Bose QuietComfort Ultra Bluetooth Earbuds, Wireless Earbuds with Spatial Audio and World-Class Active Noise Cancellation, Deep Bass, Up to 6 Hours of Playtime, Black

I purchased the Bose Quiet Comfort Ultra earbuds in the Moonstone Blue color to replace/be a backup to my Samsung Buds 2 Pro earbuds. Like all flagship earbuds/headphones, they ARE expensive, but you have to pay for quality - and if you can get them at a discount, don't hesitate to snag them immediately. THE BOSE APP: The same Bose app works for all of your Bose Bluetooth sound devices. For example, the Bose SoundMax Speaker. The app is necessary to access certain functions/features. For example, these features require the app: The simplistic Equalizer settings, renaming the device (helpful if you have more than 1 connected Bose device, changing/adding Modes (Quiet, Aware, Home, Exercising, etc), testing earbud fit, change the order of cycling between Modes, Turning voice Prompts on/off, and configuring what the long press on each ear does. The app works and is free, though the equalizer is simplistic with only Bass, Mid and Treble plus and minus. I've set mine to -3, +3, -1. Once any setting is changed via the app, the earbuds "remember" the settings and uses them on all devices to which they connect. NOISE CANCELLATION: Bose was correct to make the first word of the product name "Quiet". I have never experienced such complete noise cancellation. At maximum, and without music playing (also possible), it's not unlike what it must be to suffer near-total hearing loss. Any sound you hear is muffled and has an oddly mechanic tone. By far the noise cancellation is the best I've ever experienced. Out of the box the earbuds come with 3 uneditable modes, 2 of which are "Quiet" & "Aware." Quiet is Max noise cancellation and Aware is minimum and, in fact, slightly amplifies sound around you to compensate for having something blocking your ear canal. I was surprised how natural ambient sound is with the "Aware" mode. At the other end of the scale, I'd say that maximum is for when you don't want to hear ANYthing/one around you if you're using a jackhammer to break up your backyard sidewalk. If you're listening to music you won't hear anyone talking to you, possibly even if they are right next to you. SOUND: The sound is classic Bose. By this I mean a little heavy-handed with the bass with clear highs. The mid-range is OK. I knew this going in and compensate for most of this using the Bose app equalizer. Sound can get painfully loud without distortion and bass can be made to make you feel like it's going through your head (if you're into that sort of sensation), all without muddying the sound. BATTERY: I have found that the 6 hour expected battery life with ANC (Active Noise Cancellation) is accurate for the "Quiet" mode of maximum cancellation. I have discovered that you will get more than that if you don't set the noise cancellation to maximum. So only set it to the minimum that you need. In the Bose app and in the voice prompts, battery life is only reported in increments of 10 (10%, 20%, 30%...90%, 100%). FIT: I have unusually sized/irregularly shaped ears and ear canals that has led to so much frustration over the years. What works for one ear will not work for the other. For example, with other manufacturers, I've struggled to get a good fit (both with my senses and the manufacturer's software fitment tests) - even if I buy after-market tips. Bose is the only company for which I can get a fit that is both comfortable (doesn't lead to pain) and doesn't eventually fall out. This is because of their use of fitment bands that go around the middle of earbud in 3 sizes, combined with 3 sizes of tips. FEATURES: Other than the Quiet and Aware modes that cannot be modified in the level of ANC, the level of ANC can be changed to any of about 10 steps of cancellation for any Mode that you add to the list in the Bose app. This is helpful so that you can save battery by only using the amount of ANC you need for your environment. Using the app you can not only add and remove modes to choose from, but using the star/favorite icon in the Bose app you can set which ones are included in the list to cycle between. For new Modes you add to the list - and ONLY those - you can set a custom level of noise cancellation at any one of about 10 steps between off and Full, important to saving battery (see above). I did not play with the Immersion feature as I've never found that battery-hogging feature interesting to me. Oh, it works and it's freaky to play with, but at the end of the day it's a gimmick created by someone with WAY too much software development time on her hands. There is no detection of me talking that automatically switches the buds to "Aware" mode, but this mode is automatically engaged when taking a phone call or when only 1 earbud is inserted. Phone calls are clear and natural sounding both for me and the other person. Multipoint Bluetooth connection can be turned on in the Bose App and works as expected, allowing you to simultaneously connect to more than 1 audio source (first come, first served). Range for Bluetooth is great (as expected). Easily reaches me in the when I go to the ground floor to use the restroom from the basement where I work from home and leave my phone. Even at that range (about 50-70 feet as you walk and about 20 straight line feet traveling through the floor to the restroom). There is no skipping or sound quality degradation. I HIGHLY recommend these earbuds, as they are my new favorites.

