or wall and a big TV.

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. The tradeoff: Height effects are modest, and Tom’s Guide found Sonos Arc Ultra more convincing for Atmos movies.

Buy the Sennheiser Ambeo Soundbar Max. It is rated higher for sound quality, and the $399.96 saving on the Marshall Heston 120 is not enough to make up the difference.
