QuietComfort Ultra Headphones - Sandstone

To start out, I must say I am very fussy about audio. I have a small recording studio, which I spend at least eight hours a day in. I have three different sets of headphones, which all have a personality of their own when it comes to sound and mixing, I have a couple of Bose speakers which are excellent and have always been impressed with their products. I did not buy these with the intent of mixing, just for listening out of the studio. Most headphones don’t reflect what a good pair of studio monitors produce. These headphones , do an excellent job of reproducing accurate recordings, good and bad. The features of these headphones was really more than I needed, but I was presently surprised how good they sounded. As I have found over the years with Bose, there was always a little problem in the mids, but the clarity was so clear it was a no-brainer. Ever since I’ve started using these I can’t get them off my ears. I started using them in place of my flat response headphones because they give me a good reflection of my monitors. they are extremely comfortable to wear for long periods of time and the features are top-notch in the noise cancellation is about as good as it gets in a set of headphones. The volume control can be a little bit hard to get used to, but the more I use them the easier it gets, as usual. The one thing I don’t really care for and it’s being kind of picky is, I normally will use these with a wired connection in the studio to avoid any latency by using Bluetooth. But you have to have the headphones powered on even when wire direct. My other headphones don’t use any battery power when plugged in direct. Now, if you’re into high-tech, you’re going to love the immersive settings on these cans. I have no idea how they pull this off and it wasn’t the reason that I bought them in the first place, but these things are awesome. I guess there’s no way I can really explain how they work and what it sounds like so I guess you’ll have to buy a pair for yourself. The problem with that is that they are a little pricey as always with Bose, but I think in this case they’re worth it. I was prepared to send these back if they didn’t sound good, simply based on how much they cost , so I was pleasantly surprised and how good they were. If you can get by the price, you will be happy with these headphones. Nothing is perfect, that’s for sure, but in the audio department these things come pretty close….Nice job Bose !

I own the Bose QC45 and have recently tried comparable headphones in this class including the B&W PX7 S2 and Sennheiser Momentum 4. The Bose QC Ultra are probably the best among this group when it comes to my top three priorities - sound quality, comfort, and ANC. Here are my relative rankings in these categories: SOUND QUALITY I was a bit skeptical at first that Bose's new Immersion Mode would amount to a mere marketing gimmick, but it's really unlike anything that I've ever heard. It's hard to describe (you have to listen for yourself!). Immersion Mode somehow gives the sense that the audio source is in front of you (almost like speakers), which ultimately creates a more expansive, 3D-ish effect that makes the music "come alive." I now listen exclusively in Immersion Mode and don't know that I can go back to the more traditional, "closed-off" sound of other headphones. The QC Ultra is a definite step-up from the QC45. I was also impressed with the B&W PX7 S2's balanced and clean sound signature; however, I had to return my pair because the left ear cup suddenly and inexplicably went dead after only a week of gentle use. I contemplated repurchasing because of how good they sound but don't want to take the chance on receiving another dud. While the M4 has a loyal following, I was personally disappointed by the Sennheiser sound signature. The M4 was too bass-heavy for my taste; moreover, the clarity/separation for vocals and instruments was muddy and often overpowered by the bass. Rankings: QC Ultra >= PX7 S2 > QC45 > M4 COMFORT Both the QC45 and QC Ultra live up to the "comfort" in their names. Their light weight and plush padding are second to none, with perhaps a slight edge to the QC45. The PX7 S2 is also quite pleasant to wear but a little heavier compared to Bose. I was not a fan of the M4, which felt a bit cheap to me; the material used for the ear pads was not breathable (think hot ears), and the clamping force was tighter than Bose and B&W. Rankings: QC45 >= QC Ultra > PX7 S2 > M4 ANC Bose has earned a reputation as the "King of ANC", a title that is well-deserved IMO. Both the QC45 and QC Ultra are noticeably more effective at drowning out ambient noise than the PX7 S2 and M4. Rankings: QC Ultra = QC45 > PX7 S2 = M4 Hope that my observations help you if you're trying to decide between these headphone options. I plan to keep the QC Ultra as Bose has made substantial improvements to the QC45, namely the Immersion Mode, that justify the price differential for me. I do wish that the battery life were longer, but its other distinguishing features make up for it. Overall, I'd give the QC Ultra 4.5 (rounding up to 5) stars!

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.