I rarely write reviews, due to lack of time and the fact that if a product performs the way it's supposed to, it doesn't deserve my time to review it. For the Bose QuietComfort Ultra Earbuds, I will make an exception. Simply put, they are wonderful - the sound, the noise cancelling, the ease of fit and comfort. A solid product all around. I have never been a big Bose fan. I thought their products were good, but not great and overpriced. I was looking for a pair of earbuds to replace my old faithful Jabra 65T Elites that finally died. They were nearly 4 years old and didn't owe me anything. Based on reviews, I tried the Apple AirPod Pro 2nd gen, the Sony WF-1000XM5 and the Bose. I was interested in the AirPods mostly because of their compatibility with my Iphone and my son's recommendation. I returned them for three reasons. First, to get them to fit with a tight seal was an ordeal. Fifteen minutes of futzing around to finally pass the seal test (and that's with Comply foam tips -- the Apple silicone tips didn't work for me period.) And even after passing the seal test, I did not find the ANC particularly effective. Adjusting the volume by sliding my finger up and down the stem was wonky -- not working, pausing the music or shifting the bud, the seal I worked so hard to get, broke. Also, not having a real equalizer is a drawback. Apple has a customization wizard, but I like to have different settings for different genres of music. The customization wizard uses Apple's own sound track. On to the Sony's. I liked the Sony's. I have the WH-1000XM4 over the ear headphones for serious listening and they are great. But they are not suitable to wear for dog walking, bike rides or the gym. I need earbuds. The over the ears are also bulky to take on airplane flights taking up a lot real estate in my string pack or messenger bag. Anyway, I tried the 1000XM5's and liked them. The sound is very good as is the ANC. The three drawbacks are ease of fit, comfort and volume control. While easier to pass the seal fit test than the apples, it still took more futzing around than I care to do. Also, to pass the seal test, I had to use the large tips which hurt my ears after an hour. Finally, the four tap volume control is a pain. I either got know response or went back a track because I only tapped three times. So on to the Bose. Nirvana. Fit and Comfort. So easy to get a fit with their innovative tip and wing combo. The wings are really a small silicone gasket that fit inside your ear, but outside the ear canal. Select the right combo of tip and wing (sized independently) put them in your ear and you pass the fit test, first time, every time. I hardly feel them in my ears. Sound Quality. Superb. The Bose bathe me with aural warmth. I liked the Sony sound until I listened to the Bose. I would characterize the sound as warm but accurate. The Sony sound is like sunlight. The Bose sound is like an incandescent lamp. Despite the warmth, the sound is always clean and bright when it needs to be. I listen to a very wide range of music and the sound has been great for every genre. I think that classical music really tests the quality of an audio product due to the tonal range of instruments and voices and the variety of textures. Listening to Mozart's Requiem was sublime. It was like falling in love all over again. The immersion sound option raises the sound quality to a whole new level, bringing a depth and presence to the music. Just wow. And unlike the spatial music technology of Sony and Apple, immersion works for all sources. What I said about Mozart applies to any rock, jazz, and Latin that I have thrown out them. I've heard sounds, I've never heard before. The Bose app has a basic equalizer but I leave everything flat. ANC: Can't be beat. I can listen to quiet music while my wife is watching TV and it doesn't bother me. Sharp sounds such as a firecracker breakthrough but it's not a sensory deprivation chamber after all. I remember the early days of ANC -- it deadened the sound. Not these buds. The sound is alive and well. Can't wait to take them on my first flight in two weeks. And the aware mode is terrific. Just switch to aware and have a conversation without taking the buds out or when using them while on a bike ride. Controls: Work really well and sliding you finger to increase/decrease volume is easy, unlike my experience with the AirPod Pros. I learned that the double and triple taps to move forwards and backwards between tracks does not have to be super rapid. Overall, the touch controls work as well as the physical controls of my old Jabra's. Phone calls: Very secondary for me but so far they have worked just fine. I hear voices clearly and it seems that I am easily understood. Battery Life -- The only weakness- 4 hours with immersion on but I'm told with moderate volume, you can eke out 5 hours, enough for a cross country flight. And I will keep my over the ear Sony's up top in my carry on if I need them. I am not too concerned. Not concerned enough to take take a star off. Everybody's tastes are different. Some folks will be wed to Apple and it's ecosystem and the buds are $50 less. Sony has better battery life. But for me, Bose wins hands down for the combination of fit, comfort, sound quality, ANC and controls.

