Sonos Ace ACEULUS1AGAV

Best-in-class noise cancellation and a magical TV audio swap for Sonos owners, but the mediocre comfort is a real head-scratcher at this price. Buy it for the ecosystem, not the all-day fit.

The ANC here is the real star, landing in the 97th percentile of our database. It's not just good, it's best-in-class, delivering on that '2x more' promise over the original Ace. Battery life is also a standout at 35 hours with ANC on, putting it near the top of the charts. The sound is solid and well-tuned, sitting comfortably above average with a clean, distortion-free presentation, but it didn't blow us away the way the ANC did. The biggest surprise was the comfort score, which landed in a mediocre 30th percentile. For headphones marketed for all-day wear, that's a letdown.

The obvious rival is the Bose QuietComfort Ultra, which will almost certainly beat the Sonos on comfort and match it on ANC, making it the better pure travel companion. If sound quality is your main jam, the Sony WH-1000XM6 (when it lands) or even a high-end wired set will likely outpace it. The Sonos wins on one specific, brilliant feature: making your home theater private. For that alone, it has no real competition, but as a standalone headphone, it's fighting an uphill battle against more well-rounded champs.

At $449, the value proposition hinges entirely on your living room. If you own a Sonos Arc or Beam, the TV Audio Swap feature is a genuine game-changer that no other headphone can replicate, making the price feel justified. If you don't, you're paying a premium for top-tier ANC and battery but getting sound and comfort that are merely good, not class-leading. In that case, it's a harder sell.

The Sonos Ace Ultra is a fascinating headphone. It's a $449 over-ear that absolutely nails noise cancellation and battery life, but the real reason you'd buy it is the Sonos ecosystem trick. If you already have a Sonos soundbar at home, the ability to beam TV audio, Dolby Atmos and all, directly to these headphones with one button is genuinely magic. For everyone else, it's a very good premium ANC headphone that stumbles a bit on comfort for the price.

If you don't own a Sonos soundbar, skip these. The $449 price is paying for a feature you can't use, and you'll get better all-day comfort and comparable sound from a pair of Bose QuietComfort Ultra or Sony's flagship cans. Go get those instead.

The Sonos Ace Ultra is a niche masterpiece. It's a very good headphone with one absolutely incredible trick. If you have a Sonos soundbar and have ever wished you could watch a movie at full volume without waking the house, just buy these. You'll love them. For everyone else, the slightly awkward fit and good-but-not-great sound mean you should probably look at the more comfortable and established competition from Bose or Sony first.
