These are not perfect as headphones go, but they are literally the nicest noise cancelling headphones that any amount of money can buy. They have their ups and downs. I'm going to talk in depth about each of these, but overall these are the best noise cancelling headphones money can buy, so even when it comes to their downsides, you can't do better. First, if you're a regular consumer, you'll be blown away by the sound quality. However, if you're an audiophile used to audiophile grade open back headphones like the Sennheiser HD800, these fall short of audiophile levels of sound quality. Let me explain why that is. Sound quality wise, the sound quality is overall spectacular, but it has two problems. Bass is way overemphasized, and the treble is rolled off. The treble issue is in my opinion the only really major flaw you have to deal with in these headphones. It's really a shame. Even with EQ, there's no good way to make up for the treble problem because the high end is just always a little lacking. Bass is massively overemphasized, but everyone seems to do that these days, and most people seem to love it. Thankfully, you can just lower the bass in the EQ and it works fine, but from an audiophile perspective it's still a mark against it. You can also raise the bass if you want to lose your hearing and cause brain damage from the thump. These things will thump so hard that it'll give you a concussion. Aside from those two downsides, instruments sound absolutely spectacular with amazing definition, separation, and clarity, it's just really unfortunate that they rolled off the treble. It'd be nice if the bass wasn't so overemphasized, but the bass at least is understandable since it seems to be what most people want. I will say however that the mid is absolutely spectacular, so there's that. Even at their best, if you're a real audiophile, these don't hold up to the sound quality of high end audiophile open back headphones by Sennheiser like the HD650 or HD800. These are consumer grade, very top end consumer grade, but they don't reach the heights of real audiophile territory. For most people though, these will blow you away. Noise cancelling wise, these are the best money can buy. I've tried other noise cancelling headphones, and these destroy everything that I've ever tried. It's a night and day difference in terms of the overall quality and effectiveness of the noise cancelling compared to other noise cancelling headphones. However, they're not totally perfect. I have a bunch of air filter fans running full blast all the time, and it reduces their volume by 90+%, but it's a little inconsistent. Some of the inconsistency comes from just how the headphones sit in my head, if I get them just right, it mutes probably 98% of the sound, but if they're just a little off, it drops to between 90-95%. Sometimes it just seems to work better than other times with no apparent explanation. 90% is still a ton of noise reduction. Be aware though that you can still hear things, they're just quiet. Like if you pass a fan while walking, you can still hear it, it's just quiet. There is sometimes a slight amount of pressure from the noise cancellation, but it's very minimal, and a lot of the time there's actually none. Next, we get into the real premium stuff. You're paying like $400 for this, so let's talk about what you're really paying for: the creature comforts and luxury that get overlooked at lower price ranges... For example, the case for these headphones is simply amazing. It feels extremely premium, it has a nice touch, it's light but durable, it has this lovely leathery material that is a joy to hold. It just feels like a million bucks. Even the zipper is nice! The internal layout is likewise spacious, protective and just overall very high quality. Same with the headphones themselves. As an object that you hold in your hand, these things simply feel incredible. They're unbelievably light, I don't know how they made it feel this light. The headband literally feels like a cloud, it almost melts in your hand. I've never felt anything like it. It is insanely soft with this beautiful smooth leather feeling, yet it doesn't collapse when you wear it. I don't even understand how that works, but it does. These are the most comfortable set of headphones I have ever put on my head by far. It feels like you're wearing a cloud. It's crazy. The clamp force is so low that I can wear these for hours and hours on end and they just feel insanely comfortable the entire time. Even just holding these headphones physically, they feel like a million bucks. Like they've got these buttery smooth moving collapsible cans, yet they feel solid and durable, and they have this lovely smooth feeling to them. These are the things you're really paying for when you pay $400. It's just all those little details and luxuries that really make it. They put a lot of luxury into the things outside the actual speakers, and it shows. They feel super premium in your hands, they're a beautiful shape, they're insanely comfortable to wear, they have this elegant simple design to them, and their case is outstanding. Seriously, if you hold the case and headphones of any of the other noise cancelling headphones in your hands, they just don't feel as nice as this. Overall, I really wish they hadn't rolled off the treble. That's its one major flaw. However, these are so good that I can't go back to anything else (other than my open back audiophile sennheisers for serious listening). These are like the ultimate casual headphones for every day use. Watching TV? Use these. Going on an airplane? Use these. Going to the gym? Use these. Going for a walk? Use these. Unless all you want to do is sit down and seriously listen to some high quality music in a quiet room with audiophile headphones, you should be using these. These are your ultimate every day use headphones. If you're a normal consumer who doesn't care about audiophile grade stuff, these will absolutely blow your mind. Even if you're an audiophile, you'll probably end up addicted to them for every day normal use. I'm kindof addicted to them myself, to be honest.