I was forced to buy new earbuds becuase I accidentally left my old BOSE QC earbuds in my pants pocket and washed them. They would eventually power up but would not connect etc. so I opted for the new BOSE Ultra QC earbuds. But, the only thing ultra about these earbuds is that the sound quality is slightly better the the regular QC's and for me is the only Pro in my evaluation. I'll preface this with I use my earbuds on multiple devices. iPhone, iPad and laptop. Let's start with what I hate about the case. 1. Its smaller then the regular QC's which is good for slipping them in your pocket. What I miss in this case is the indicator lights that show you the battery level of the case. The ultra case does not have this and haveing it is very helpful to me. 2. With the regualer QC case you can also toggle between devices with the small button inside the case. Although the ultra case has this button on the back, its pretty much useless and barely has any functions. Its almost wasted effort in designn and manfacturing for BOSE. 2.a With the button on the regular case you can press it once to see what device it is connected to. very simple and very useful. The ultra case does not do this. You have to open the BOSE app on your device to see where its connected AND you have to use the app to change devices. This may be my biggest issue. Its musch easier to just toggle the button on the case while the buds are in your ears to change evices. I don't want to have to get my phone out, open the app, wait for the app to connect , touch the earbud icon to see my choices and select what device I want. I simply want to toggle the button on the case. 3. Trying to withdraw the earbuds from the case is not easy. The only way I can get them out of the case is by tugging on the rubber ear piece. I'm sure over time they will tear apart. This seems to not been thought through by the designers. Now lets go with the earbuds. 1. They are small and I guess that's ok not much of an issue here except for the earpice options. While I have to use the largest option from the choice of 3; even the largest option isn't really big enough. It fits ok but not great. My regular QC's biggest option is larger and fits really good. I'm not sure why they didn't retain the same sizing options for the ultra. 2. While using, you have to luanch the app to see the battery life. With the regular QC's you simply touch the left bud to hear the battery level. Again, very simple and useful. 2.a Lets talk about battery life. While initially I just used my new ultras for conference calls and listening to videos while connected to my laptop and it all seemed good. Then one day, with a full charge, I went for a walk that lasted just over an hour. With about 10 minutes left on the walk I started getting low battery responses. I'm like, no way. I can't have this. I normally have several conference calls that last over an hour and I can't have these dying in the middle of a call. I also travel a lot by air and often have flights over 2 hours. So reason #1 why I returned them. 3. The sound quality is very comprable for both and while the ultra may be slightly better but not worth the extra $$. I'm a sound nut and not opposed to spending extra doe for better quality but not here. Especially with the other issues I have for this version. All in all, I'm very dissapointed in BOSE's effort with the Ultra's. I have a lot of bose items and this is the first time I've been dissapointed in their products. So much so I sent the ultras back and purchased the regular QC noise cancelling earbuds like I had before. Now I'm happy again.