I love them. Many negative reviews were on the foam not lasting and not being able to get replacements. However, the foam part IS NOT meant to last forever and THEY DO sell replacements on here for them. They sound really good, they do block out sound. I fly in 6 weeks to Greece, so I will come back after that and let you know how they did on the plane. From wearing at home, you can hear everything around you if you have a certain option (ALL IN APP) but the have an all immersive that fully blocks out all sound. People around you cant hear what you are listening too either (tested that too). I wear glasses and earings and they fit comfortably over them. When using the right setting it is so quiet if you close your eyes you feel in a zone outside the world, alone, peaceful, and quiet. This is good because when there is alot of noise, I can get anxious from it and need an escape. These will work well. The color is so cool love it, and they have EQ and IT DOES work. They have an easy user friendly app and customizable button. A volume slide bar, you can skip music with it or go back, pause it, answer the phone, answer a second call at the same time. It really is a good buy. I was 100 off when I bought it. Really worth the money. LASTLY they are super light. I and you bearly feel them on your head. I love them and you will too!

So just to preface my friend is a bit of an audio file and has shown me a lot of medium to high end consumer headphones and systems. I've been super cheap myself and only just recently started to try higher and higher end products granted the highest I currently have is a pair of JBL ead buds that I think were around 40-50 dollar mark. (got them on sale might retail higher) So these Bose headphones are quite the step up in price but honestly comparing the two... A DOWNGRADE in sound quality. I don't think the ear buds I'm comparing it to are even that great! I literally just went back and forth between the two with the same connection, audio file, everything, and they just aren't that good! I don't get it. Was extremely disappointed even when I first tried them it was extremely noticeable. Don't get me wrong they are a good set of headphones for around the 50-100 buck mark but that's the problem they are 3x + that budget point! I've been very impressed with speakers from Bose and was just utterly disappointed with these. Idk if the sound cancelling really costs that much because that's really the only outstanding feature that these have. Main gripes: -Price for what they deliver. -They seem to be really proud of their "immersive experience" but they sound like they inject white noise put the audio threw a high and low filter (as much clarity loss than a security camera loosing connection)and then play that audio in an ecco room and they push it to you like the best thing since sliced bread and you know it might be if the music or whatever didn't sound like crap now. Like it could be really cool for immersive binural experiences like that tech has potential to make vr 360 video super immersive but they really do modify the audio too much. -Audio quality: as in the crispness and high tones are worse than what I have and the punchiness of the bass is worse than my ear buds that are like 1/8th the price. The bass itself is also very not present by default and has to be boosted a bit to sound normal and maxed to have it sound good. It can shake or rumble to its credit, and reproduce really low frequencies it's just not as punchy if that makes sense. -Loudness: typicaly I like the 75% volume mark to be a good loud workout/hype type volume(and typically it is) for these that's about 90%. It's max volume is (in most cases/with typical balanced audio) one click too loud. When listening to quiet audio I literally can't turn it up enough which is so annoying. It's like just barely loud enough to be ok for 80% of the time but it's literally just on the line and that sucks. I want to say 90% of the cheaper ear buds can be too loud and give me the controll over how loud I want my music. And like it was very similar with the bass, when boosted it just barely hits that ok level but can't go past just ok. -They don't like to stay on my head. I do have a really small head and I know that less clamp force generaly means more comfort but if you do get these you probably want to because of their insane noise cancellation and if you can only wear them at home not moving much in a chair where it's probably fairly quiet already that's doesn't really seem ideal. Anywho some good points -Very comfortable -Noise cancelation literally sounds like you teleport into outer space - They do sound good and have a warm unique sound to them ($100 dollar good not 300) -Loudness and bass are just so barely satisfactory (for me it's a negative but for you, maybe that's all you need) -Can rumble and shake even if it's just a little bit. (Definitely feels like it's tuned for mid tones the most) -Battery life is good but again it doesn't stand out For the price, the brand name, and the sound quality I am really disappointed. I was very excited to have finally splurged on a really nice pair of headphones to get a taste of some better sound quality but was left with a bad taste instead. It's not impossible that I didn't do something that would have made them so much better or that I was doing something wrong because I only had them for a day or maybe I even got a lemon somehow but they did work so I don't think so.

