Should you buy it?
Buy the Ace Ultra if you own Sonos speakers: at $449 (Sonos, Oct 8, 2026) it can pull TV audio from a Sonos soundbar and, in an Early Access feature, move music between the headphones and Sonos speakers over Wi-Fi. It lasted 35 h 53 min in one playback test, beating Sonos' 35-hour ANC-on claim, and one lab measured 88.1% less perceived outside noise with ANC on, close to the Sony WH-1000XM6's 87%. Skip it if you don't own Sonos gear, because that ANC is no better than the original Ace's 88%, and the Sennheiser Momentum 5 matches most of its features. It weighs 322 g, has no IP rating, and replacing its battery means opening the earcup with a Torx driver.
Sonos owners who want headphones that tie into their soundbar.
People without Sonos gear, and anyone who wants light, foldable headphones.