For the last 3 months, I wanted to find a pair of wireless earbuds that were, at the very least, comfortable. My previous pair of wireless earbuds, Sony's WFSP800N were, by far, the most comfortable wireless earbuds I have ever experienced. That being said, they're going on four years old. They disconnected randomly from my phone, they often remained on when I put them in their charging case, and on a few occasions, just my sweat would be enough to trigger the touch sensors and either skip or pause whatever song I was listening to. So, I set out to try just about every major brand that *wasn't* Sony this time around. I tried the top of the line in the $200 price range from Jabra, Beats, and Sennheiser. Jabra was by far the one I wanted to succeed the most. I picked up the Jabra Elite 8. The sound was good. Noise cancelling was automatic and easy to cycle. And the fact that the materials were military grade and built to withstand just about anything really sold me. Unfortunately, prolonged wear hurt my right ear. I returned them a few days later and tried the Beats Fit Pro. I thought that the wings would provide stabilization and comfort. I was wrong. I didn't even get a chance to really try them out. My ears were in agonizing pain due to the rigidity of the wings. I returned them the same day I bought them. I had high hopes for Sennheiser, and though they sounded amazing, they hurt in the same way that Jabra did. Cue Bose to come in. The thing that set them apart from the competition were the comfort wings. They come in three different sizes. I tried using the medium wings first, but prolonged use still caused pain in just my right ear, even though my left was fine. The small wings though fit perfectly in both, and have not created any issues of discomfort or pain. They're actually on par comfort wise with the Sony earbuds I got almost 4 years ago. Now, the sound was night and day to anything I have ever tried before. The sheer depth of everything was immaculate, and with the app you can adjust the different tones accordingly. But the features that won out was the noise cancelling "quiet" mode, the sound heightening "immersion" mode, and the all around "aware" mode. These are the best noise cancelling earbuds I have ever experienced with the quiet mode. The immersion mode let's you listen to music in all levels around you as if you're sitting in the middle of an orchestra. The aware mode transfers sound from the outside to you as if you aren't wearing headphones at all. All three modes are miles above the other competing products I have bought. But the Aware mode is absolutely amazing as any other version of this sounds Tinny or Electronic. This was the first time I have ever forgotten I was even wearing headphones. The music may not have been playing, but the background noise was so clear that I just didn't need to take the headphones out and put them away. This actually made it easy to listen to music at a low volume and still be able to keep up with concentrating on conversations or work place activities and lectures. The case uses the USB C charging cable, and you get a full charge if it's completely dead in about 2 hours. That being said, I probably get about 6 to 8 hours with consecutive use of the earbuds on a single charge. With the charging case, I can probably go 20 to 25 hours without needing to recharge. But what I love is that not only will the earbuds audibly tell you when they are low after they've been sitting in the case, the case itself has a light indicator to tell you when the charging battery is drained. Overall, is this worth $300? Considering it blew every other $200 competitor, including my original earbuds out of the water (which I paid $250 for when they were released near 4 years ago), I would say that TO ME, they are worth the money. I'm not comparing them to current Sonys on the market, nor have I ever tried the Quiet Comfort 2s. If you feel that it isn't big enough of a jump, then cool. But to me, comparing them to all of the earbuds that caused me pain, I do feel like this is a case of "Getting Your Money's Worth." I sincerely like these, and I am happy I spent the money for the sake of impressive comfort and impressive sound quality. 11/14/2023

