I have both, get the QCs. They are a little more comfortable and less bulky than the ultras. The noise canceling is very similar. I couldn't tell the difference between the two. The sound is subjective but I can get the QC with tinkering with the EQ the same sound as my Ultras. The controls are much easier on the QC's. The ultras use a touch bar for volume control that can be unresponsive sometimes. The QC are also cheaper. Battery life is the same. The only thing I liked the ultras over the QC was the auto off and on when you take your headphones. When I reach for headphones, 90% of the time I go for the QCs.

r/bose on Reddit: Bose QuietComfort Ultra vs Bose QuietComfort (SC) - REVIEW AFTER USING BOTH
January 25, 2025 -

The preface of this review is that the standard 2023 QC headphones cost 200€, with the QC Ultras costing 350€. I wanted to understand if the extra +150€ could be justified.

Sound: I am no audiophile by any means, but I have very sensitive ears. The sound on the QC Ultra's was a touch better, but to anybody's untrained ears, there is nowhere near a substantial enough difference to call this any more than a tie. Most of the frequency tests I could find online showed minimal differences between the two. I wondered if the difference I could feel was actually placebo based on how both headphones felt different on the head, something I bet is a factor - despite never being talked about by reviewers.

ANC: Again, a very slight increase on the QCU. Then again, the clamping force is stronger on the QCU, so I wonder if this is actually giving the impression of less noise. Both are excellent. I would say the ANC on the standard QC is still an upgrade over the AirPod Max, for those who have tried them.

'Aware-mode': The transparency on the QCU was noticeably better, especially when listening to one's own voice. I wouldn't put it very far behind the AirPod Max transparency, which many consider to be the GOAT. The standard QC's were definitely good enough though - good enough that I wouldn't feel the need to take the headphones off when talking to people (although I often find it is more polite to do this with strangers...).

Comfort: Both are extremely comfortable, as everybody already knows. The clamping force is stronger on the QCU, and it is a tad heavier. This means the QCU does get hotter on the ears quicker. I would definitely give the point to the standard QC here, especially for those with large heads like myself.

Build Quality: both have great build quality. The QCU is a bit better, with aluminium arms and more protein-leather rather than plastic. Personally I prefer an all-black headphone, I wasn't too happy about having satin silver visible on the QCU. The point would still go to QCU, though subjective.

Controls: QCU has the annoying touch capacitive volume which is absolute sh*t. I have medium-length hair, which often covers that area and stops me from using the volume, not to mention when wearing gloves how difficult it is. Even with a bald head, it's hard to get the volume exactly where you want. Standard QC just has traditional buttons, much easier! They also have an easier on/off switch, though I do not understand why they chose to put it in the middle of the cup!?!? Point goes to QC, though I admit the QCU looks cleaner with less visible buttons. Subjective.

Portability: The standard QC's can be ordered with the SC (soft-case) version, which has a significantly smaller profile whilst maintaining decent protection. Personal preference I guess, but for me, the soft case is much better for travelling, especially since it takes up no space without the headphones inside.

QC Ultra Extra Features: I found the immersive mode to me pretty crap. I knew I wouldn't be using it much for music since I am mostly on the move, but I thought maybe it would be good for podcasts. It's not. Voices just sound weird, and actually makes it harder to focus on what they are saying with other distractions around you. Apple does a better job with their Spatial Audio. I'd argue that maybe for watching TV it could be cool, but then again, there aren't many people who use headphones with a TV! QCU also uses a more modern Bluetooth version, I doubt anyone in this price range cares about the difference between Bluetooth 5.1 and 5.3, though. QCU also has head detection, for me it is more of an annoyance.

QC Extra Features: the standard QC comes with an inline microphone attached to the audio cable, the QCU does NOT! This is a big one for those who want to use the headphones for gaming on PC or Console. The QC with their inline mic work great on my Xbox Series X. I have actually gotten rid of my previous gaming headphones. Mystery why the QCU does not have an inline mic included, since they actually also work on the QCU with no problem. QC also has better latency, twice as fast, according to RTINGS.

App: both use the same app and have access to pretty much all of the same important features, like wind-reduction and EQ etc. Both can do multi-point connection.

Conclusion: It is an easy choice to return the QCU and keep the standard QC. The upgrade is absolutely not worth 150€. In fact, the standard QC just wins in most of the categories for me anyway. Better portability / better comfort / better controls / "all-black".

