Our Verdict

Sennheiser AMBEO Soundbar MAX

Bose Smart Soundbar 900

The Sennheiser AMBEO Soundbar MAX and the Bose Smart Soundbar 900 are both versatile standalone soundbars. Thanks to its sub, which is integrated into the bar, the Sennheiser reproduces a more extended low-bass. It also has more sound enhancement features like a graphic EQ and presets, though this may not be worth the value for some users. The Bose is also better built, with built-in voice assistant support. It also has a better soundstage.