To put it up front, the only reason I'm not putting this at 5 stars is the lack of wireless charging and the size of this case. I have had the Galaxy Buds 2 Pro for the last 2 years, and I genuinely felt disdain towards them from very early on. I could never find a good ear fit, I bought several replacement ear buds, I did anything and everything I could. I got into running last summer and they'd stop detecting my ears, feel like they were falling out, and I constantly felt like they were not good fits for my ears. On a whim I decided to try these Bose QC Ultra buds, and it's night and day. The shape of these ear buds are definitely what my ears needed and they fit incredibly well. The little wings help them with reinforcement in my ears, and they just feel so much more natural. I also always struggled with the Buds 2 Pro's smaller size, where constantly having to adjust them within my ear would set off touch controls. Having a clear, distinct section of the ear buds that are meant to be touched is a welcome change to me in these Bose buds, and in general they're much easier to handle within my ears. Sound quality initially felt about on par with the Buds 2 Pro, but having listened to same sections of songs back to back, the Bose QC Ultra definitely are a step above. If the Buds 2 Pro were an 8/10 sound, I would put these at 9/10. Not a huge leap, but still a noticeable improvement in quality. The bass is strong (if you want), EQ is fully customizable with the low/mid/high ranges, and the volume is plenty loud for me. The battery life also has not been a huge issue for me yet. I've only had them a few days, but I've still used them for extended periods and still had plenty of battery life left. This may change as time goes on, but we'll see for that. Regarding the negatives, the lack of wireless charging is strange in this day and age. I also don't like how much larger this case is for charging, it's about 50% larger than the Buds 2 Pro case, which also supports full wireless charging. With such an increase in size and less features, it's strange to me. It's harder to carry these into the gym, where my Buds 2 Pro case fit neatly within my glasses case. It's not a huge change, but enough that my consolidated routine of keeping everything I needed in one section is a little more difficult now. Touch controls are also a little strange to get used to. You can stroke a finger from top to bottom of the touch section to lower volume, but it's such a small area that I typically end up just pausing the song I'm listening to. Play/Pause, next song, and previous song work great so far (Single Tap, Double Tap, Triple Tap respectively). I also wish there was a way to turn off the voice prompts for everything. For example, holding down my right bud turns on "Quiet" mode, which takes about 1-2 seconds of holding to activate. When it does activate, it lowers the volume on what you're listening for about a second while the voice says "Quiet", then brings the volume back up. I personally would prefer a simple audio queue to let me know it's activated and not interrupt my music. I also wish they could connect to multiple devices at once (like my Bose N700 do), but I knew that prior to purchasing and can't ding it for that. Overall the headphones are great with a few smaller issues I wish could be resolved. They're simple to sync up to any device, have great audio quality, fit my ears well at least, and feel like quality headphones. No issues with desync as others have mentioned (using S22 Ultra, also tried on Sony X85K TV with no issues).

Extremely disappointing. First the sound quality and noise cancellation is the best, Amazing, no other ear buds ive ever owned come close. Why 2 stars? Because they didnt last a year... and i had 2 pairs. The first pair, failed around the 6 month mark my first pair started getting random loud static in the left earbud, i cleaned and checked them and saw nothing that i could fix. they would randomly disconnect or reset with a loud painful pop as well. At first i thought maybe because the batteries where low. But low or fully charged i kept getting static. I made use of the warranty, Bose has excellent Customer service, but, they shipped me a refurbished pair and i had to mail in mine. Which was also disappointing, you cant send me a NEW pair?? These were $300 dollars! The second refurbished pair.... made it til a few days ago 8/26/26...and they have exact same issue Random loud static that cuts in, at one point they poped fizzeled and the sound went back to normal and then a day later random loud static again but thid time its not going away I did not have 2 bluetooth devices connected, i did reset them, and there was no "interference" because there was no one around each time, i was alone. This has to be a hardware or software problem. I tried updating the fiemware but they were up to date. Again these are $300 dollars. For 2 different pairs to die before the 1 year mark is a joke, now im out of warranty but im not getting another pair cause they are likely going to have the same problem. their quality has severely declined. I have cheap chinese headphones that have lasted 3 years with zero issues. I expect a heck of a lot better from BOSE!!!