The differences between these and my spouse's QC45 are hard to spot, making one wonder if they are worth the extra cost. And because of the cost and only marginally better noise cancellation that the Soundcore, I'm rating 4 stars. The app/pairing experience was decent, easy to add to an iphone. Once finally paired, the connection is buggy. Audio quality is good, not great. In some cases, the headphone performance is odd. Using Duolingo and other similar apps, the headphones cut out the audio, announce an incoming phone call, the connect "to the call." Mind you, this is in the middle of a lesson, not between lessons. It works, but is annoyingly odd. I compared the noise cancellation in these to the Soundcore Space One Pro and the Bowers & Wilkins Px*. These performed the best, only slightly better than the Soundcore. I tested all three standing next to a two engines that were idling, one diesel and one V8 with sport exhaust. These could block nearly all of the noise. The Bose excelled. The Soundcore were close to the Bose. The B&W were really poor. The Bose audio quality is good, but not as great as my in-ear Shure SE315. Of course the Shure block all noise by ear plugs, and do not make use of any active noise cancellation, thereby preserving the best audio. The Bose, as good as they are, still distort the peaks of the audio to actively block the noise cancellation. They should be better for the price. Portability is not an issue. They fold flat, and in the case, take up space in a bag, but can be managed along side a laptop. . The Out of Box experience was OK. The Bose and Soundcore have gotten rid of all plastic. 100% recyclable wraps and papers. Not so the B&W. The Bose came 50% charged for easy testing. The box was badly dented. If these were. a gift, I'd have been unhappy to present these. Just because of the best performing noise cancellation and the myriad of flights that I take, I'm keeping these despite the middling audio quality.

Best among all others! Been using a pair of Beats Studio pro for one year and some months but decided now to switch because I needed something more comfortable! I was between this Bose and the cosmos table Sony! I’m glad I chose this one! Super comfortable, perfect sound quality and noise cancellation! You can adjust the modes which is sooo cool! Color is beautiful, I gor the blue ones! Think will be great for exercise because it’s very light and well cushioned! Love it! I recommend them!

I use headphones a lot, especially to listen to music & block out noise while coding. I use them daily. I bought the original Bose noise canceling headphones way back in 2010 and, if I remember correctly, the model was the original noise canceling set of headphones offered. They were great. The noise cancelation worked well and the sound quality was really good. And the headphones lasted well over 10 years. They were rugged enough to survive drops and the rigors of travel inside of a backpack. When they finally died, I replaced them with a set of refurbished, used 2nd generation Bose noise canceling headphones and I was never really happy with them. They had a replacement cord which was a bit too short, too bulky and had a non-functioning volume control on the cord. The sound quality was tinny compared to the first set I bought. They worked and I still have them & use them as backups but I wanted something better. I found the Bose QuietComfort Ultra here on amazon and bought them in June 2024. First let me say these headphones perform flawlessly. The noise cancellation is notably better than any other noise cancelling headphones I've tried. The sound quality is classic Bose. The battery life is excellent and not having to keep AAA batteries everywhere is an absolute plus. The bluetooth functionality is among the best I've used. The fact that it can be used as a corded set is also a major plus. But they are beyond fragile. I had them less than a year when, after having finished using them at my desk, I dropped them on a carpeted floor from a seated position and they stopped working. When the activation button was pressed they would make a funny "bumping" noise and would not activate. The drop was maybe 2 feet. Bose made it right. They sent me a free new pair after I sent them the old pair. They made it easy and I got my replacements quickly. A few days ago, after having used them at my desk, yep - I dropped them. This time I dropped them on a hardwood floor and, even though the drop was (once again) less than two feet, I had a sinking feeling that was confirmed when I picked up the headphones, put them on and pressed the activation button. They came on with the familiar, "Battery 80%" which gave me hope for a fraction of a second, then the strange "bumping" noise started again and, sure enough, they no longer worked. Once again, Bose stepped up when I went to the website and submitted a repair request. They are sending me a refurbished pair of replacements for free. Unfortunately, this is not a viable solution for me. I’m sure this level of customer service has its limits, and I’m concerned for what is going to happen the next time the headphones break. I'm now looking for an alternative solution for when the refurbished pair ultimately break. On another note, I bought a pair of Sony MDR7506 Professional Large Diaphragm Headphones here on amazon the day the replacement Bose pair broke. I got a great black Friday deal on them and received them the same day. They're great and are a fine solution for home. They are actually a much better pair of headphones than I had anticipated. But I still need a noise cancelling set for situations away from home, particularly while travelling. I love my Bose QuietComfort Ultra headphones but, unless Bose finds a way to make a future model more rugged, I'm in the market for a different solution.

