The verdict
The Sonos Ace Ultra don’t venture far from the original Ace in terms of design, but the new 8-band EQ and replaceable battery are meaningful upgrades. You still get excellent ANC and a premium build, but you’ll get the most for your $449 if you already have Sonos gear at home.
✓Liked: Premium build, Excellent ANC, New 8-band EQ, Replaceable battery
✕Could be better: Price, Weight, No IP rating, Best value requires Sonos gear
