Where the two actually differ on the specs we track (3 of 8). Matching specs are omitted.
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Two whitelisted hands-on testers (Tom's Guide, What Hi-Fi?) reviewed this exact model; neither published lab bench measurements. Both praise the wide, immersive Dolby Atmos soundstage and solid build, but flag a congested/harsh midrange that undermines music and dialogue, and note the AI Dialogue mode can over-compensate. (2 sourced reviews, 2 lab-tested.)
Praised: Wide, immersive soundstage with good sense of height and width from Dolby Atmos; Solid, well-built design with useful, responsive Bose Music app controls.
Flagged: Weak/overstretched bass that muddles or distorts on demanding action content; Congested, harsh midrange and highs; underwhelming for music; AI Dialogue mode can over-compensate and sound hard/forced, upsetting tonal balance.
