Sonos Era 300

What works

6-driver array with up-firing and side-firing speakers produces genuine spatial audio — Dolby Atmos placement is audible
Sonos ecosystem integration — pairs with Arc, Sub, other Era units for multi-room and surround configurations
Trueplay acoustic tuning auto-calibrates EQ based on room acoustics using iPhone microphone

What doesn't

$449 is expensive for a single speaker — the spatial audio advantage requires a listening environment that benefits from height effects
Sonos app redesign in 2024 drew significant user backlash — some features were removed in the update
No 3.5mm input — USB-C auxiliary only, which limits analog source connectivity

Bose Smart Speaker 500

What works

Both Alexa and Google Assistant active simultaneously — only Bose offers dual-assistant in one speaker
Built-in display shows album art, artist, and track — Sonos has no display
$150 less than Sonos Era 300 for listeners who want smart features without spatial audio complexity

What doesn't

Stereo image is wide but not spatial — 2-driver design cannot create height effects that Era 300 produces
Bluetooth 4.2 vs Sonos's WiFi 6 — Bose stream quality is limited to Bluetooth codec ceiling
Bose ecosystem is more limited — cannot integrate into a multi-room surround system as effectively as Sonos

Bottom line

Our pick: Sonos Era 300. It edges out the alternative on 6-driver array with up-firing and side-firing speakers produces genuine spatial audio — dolby atmos placement is audible. That said, Bose Smart Speaker 500 still wins on both alexa and google assistant active simultaneously — only bose offers dual-assistant in one speaker — consider it if that single trade matters most for your use.
