“I think these sound leagues above the original Ace tho thanks to that custom dual-ring magnet motor. The bass is deep and tactile while the sound stage is far more wide and open in comparison to its predecessor.”— @ventus77777-h on YouTube

“I think not being foldable will eventually be better for durability in the long term”— @RaedVS on YouTube
“Wow the sound quality sounds just like my phone speakers”— @Gpinky765 on YouTube

The most-cited downside of the Sonos Ace Ultra is the TV audio link to a Sonos soundbar drops out, picks up static, or fails to connect for a few owners, and one returned a pair over it. For the Sony WH-1000XM5, it's hinges crack or break, often within a year.
