Bose - Smart Ultra Soundbar vs Sonos - Arc (original)

These two are evenly matched on the broad strokes, with the decision sitting on which individual spec advantages weigh more for your use.

The Smart Ultra Soundbar doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.

The Arc (original) similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.

Both ship with comparable total power, dolby atmos, earc, so those specs don't separate the two — focus on the differences below.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