These are the best headphones I’ve ever purchased. They tick all the boxes for me. I’ve previously used the Sony XM4 and Beats Studio 3 Pro, but the Bose is simply a cut above them. Noise Cancellation: The best in the market—no other headphones come close. Lightweight and Comfortable: These headphones are incredibly light, with soft ear cups and a super-light headband that makes them a pleasure to wear. Sound Quality: Initially, I had issues with loudness and bass. However, after upgrading my phone to Bluetooth 5.3, I finally realized why these headphones are considered the best. The sound is crisp, allowing you to hear every single instrument in a track. The bass is amazing. As someone who mostly listens to hip-hop, these headphones deliver and more. Call Quality: The audio quality for calls is impeccable. Long-distance calls no longer feel like a hassle. Battery Life: The 24-hour battery life is more than sufficient for my needs. Portability: These headphones come with a compact case, which was a major requirement for me. They are easy to carry while traveling, unlike the Sony XM5. Controls: The minimal controls on the headphones make them easy to handle. Many of my friends prefer the clicky buttons from earlier Bose versions, but I’m all for this variant. Price: While the price is on the higher side, the quality is absolutely worth it. I managed to get them with a $100 discount. Look out for similar deals, as they pop up from time to time. Overall, I am absolutely satisfied and delighted with these headphones. You simply can’t go wrong with them.

I have been waiting for quite awhile to purchase these headphones. Jumped on the Diamond edition 60th anniversary pair on sale. I had been a consumer of a competing brand and had a couple of issues that I wasn't satisfied with. So, I decided to try Bose for the first time. Cons: 1. The app isn't very good. I like to tinker with the equalizer. And there is one - but it's not very tinkerable. 2. Battery life. It hasn't been a problem yet, but it's much than the last two headphones I've purchased. it has a trick to save battery life. And my primary usage should make it fine. But, if I traveled more, I'm sure it might be an issue at some point. Pros: 1. They are light and comfortable. These are more comfortable than the brand I used to own on the top of the head. My ears don't get uncomfortable (so far) with extended use. 2. The multipoint hookup is flawless so far. Hooks to my computer and phone quickly. Headphones go into sleep mode as soon as you take them off, which pretty much negates the battery problem. As soon as you put them back on, everything hooks back up. 3. Noise canceling is the best ever. The brand I used to own had it. It was great. Outstanding. This is AS good if not better. My wife has been talking noise to me all day. Haven't heard any of it. Win! 4. The big one for me - immersive audio. I thought it was a gimmick. Not something I even considered in weighing my choice. But, the "still" immersive audio is my favorite thing I think. It sounds like I'm not wearing headphones. The sound fills like I'm listening on speakers full blast. When I turn my head, the sound doesn't move with my head. It stays stationary. So it's like sitting 4th row of a concert. The guitarist is over on the left side of the stage and if I move, he doesn't. Basically, I was told all this by reviewers but really didn't understand just how cool it is. I'm happy. Merry Christmas to me.

