The $500-600 soundbar tier is hotly contested, and the Sonos Beam Gen 2 and Bose Smart Soundbar 600 represent two different philosophies. Sonos bets on ecosystem integration and upgrade potential; Bose bets on better sound from a single box. Both are genuinely good. The choice depends on whether you plan to expand your system.
Bose Smart Soundbar 600
The Bose Soundbar 600 sounds better as a standalone unit; the Sonos Beam Gen 2 is the better investment if you'll expand to a full Sonos system.
Specs Comparison
| Spec | Sonos Beam Gen 2 | Bose Smart Soundbar 600 |
|---|---|---|
| Dolby Atmos | Yes | Yes |
| HDMI eARC | Yes | Yes |
| AirPlay 2 | Yes | Yes |
| Ecosystem Expansion | Excellent (Sonos full lineup) | Limited |
| Dialogue Clarity | Good | Excellent |
| Price | ~$499 | ~$499 |
Sound Quality Out of the Box
Bose's Soundbar 600 uses TrueSpace spatial audio processing and delivers a wider soundstage than the Sonos Beam Gen 2 as a standalone unit. Dialogue clarity is exceptional — Bose's center channel processing is some of the best available at this price.
The Sonos Beam Gen 2 sounds very good — particularly for its size — but its spatial audio implementation requires HDMI eARC and Dolby Atmos source material to reach its best. The Bose sounds impressive even on standard stereo content.
For a buyer who wants one soundbar and no plans to expand: the Bose 600 sounds better day-to-day.
Ecosystem and Expansion
The Sonos Beam Gen 2 is designed as the foundation of a Sonos system. Add Era 300s as surrounds, add a Sonos Sub, and you have a full 5.1 Atmos setup that sounds extraordinary. Each component integrates perfectly.
Bose's ecosystem is less developed for home theater expansion. You can add a Bose Bass Module for more bass, but the surround speaker options are limited compared to Sonos's full lineup.
If you know you want to build a multi-room Sonos system over time — soundbar now, surrounds in a year — the Beam Gen 2 is the right foundation. If you want a great standalone soundbar, Bose wins.
Smart Features
Both support Alexa and Google Assistant. The Sonos app is excellent for multi-room management and music streaming. Bose's SimpleSync app is more limited but works well for the single soundbar use case.
The Beam Gen 2 supports AirPlay 2 and works smoothly with other Sonos speakers for multi-room audio — play the same song in the living room, kitchen, and bedroom simultaneously. Bose's multi-room capabilities are more limited.
For smart home integration and multi-room audio: Sonos. For standalone simplicity: either is fine.
The Upgrade Math
Sonos's real pitch is long-term investment. A Beam Gen 2 today becomes the centerpiece of a proper home theater when you're ready. Add Era 300 surrounds ($549 each) and a Sub Mini ($429) and you have one of the best 5.1.2 setups money can buy — all managed from one app.
Bose doesn't have an equivalent upgrade path. The Soundbar 600 is a premium standalone product, and it's excellent as one. But if you buy it expecting to build toward something bigger, you'll hit a ceiling.
Buy the Beam Gen 2 if you're a planner. Buy the Bose 600 if you want the best sound you can get today from one box, full stop.

FAQ
Can you add a subwoofer to both soundbars?
Yes to both. Sonos sells the Sub Mini ($429) and Sub Gen 3 ($749) that pair wirelessly. Bose sells a Bass Module 700 that pairs with the Soundbar 600. Sonos's subwoofer integration is tighter.
Which is better for gaming?
The Bose Soundbar 600's low-latency mode works well with consoles via HDMI eARC. The Sonos Beam Gen 2 also has a TV-optimized mode. Neither is specifically gaming-optimized, but both are significantly better than TV speakers for gaming audio.
