Smart Home Sounds’s review, at 4:20
“Now Sonos say that they have a mechanism in the ear cup that adjusts to equalize pressure and create a better acoustic seal. I have to say, these are probably the best fitting headphones that I've tried.”

What channels said about Comfort and fit (45 quoted)

Bose QuietComfort Ultra

What they praised

“The actual cushion on the headband itself is extremely comfortable and I was going through about four to five hour listening sessions and you kind of completely forget that there's there”

9to5Mac · 0:49 · Oct 2023 →

“One of the major highlights of the Bose quiet comfort Ultra is its superior comfort. The earcups are designed with plush, soft cushions, making them perfect for long listening sessions.”

True Choice · 3:28 · Feb 2025 →

“Where Bose really shines is comfort. These headphones are light, and the plush ear cups make them ideal for long flights or hours of uninterrupted listening.”

Audio Zone · 1:25 · Oct 2024 →

“the Bose QuietComfort 45 takes the crown for its unbeatable comfort, exceptional ANC, and overall value.”

What they criticised

“personally the ear cups created more pressure than the QC45s on my ears, making long-term wear slightly uncomfortable”

Smart Home Sounds · 4:20 · Jun 2024 →

“the first thing that I noticed was how comfortable they are. I mean, they are not a big ear cup by any shape by any shape form or whatever the imagination, but they encompassed my ears quite nicely.”

Jason T Lewis · 1:18 · Oct 2024 →

“And I really feel minimal top of head pressure and clamping force from these so despite the heavy weight I still find these to be pretty much all day perfect for comfort.”

RecordingNOW · 1:26 · May 2025 →

“the headband is no exception it's extremely strong and comfortable. I mean just look at the flex that you get out of this thing. This can fit any head shape or size.”

What they criticised

“Sadly fit is an issue. The headband is excellent, but the ear pads are too small and I found myself squeezing my ears into them affecting their long use comfort.”

Scientific Audiophile · 4:13 · Jun 2024 →

“So the pad opening, it's just too small for my ears. Not only does it clamp onto my earlobes at the bottom, it also mildly crumples the back side of the pinna.”

The Headphone Show · 2:33 · Jun 2024 →

“with the foam padded earcups and headband, alongside a mix of plastic and stainless steel, sometimes feeling a bit weighty.”

Audio Zone · 0:55 · Jul 2024 →

“The issue is that it starts to feel hot and sweaty around the ear cups over time.”

Bose QuietComfort Ultra

What they praised

“From a sound quality standpoint, it is absolutely amazing. Everything is crystal clear. It has both low end and high end which is great to see”

9to5Mac · 3:21 · Oct 2023 →

“for watching video, the Bose is going to be perfect for things like YouTube or watching a movie on my television”

The French Glow · 3:21 · Oct 2023 →

“If sound clarity and long listening sessions are your priorities, Bose has your back.”

Pro Product Comparison · 2:48 · Dec 2024 →

“there you have it the Bose QC Ultra wins this comparison by a good margin because it basically matches the Sonos Ace in everywhere except for having that more premium build quality and look to it.”

What they criticised

“Okay so straight out of the box if you don't do any EQing whatsoever to the Bose quiet Comfort Ultra headphones they sound incredibly middly.”

Mark Ellis ReviewsIncludes a paid ad · 4:18 · Oct 2023 →

“when I first put this on it was just massive thunderous overbearing muddy bloated bloated bad quality base just way too much.”

The Headphone Show · 1:33 · Oct 2024 →

Sonos Ace

What they praised

“The Sonos Ace, on the other hand, aims for a true audio file experience. Sound is incredibly neutral and natural. The bass is tight and accurate, and the mids are clear and detailed. You can hear every nuance in a track, which makes them…”

Audio Lab Pro · 1:37 · Sep 2025 →

“Like I said, I was impressed with the Ace's sound quality. They're very clean sounding with nice detail and sparkle in the treble along with punchy, powerful bass that doesn't get boomy, and they also have a wide sound stage.”

CNET · 8:09 · Jun 2024 →

“These are very good premium noise-cancelling headphones with dynamic head track. They can deliver spacious outside the head sound with a cinematic sense of space.”

CRUTCHFIELD · 0:34 · Jun 2024 →

“the Sonos is pretty good for enjoying dialogue-based media, so like TV shows, movies, YouTube and podcasts it seems to do a pretty good job there.”

RecordingNOW · 10:30 · May 2025 →

and 13 more with something to say here

What they criticised

“I was expecting a little bit more. Like most other Bluetooth ANC headphones on the market right now, they have a very v-shaped sound signature with a big boost in the bass and the treble to the point that I had to turn them down in the EQ…”

Jesse Chen · 7:46 · Aug 2024 →

“If you're someone that likes to turn up your base in your car to plus infinity, just have the maximum base, maybe these are actually for you. I personally don't like it. It sounds too bashey and the base sounds cheap, which I don't like.”