I am in the market for some new headphones. I went and tried on both headphones at an electronics store and the comfort was pretty much the same. The QC Ultras did have a more premium feel but for an extra $130, are the Ultras worth it over the QC? Just wondering if the sound quality is much greater in the Ultras and if Bluetooth 5.3 is worth the upgrade from 5.1 in the QC?

July 7, 2025 -

Just got a pair of QC in white smoke for our daughter and spent some time comparing against my Utras.

For me, the Ultras win in comfort. The earpads and headband cushioning are thicker and more plush. The QCs aren’t uncomfortable, but the thinner cushioning is noticeable.

In our house the ANC sounds and feels the same between the two. Any difference in quiet and aware mode is splitting hairs in a relatively quiet environment.

Both have Bose’s warm sound profile, but the QC is more forward sounding, so the soundstage isn’t as wide as the Ultras. The bass on the QC extends a little lower and has slightly more attack and definition than the Ultras.

The mids and highs are decently represented on both. The QCs are more forward/direct while the Ultras have a more delicate touch with both.

A couple of reviews I watched noted some channel imbalance with the QC and I hear it. Out of the box they favored the right side slightly or quite a bit depending on the song. I did a factory reset which helped, but I can still hear some imbalance and it’s still more prominent on some tracks vs others.

I like both and I think it comes down to preference in soundstage. Those who like a more forward punch may prefer the QC. Those who like more spaciousness may prefer the Ultra. I prefer the Ultras for classical and acoustic stuff, but I’d have no problem using the QC for punchy rock and pop stuff…especially if I were in the mood for more bass.

r/bose on Reddit: Is QuietComfort Ultra good for general gaming?
November 25, 2024 -

I've had many headphones and played different games with them, ranging from battlefield, escape from tarkov, slender the eight pages, and many more. I used Audeze Mobius for example, I loved the 3D audio feature, I also loved how good the mic was. My crusher anc 2's broke last night, and I'm wondering if this headphone is good for gaming? I mean I read that the mic was decent, it has punchy bass, and even has spatial audio. Do any of u have issues with the headphones or do you love it just as much as the people in the amazon and bestbuy reviews do? I already have an arctis nova pro wireless which is my 7.1 headset, though it really isn't that good at it imo and does not fit my head well at all. I guess what I'm wondering is, would it make sense to get these headphones for music and gaming or should I possibly consider going for a newer true surround headset with 7.1 audio like the arctis has?

I'm debating between https://www.bose.com/p/noise-cancelling-headphones/quietcomfort-acoustic-noise-cancelling-headphones/QC-HEADPHONEARN.html and these https://www.bose.com/p/headphones/bose-quietcomfort-ultra-headphones/QCUH-HEADPHONEARN.html?dwvar_QCUH-HEADPHONEARN_color=BLACK&quantity=1 . I currently have the QC45 and want to get an update because I have had them for a while. Are the ultras worth the extra $100? I use my headphones for music and noise cancelling and I am interested in the spatialized audio but I don't know anything about headphones. What are the pros and cons? Please dumb it down for me because I literally don't know anything about headphones. Thanks!

Hello guys,

I was plannig to buy the new QC ultra but I was wondering if they are a viable choice for gaming.

I know theres steelsseries and such but as a business person / major gamer i need something that can be ok to use in a boss in front of my employees and good at home to play helldivers.

Will they be good to be on discord? Will I need smt else like an external mic?

I know bose used to have a gaming set for the old QC#% unfortunatley they didn t do it for the ultra tho

I used my QC35 to play Elden Ring and sometimes Fortnite with the mic. For casual gaming at least it works very well, I don't need to buy a dedicated gaming headphone just for that purpose

No, not really; they have a notable delay even when using them wired, making them practically un-useable for anything competitive or anything that has sound cues, so anything outside of really casual gaming. Using them wirelessly is even worse, the "aptX Adaptive" they use requires a dongle with "aptX Adaptive" functionality to use the low-latency mode, which has even more latency than wired, it's right on the top end of what is considered "low latency" and will even in movies make lip syncs and sound notably off, let alone in video games. As for the mic and discord, you would have to use a separate mic as Bluetooth forces a hands-free telephony mode that significantly lowers sound quality when using the mic (this is a Bluetooth limitation, though not a Bose-specific problem like the latency), which is why "gaming" headsets come with 2.4 GHz bluetooth adapters, well that and the lower latency. This is not even mentioning the plethora of quality control and software issues the QC Ultra headphones suffer with. Or that fact that they need to be powered on to be used wired, and the USB C cable can't carry the audio signal (because Bose is gonna Bose), so if you want to use them wired and they are out of battery, you are going to need two separate wires plugged into them.