I'm sharing the difference between the Bose sports buds and these QC Ultra. Which do I prefer? I'm still on the fence. It's the same as android vs iohone. They both have cons and pros. So what's my experience of wearing Bose earbuds? I wear the buds nearly everyday. In fact, I wear them 6-10 hours all day, at least 5 days a week. I am a highly active person. A fitness instructor, farmer's wife, country farm girl who cans and freezes all her garden produce and cares for the 6 acre yard, I have my buds in nearly everyday, all day long. Pros to QC Ultra: The sound is INCREDIBLE! The 3 different modes are crazy good! Perfect for whatever atmosphere you desire! Can't hear the LOUD white noise of the inside of aircraft, can't hear the mower when mowing the yard, can't hear water running when washing dishes. Turn in immersion and you hear everything perfectly 👌 Compared to Bose Sports buds, the buds I bought new twice, new in 2017 (lost this pair) and 2019 (didn't hold a charge more than 10 mins in mid 2023), were not as loud, clear or had the 3 different listening modes. They may have improved in all these areas. Cons to QC Ultra: The buds won't stay in my ears if I move around much. Examples would be 1. outside getting up, kneeling down, wiping sweat off of forehead while gardening, 2. the natural vibrations while mowing, 3. while singing along with the music talking and 4. Talking on the phone to someone since the jaw is moving the buds slightly, causing them to loosen and eventually fall out. Second: if you have long hair, wear hoodies or have your hands/arms moving by your head, you will activate the buds to perform a command. Mine will switch songs, change listening modes or end a social media app. Even my wet hair will trigger the mode changes. Blow drying my hair will change the modes. But when I tap it purposefully to pauce the music or change the listening mode, it doesn't consistently respond to the touch of my finger. This gets alittle frustrating when it appears the buds are so sensitive to touch but my own finger touching it with purpose doesn't consistently produce the same results. 3. These buds don't have a push button. They are only activated if they malfunction (stop responding in a way that you desire) by reinserting them into their case. This is aggrivating when I'm mowing or in the garden. Either I have to go get the case to reset them or carry the case with me wherever I go around my house and outside property. Ugh!! I wish they had a reset button like the Bose Sports. I could turn them on/off and reset, and even engage them to switch the BT device I wanted them to switch to. *So my review is meant to only serve as a tool to help you choose which you think would work best for you! If you need excellent music quality and clear crisp sounding videos, these are for you! The sound quality blows Galaxy buds & apple buds and away in my opinion. The only sound quality I've ever heard was Beats padded headphones. I'm not talking loud and blary or hearing the 5 string quartet crisp. I'm talking about hearing every instrument with perfect ease, easy to allowing your own mind switch and focus in on the the sax, to the drums, to the lead vocals, to the bass guitar kind of listening. A perfect blend of separate sounds. It's crazy! You can enjoy loud music from the sounds of the amazing Trans-Siberian Orchestra concert to a hard, bass-thumpin' NF or Aerosmith song. Anyone can listen to a band on a lesser quality set of buds with less instruments and hear the different sounds well. These Bose QC Ultra buds allow you to experience the beautiful chaos inside a "loud" concert and thoroughly enjoy each individual piece that creates the experiencial masterpiece! If you just need good music quality and know that the little quirks of the buds falling out and the sensitively of the buds will push you over the edge everyday, then I would recommend the sports buds. I honestly am not sure which I would choose if I bought another pair. I hope the sports buds have this same music quality. If so, I'd get them. If the sports buds don't have the music quality, well, I honestly don't know. I guess I'll tell you which I decide upon then, in another 3 years if these quit holding a charge (or God-forbid that I lose them).

These have a strong noise-canceling effect but the quality of sound is inferior to the QC II. I have 2 pairs of these (so it’s not like I got a bad one, both the Ultras perform the same). When I have to use my Ultras, the sounds is not as sharp, more blurry, and I have to turn up the volume compared to QC IIs in order to discern audiobooks and phone calls. I have multiple pairs of QC IIs. I have a medical condition that is greatly improved by the noise-canceling effect of headphones & wear at least one nearly all day on my more severely affected ear. The QC II are far superior. I have been using these since August. Because they are so inferior, I bought another set of QCII in October. I have been an early adopter of the very first attempts at noise-canceling headphones in the 90s. Now I use noise-canceling headphones upon recommendation of my doctor as it turns out I have an inner ear condition called superior semi-circular canal dehiscence, or third window syndrome, so these somehow improve my balance. I give them 3 stars as for me they are far superior to Apple AirPods. My AirPods fall out of my ears if I bend over, no matter what size silicone thingies I put on them. Apple products stick out so far they catch on things and fall out all the time. And they don’t noise-cancel as well. Like the QC II, they are comfortable, I can wear them all day, they recharge quickly from the case and it doesn’t seem like I have to charge the case too often, I can wear them on the treadmill, walking the dog, shake my head vigorously and they stay in. My ear canals don’t hurt even if I wear them all day. Would be nice if there were a way the case could “find” the earphone of it falls out. I have dropped my case with earbuds in it, then the earbuds fall out and kind of explode into a room, flying on different directions, or taken out one earbud to have a conversation with someone and dropped it, and haven’t been able to find the earbud. Of the earbud could make some kind of noise to help you locate it, that would have saved me literally hundreds of dollars, but that’s also a problem due to my balance issue which makes me clumsier than the average person. On the other hand, all the times I’ve dropped them with a big crash, neither the functionality of the case nor the earbuds was affected. Compared to Apple, sometimes I lose connectivity to the headphones for no clear reason I can tell and it can be awkward to re-establish connection and somewhat frustrating, have to turn phone on and off etc slightly annoying. I connected them to my work computer then they wouldn’t work with my phone until I reset. It wasn’t easy to reset when I was on the go, I had to do it on a weekend.