*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.'

I waited awhile to review this. I think it's important to be accurate in a review. Fake reviews are evil and go against the spirit of a review, which is to give someone thinking about buying something the correct information. Anyways, the positives of these headphones are the noise cancelling and the sound quality. I have some very good phones to compare these to and the sound quality on these is legit good. The noise cancelling is top notch, at least as far as the tech allows it to go. I work in a loud shop and these do really good on some sounds and not so good on others. But I've tried cheaper noise cancelling phones and these are straight up better. The negatives to these are the price for one. But I guess that's the going rate for good quality phones with among the best if not the best noise cancelling. The other negatives are some quirkiness to the controls. Sometimes they give me trouble turning on. They've always eventually turned on but sometimes I've had to try a few times. That should be fixed in a firmware update, unless it is a problem unique to mine. And the last gripe I have with them is the battery life. I mean, It's stated at around 25 hours. I work 10 hours a day so I have to charge them every couple of days. For the price I would expect maybe a bigger battery. Overall they seem to be high quality and they are comfortable. So in conclusion, if you want to spend the money I don't think you'll be disappointed. The few problems I list are annoying, but not deal breakers, at least not for me.

Some of the best premium headphones on the market Pros • Amazing Sound Quality • Great Noise Cancellation • Long Battery • Incredible color/Design Cons • They do use some plastic in the headphone hinges, which at first I was skeptical of its durability, but proved to be well built. That's still a con, as long term use and plastic might prove to be an issue. • not ideal on hot days, ears will be sweaty... but in colder months and in winter it doubles as ear warmers the cons did not affect my overall enjoyment, and I love them still

Bose has easily the best over the head ANC headphones in the market. This one is even better than the previous models. Great battery life (lasted me a whole 12h flight of non stop ANC use)

Se você tem interesse e tiver disponibilidade financeira, pode comprar, vale a pena! Esse fone de ouvido é sensacional, sempre quis ter um fone com cancelamento de ruído de ponta, mas também sempre tive receio de me arrepender em razão dos preços. O mais barato dessas linhas de luxo é R$1.700 (1000xm4), então não se trata de uma compra que você faz no sábado a tarde despretensiosamente. Mas o preço é justificado (até certo ponto) pela qualidade em geral do produto, o material e construção são de alta qualidade, até o momento (10 meses) não vejo nenhum desgaste externo; A qualidade do som é muito boa, talvez não tanto para audiófilos, mas para o ouvinte comum é perfeita; A bateria é excelente, durando muito tempo mesmo, inclusive me surpreendendo quando tenho que carregar; Ele vem com uma case que é de extrema qualidade e funcionalidade; Tudo nele vale a pena, mas o que se destaca e, o motivo pelo qual provavelmente você pensa em comprá-lo, é o cancelamento de ruído. O cancelamento de ruído nesse fone beira o inacreditável; Já testei o fone no ônibus, avião, carro, escritório e os resultados sempre me impressionam. Por alto, eu chuto que ele deva cancelar uns 90% dos ruídos. Se você não estiver ouvindo nada (música, etc) provavelmente vai continuar ouvindo algum ruído de fundo, mas em um nível bem inferior. Se colocar uma música em volume baixo, só escutará ela. É realmente incrível o poder do cancelamento de ruído do fone, creio que a tecnologia não deva ir muito além disso. O ponto negativo do cancelamento de ruído é que, quando você desativa ele ou tira o fone, tem que ouvir alguns ruídos/sons que não tinha consciência que existiam (ar-condicionado, etc) rsrsrsrsrs. Muito bom mesmo. O único ponto negativo do fone é o preço, e esse é um mega ponto negativo. O preço é muito alto, foi o que eu disse, é um artigo de luxo e, se você só quer ouvir uma música em paz com algum nível de silêncio, existem outros fones de ouvido que vão cumprir a tarefa por uma faixa de preço muito menor, de R$300-600, como por exemplo o fone da JBL ou os da Anker. Portanto, se tem interesse em cancelamento de ruído de ponta e, não vai comprometer a renda do seu ano (porque esse é o período que você vai passar pagando ele), vale muito a pena! É um fone durável e creio que ainda vai valer cada centavo.