November 26, 2023 -

Hello community ! :)

I’m looking for a new pair of Headphones. I currently have no headphones and I’m looking for the best first purchase (i’m not upgrading from anything)

I used to have the Sony MX-4 but I didn’t like them because they weren’t comfortable for me and because the mic quality was mediocre.

I’m looking mainly for comfortable headphones with great NC and a good mic. **Note: I wear glasses

I will be using them mostly for long travel (airplane) and work (meetings+music).

I listen to a little bit of everything , I love R&B and EDM.

I’m currently hesitating between the QC45 and the QC Ultra (I don’t think the new regular qc are worth it considering they have the same bluetooth version as the qc45). I did go to the store and tried them on. I find the QC ultra a lot more comfortable but I’m not sure the price tag is worth it…

Where I am, the QC45 go for $300 (black friday deal) and the QC ultra go for $500 (black friday deal).

Thank you for your help :))

TL;DR Just a small town girl, livin’ in a corporate world

r/bose on Reddit: Bose QC25 vs QC Ultra - upgrade? Bluetooth sound quality/latency concerns?
February 29, 2024 -

Hi,

I've been using QC25 for several years now and am really happy with them. However I wouldn't mind an upgrade to Bluetooth, as the cable is a bit annoying sometimes, and I'd welcome it too in case the NC is slightly better (the NC of the QC25 is already really good, but better is always better :) ).

My questions...: Are the QC Ultra really better than the QC25, and in what regards? According to RTings ( Bose QuietComfort 25/QC25 vs Bose QuietComfort Ultra Headphones Wireless Side-by-Side Headphones Comparison - RTINGS.com ) they're pretty similar in sound quality, and the QC Ultra are very slightly heavier and have slightly higher clamping force, which is a minus for me, as weight and clamping force bothers me quite a lot.

Additionally I'd be using it mostly with an iPhone, which according to my understanding, doesn't support Adaptive aptX, so would I be stuck with noticeably bad Bluetooth audio quality and latency? Would I notice lip-sync issues when watching a Netflix movie on the iPhone with the QC Ultra? (I usually do notice these things more than the average person and I care about them, I would say I like good sound & video quality and can hear/see some differences, but I'm not a super extreme audio/videophile either.)

Is the NC in the QC Ultra significantly better?

Would the QC Ultra be a good upgrade for me or do I better stick to the QC25 (which are still great...) and just continue living with the (slightly annoying) cable?

If I sometimes also listen from a PC (where I could use the Bose USB Link thing I guess), would that change things significantly?

Thanks a lot for any input.

February 29, 2024 -

I have / had both the ultra and the QC45 for the last few weeks. I just returned the ultra yesterday and kept the 45. Imo the sound on the ultra is a tab bit better, the bass is deeper but you can EQ the 45 to sound like that. Comfort wise I felt the 45 is more comfortable. Mic usage outdoors is garbage on both. NC is about the same. The immersion mode on the ultra is cool for the first few minutes then you realize it's hit or miss depending on what you're listening to. I found myself turning it off most of the time. Imo the ultra is not worth the price difference. I got both on sale, the 45 for $199 and the ultra for $349. $149 price difference in definitely not worth the minor increase in sound.

r/bose on Reddit: 2023 QC for gaming
December 21, 2023 -

I wanted some wireless headphones for gaming and also personal use so I got the new QC’s. I’ve read in multiple places that they would be too laggy over Bluetooth to game with but I haven’t had really any issues.

I play call of duty multiplayer and warzone. As well as Rocket League and some other games. The sound is synced up to my game just fine.

Im curious if anyone else has had any positive or negative experiences using these for gaming. I also use an external mic so I don’t have to use the mic function on the headphones themselves.

The only gripe I would say is they will randomly disconnect for like half a second here and there. Not a deal breaker just a little annoying. Then they go right back to normal.