Jon Sine · 4:48 · Jun 2024 →

“So you have relaxed ear game between 3 and 5 kHz, um which can lead to a bit of a muffled presentation overall, but then you have this lower treble peak um which is really weird on this headphone.”

The Headphone Show · 6:01 · Jun 2024 →

“As for sound quality, I'm going to have to give these a 6.5 out of 10. Let's face it, the sound quality is underwhelming compared to the standard that we have been accustomed to by Sonos products.”

What channels said about Design and build quality (27 quoted)

Bose QuietComfort Ultra

What they praised

“the ultra is up I would say it's it's the I guess it's Ultra it's like their most high-end headphones that you can get with some new technology in it”

Tech By Leon · 0:22 →

“The most notable difference design wise is the QC Ultra's dual hinge that allows it to fold down a little bit more compact compared to the Ace,”

CNET · 0:56 · Jul 2024 →

“The advantage here is the QC Ultra can fold and collapse so thus it has a smaller footprint and it's clear that Bose designs their headphones for frequent flyers and travelers in mind”

RecordingNOWPaid promotion disclosed · 2:20 · May 2025 →

“I do have to give it to the Bose. I think the Bose is probably the most versatile in terms of design, uh maybe not aesthetics, but it is versatile and it handles pretty well.”

What they criticised

“the metal hinge here is especially annoying because it's got so much resistance that you'll have to hold the headband like this and pull it out one by one”

Kenneth TanakaPaid promotion disclosed · 4:00 · Aug 2024 →

Sonos Ace

What they praised

“The design is sleek and modern with premium materials you can feel. The ear cups use memory foam cushions that mould around your ears without making it feel tight or heavy.”

TC Acoustic · 1:30 · Jun 2025 →

“The Ace headphones sport a look that's both on-trend and timeless. They feel robust and premium. They feel like Sonos headphones should.”

CRUTCHFIELD · 1:32 · Jun 2024 →

“It feels sturdy, well built, you've got the metal rods here for the arms. It's kind of like a more premium feeling Bose 700”

The Headphone Show · 1:51 · Jun 2024 →

“thanks to the minimal design they jump right off the screen immediately giving an elevated premium headset appearance”

What they criticised

“However, it would have been nice to be able to fold the headphones to reduce the size, something that is just now simply not possible.”

“the hinges themselves don't fold in like some other noise-cancelling headphones, like the Bose QuietComfort Ultra”

Jimmy Tries World · 1:20 · Jun 2024 →

“Something I really don't like about the Sonos is that they can't twist and the case is also pretty crappy. I don't like the zipper on it”

What channels said about Noise cancellation (36 quoted)

Bose QuietComfort Ultra

What they praised

“Bose QuietComfort Ultra is unsurprisingly the choice for those who crave the best noise-cancelling tech on the market and a balanced, all-encompassing audio experience.”

Audio Zone · 5:21 · Oct 2024 →

“Now, the noise cancellation on this is excellent. I didn't notice any hissing and it blocks out a good amount of surrounding noise.”

“if noise cancellation, comfort, and mobility are your top priorities, then the Bose quiet comfort Ultra is the way to go.”

Sonos Ace

What they praised

“Despite the sound tuning deficiencies, I actually enjoy using the Sonos Ace. In many ways, it shares the AirPod Max's strengths in terms of ANC and transparency without the crazy weight and in a much better package.”

This is Tech Today · 18:24 · Jun 2024 →

“So, judging these purely as wireless noise-cancelling headphones, I think they hold their own against the competition. If you're already in that Sonos ecosystem, these are a no-brainer.”

CRUTCHFIELD · 5:42 · Jun 2024 →

“Noise cancellation acts very well. I sat outside, there was a bunch of noise going on, my kids were in the pool. It does a great job cancelling out all that noise.”

Stephen Robles · 9:08 · Jun 2024 →

“So for this category of the features, build quality, battery life and noise canceling performance, I'm giving both of these headphones a perfect 5 out of 5.”

What they criticised

“I've noticed they let in higher pitched noises like planking silverware for example.”

6 Months Later · 7:48 · Dec 2024 →

“three anc quirks the noise cancellation is great for low drones engines but it lets in high pitched sounds like clinking silverware or high voices more than the competition does”

Audio Lab Pro · 3:26 · Mar 2026 →

“in comparison to the other three, Sonos active noise cancellation is not as robust as the other three headsets.”

Booredatwork.com · 10:37 · Jun 2024 →
