Which is better for movies with Atmos?

The Bose. Its upward-firing speakers bounce sound off the ceiling for real height effects. The Beam Gen 2 decodes Atmos but virtualizes height from a wide array, so overhead cues are less distinct.

Which is better for music and multi-room?

The Sonos Beam Gen 2. It syncs with other Sonos speakers for whole-home audio, and its five Class-D amplifiers and four midwoofers give a wide, detailed soundstage. The Bose stays inside the Bose ecosystem.

Is the Bose worth $10 more?

At $399 at Walmart versus $389 at eBay as of November 3, 2026, yes if you want Atmos height effects, AirPlay 2 and Chromecast. If you already own Sonos speakers, the Beam is the better fit despite the small saving.

Which fits better under a TV?

The Beam Gen 2. It is 2.68 inches tall and 25.63 inches wide, against 27.3 inches wide for the Bose. Check your TV's clearance before buying either.

Which has better dialogue clarity?

Both handle dialogue well. The Bose uses TrueSpace to separate dialogue from effects; the Sonos has a Speech Enhancement setting that boosts voice frequencies. Neither clearly wins.

Do both support voice assistants?

Yes. Both work with Amazon Alexa and Google Assistant. The Bose adds Voice4Video, which lets Alexa control your TV and cable box as well as the bar.

Bose Smart Soundbar vs Sonos Beam Gen 2 Soundbar

Both are compact smart soundbars with voice control, but they solve different problems. The Bose Smart Soundbar adds Dolby Atmos with upward-firing drivers and TrueSpace processing for height effects; the Sonos Beam Gen 2 has no up-firing drivers and fakes height from a wide array, but it is smaller, cheaper, and slots into Sonos multi-room. At the latest prices the gap is small: $399 at Walmart for the Bose versus $389 at eBay for the Sonos. Buy the Bose for Atmos overhead effects and AirPlay 2; buy the Sonos for a compact, ecosystem-friendly bar at the lower price.

Today the Sonos Beam Gen 2 Soundbar costs $10.00 less at its best price.