These are the first Bose product I've really liked...for context I'm not into reference , I enjoy gentle colour and soundstage. I love space and natural bass. Bose sound sport were disappointing, and Yamaha, Apple, Samsung earbuds all sounded small and narrow. Not these. Just in stereo mode these recreate well separated clear instrumentation across electronica, classic, EDM , jazz and rock...detailed and rich bass, pleasant minds and detailed highs that only get slightly shouty at full volumes... but far out the immersive mode.....what kind of technowizardry is this? The separation starts to stray into the territory you get with decent DACs. Whilst obviously not 100% accurate it's so dam nice and moreish everything from Max Braiman to Liz Frazer to Wagner to System of a Down were injected with a space and size and shine and I smiled so hard it squeezed them out of my ears..one tip adjustment later and a grin couldn't displace them. In all honesty if you want peak quality wirelessly you need over ears ( Shure are the most musical to me) BUT if you want small form discretion and convenience ( plus the best noise cancelling period) I heartily recommend these. Convenience wise the app downloaded easily after they earbuds found my phone and linked up effortlessly. I'm no Bose fanboy, but these are massively worth the extra expense. You get what you pay for with these... Consider me amazed.

The Bose QuietComfort Ultra Wireless Noise‑Cancelling Bluetooth Earbuds deliver an outstanding listening experience, exactly what you’d expect from a flagship Bose product. The noise cancellation is powerful and immersive, making music, calls, and podcasts feel incredibly clear even in busy environments. The sound profile is rich, balanced, and detailed, with deep bass that doesn’t overpower the mids or highs. Comfort is another major win. The earbuds sit securely without causing pressure, making them ideal for long listening sessions, commuting, or travel. Connectivity is seamless, and the build quality feels premium and durable. If you’re looking for earbuds that combine luxury comfort, superb noise cancellation, and exceptional sound quality, the Bose QuietComfort Ultra is an excellent choice — a true upgrade for anyone who values high‑end audio.

Excellent noise cancelling earbuds. It come s with different sizes of earpiece to make sure you can find one that is working/comfortable for you. I used to have a different brand earbuds but it kept falling out while I was doing my morning walk. Bose earbuds stayed there the whole way. Sound is great too.

Estoy encantadísima con estos cascos. Funcionan de maravilla: se conectan al instante tanto al ordenador como al móvil, incluso a ambos dispositivos al mismo tiempo, y nunca me han dado problemas de conectividad. Lo que más me sorprende es lo bien que aíslan del ruido para ser unos auriculares tan pequeños tipo in-ear. En la oficina me permiten concentrarme sin distracciones y, si lo prefiero, también puedo activar el modo Awareness para escuchar lo que ocurre a mi alrededor, algo muy útil en el tren o en la calle. Incluso en ocasiones los uso sin música, solo con el modo silencioso, y me basta para reducir el ruido del entorno. Una auténtica pasada. Además la sujeción es súper buena, podría salir a correr con ellos y no se me caerían. Vienen con diferentes tamaños para que te pongas el k mejor se adapte a tu oreja. A mi se me caen siempre los auriculares de este tipo pero estos no pk lleban una cosita que no recuerdo como se llama que da un agarre extra y es la clave. Por fin un auricular de este tipo que no se me cae. La batería dura mucho. La app a mi me parece perfecta. Es sencilla pero para qué quiero más. No me gusta que sean complicadas con mil funciones que no voy a usar. La app es intuitiva y fácil de usar y tiene todo lo que necesito. El audio es bueno pero no soy experta y me dicen que se me oye bien por el micro cuando hago reuniones. Yo les dos un 10 de 10.