*Please be aware this review is being written from a totally blind person's perspective. * As I’ll be one of the first to review these headphones due to how new they are, I’ll try to go into as much detail as possible. First off, upon opening the box, you are greeted by a simple layout. The box purely contains the case and the manual. The case is more of an oval shape compared to the NC700, which is more of a square. Inside the case you’ll find the headphones, USB C to A charging cable and an audio cable if you want to connect it to a wired source. Opening the case up, the headphones feel very sleek, around the same size as other pairs, but the first thing I noticed was the fact the cushions mould seamlessly with the headphones, creating a complete seal. There is not that tiny gap like on the NC700 and others. What I liked immediately though was the fact the cushions slip into place with the use of six little tabs which simply snap into place. It’s a lot easier, for me at least, than trying to line them up with a tiny crack as with previous designs. When you turn them on, they have to be on both ears to activate, so Bose can use its tuning technology to personalise to the shape of your ears. This has to be done every time you put them on, turning them on with only one earcup in place won’t work. They truly live up to their name of ‘quiet comfort,’ I am wearing them right now as I type this, and you can almost forget you’re wearing headphones, you can hardly feel them, they almost mould to your head. They truly do hug your ears. The most comfortable pair I’ve ever owned. I also like how the Bluetooth and power button is slightly indented, whereas the multi-function button is perfectly smooth. The volume strip is also able to be felt, and I love how you just swipe it with a finger to change the volume, and you can also configure a shortcut to it, in the Bose Music App. Now moving on to connecting them, it’s just the same as with previous Bose headphones. Turn them on, you’ll hear the tone, and then the voice prompt will tell you they are ready to connect. Select your device and away you go. You can also store up to 8 Bluetooth devices in the headphones, which is a nice feature. The noise cancelling is without doubt the best I have heard yet. You can hardly hear anything when it’s on ‘quiet’ mode. You can also adjust the level of ANC you want, plus in aware mode, there are also ‘active sense’ settings, which block out loud noises by briefly turning on ANC, then turn it off again when the sound stops. This is good for if you're in a restaurant and a blender starts up, for example. These also have ‘wind block’ which mutes the microphones for NC while you’re on a call, so you don’t hear the wind against them. The person on the other end will still hear it though. Now the highlight, the immersive audio. I personally think it’s incredible. I’ve heard details in my music I’d never heard before, it gives the song or other content a completely new layer of depth. Bose weren’t kidding about that. I also have the Apple Air pods Max and these knock spots off those for their spacial audio and head tracking. It really does sound like the music is coming from a speaker in front of you, it sounds like the speaker nearest you when you turn your head, whichever way you turn it. I flicked between spacial and stereo, and I tell you what, I’ll never go back. Stereo sounds bland in comparison to this. I will always use spacial now wherever possible. The base is full, as is the treble and mid-range. You don’t miss anything, just like the artist intended. If you’re like me, you won’t go back either! As soon as I heard these were coming out, I just had to get them. It’s my birthday next month and my family said they would pay for them, but I just had to have them now and wow I do not regret it at all, and neither will you! Just one final note, I researched it last night and Bose will be releasing Ultra ear cushion kits for these headphones soon so we can buy replacements, if necessary, mine will probably wear quickly the amount I’m going to use them. I’ll probably use them on my work laptop too. All in all, yes, their pricey, but your ears will thank you, for both the superior comfort and second to none sound at the same time. Worth every penny, happy listening! Edit: (Because I struggled with this too,) if you want to clear the Bluetooth list and start over, press the power and multi-function buttons at the same time for a few seconds while the headphones are on, until the voice says 'bluetooth device list cleared.'

Noise cancelling is beter dan voorgaande modellen. Geluid is goed. Pasvorm is ook goed.

J’ai déjà testé pas mal de modèles dans cette gamme (Sony XM5, AirPods Max, Bose QC45), et pour moi, le QuietComfort Ultra sort vraiment du lot. La réduction du bruit est juste étonnant, bien au-dessus des AirPods Max, même dans des environnement bruyant assez difficile (vent). Niveau confort, c’est un sans-faute : il est super léger, ne fait pas mal à la tête, même après des heures d’écoute, et s’adapte parfaitement au personne qui porte des lunettes (ce qui n’est pas le cas de tous les casques). Côté son, il y a pas mal de basses a la sortie de boîte mais avec l’égaliseur de l’application (très simple à utiliser), on peut régler ça comme on veut. Résultat : un son riche avec et agréable pour tous les styles de musique, par contre j’ai pas ressenti une grosse différence avec l’Aptx adaptatives et sans et le côté immersion plus artificiel que autre chose. La housse rigide fournie est super pratique, bien meilleure que celles des QC45 ou AirPods Max qui est une blague. Je l’ai aussi testé pour le gaming : nickel en solo, mais à éviter pour les jeux multi à cause d’un petit décalage. Au final, ce casque est une réussite, polyvalent et bien pensé. Je suis ravi de mon achat et je le garde sans hésiter !

Great sound, super comfortable for longer listening times, good noise reduction too. The way to turn the sound up and down via sliding your finger over the headphone side is brilliant as well. The USB-C charge port is great for convenience as well. Study the user manual well before use! The button for turning on and off is not as obvious as previous models (it's the blue tooth button held for three seconds), and the more minimalist, multi-function button is hard to remember in how many taps at what time does what... I also found the auto-off function was strangely unreliable, draining the battery in the storage case a couple of times when I was not wearing them. Just learn to turn them off manually. The biggest real negative for me is the changes to the travel soft case they come in, with no outside storage on the case like the previous Quiet Comfort cases had. I used to be able to place a pen, passport and credit card in it, ideal for when flying (really the only time I use them) overseas. That all said, these are much better than the previous Bose QC headphones, if not more complex, just study the manuals first and enjoy their great sound.

I used to wear Beats By Dre, but these are far superior. The comfort of the headband and ear covers are awesome. I can be working out at the gym with loads of noise around me, but utilizing the immersive or quiet mode completely shuts off the distracting noise allowing me to focus on my own music and workout. They are high quality and the protective case that comes with it is 10/10. Highly recommend making the switch if you haven't already. Bose is top tier for a reason.
