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 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 don't work in a peaceful environment with timid people, who are respectful of each other and know how to shut up. No. I work in a warehouse. Not a good warehouse. A small warehouse. With 30 people in a single room. People who literally SCREAM along with the music playing over the speakers. People who think being the most annoying person possible is funny. What's worse. It's 10 hour shifts. I've had enough. I decided, time for noise canceling headphones!! This review is for someone in the same position as me. That NEEDS, DESPERATELY, some way to shut down the noise around them. After much debate, I decided between two choices. The Jlab Epic Lab True Edition (200 USD) and the new Bose Quiet Comfort Ultra headphones. (250 USD) I went with these two because 1) I was very interested how jlabs new signature headphones would compare to the 20$ version they offer. I wondered how much better it could be for 200$, also I was interested in the Knowles corporation equalizer preset. Big audio company. 2) Bose is the leader of ANC headphones. I've never had a pair so I had to see what the fuss was about. I got both of these on Amazon knowing I can return the worst pair within 30 days. After using these, I want to apologize to my past self for not doing this sooner. I have broken them in over the past week at work, and it's the only time I have been there I haven't wanted to walk out within hours or gotten crazy depressed. I realized. I actually like my job. Let's start with jlab I'm going to get this out of the way. If you relate to my situation at all. These are not the headphones for you. IF you have a good life. A good job. One without people literally screaming in your ear 10 hours. Please get these. The audio quality on these are amazing. I was shocked. I honestly teared up when putting my favorite song on for first time. I heard parts of that song I have NEVER heard. You will experience this. The Knowles setting is life changing. These are a daily driver for sure. I am impressed. Comfortable and very water resistant. The active noise canceling is actually pretty good. I could barely hear my husband with music on. But my situation....multiple...people...yelling, in union, to Taylor swift. The jlabs can not handle it lol. It does get muffled...a bit. Which honestly, is loads better than just white knuckling it. But if you are looking for strictly ANC, don't get these at 200$. Are they worth 200$ on sound quality alone. Gods yes. Are they worth that...to ME. Ehh.. Bose. Honestly I was not expecting to like these as much. I heard a lot of things about loss of connectivity plus not being water resistant. In my warehouse. I do get water on my hands sometimes so I did not have high hopes. But let me tell you. The second I put these on at work, before the music played it did the ANC switch and I was the happiest I have been in months. It instantly took out the warehouse music, the machines, the fans, the background noises and 80% of the talking. I felt like I could breathe for once. The overstimulation gone like *snaps*. Then the music started playing. I was watching my coworkers mouths and I broke out in a huge grin that lasted minutes. I could see them talk, but hear them talk I could not. This is the first week in months where I didn't get depressed after about 30 minutes of that. So the ANC is legendary. The sound...is not. I keep looking at my jlabs like... ??? How do they sound so much better?! I think the bose default settings out of box is just too treble heavy. I used the app to set mine +9, +4, -2. That is the closest I can get it to sound like jlabs but they still don't. Why?! I don't know why. They still do sound good. Like a 8/10. That plus not hearing my coworkers discuss if lobsters have souls, makes this purchase on sale at $250 a steal for me. I'm going to be returning the Jlabs and looking for a future sale. I would like to have them in my collection for when I just need some good headbanging. Both headphones are great, but get the one you need for the life you live. Take care!

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.

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 owned some traditional Bose noise canceling headphones for years that I've used extensively for travel, mowing the lawn, etcetera. They're great! I was looking for something I could use every day, and because of my experience with the brand I purchased Bose QC Ultra Earbuds. Starting with the unboxing - Bose did a nice job with packaging, but you'd expect that in this price range. The earbud charger case is a nice shape and size, but it lacks wireless charging. This is disappointing for these high-end earbuds. The next thing I tried was removing the earbuds from the case. This is where I began to get annoyed. Perhaps there’s a trick I’m not aware of but getting the earbuds out of the case is much more difficult than it should be! The Earbuds themselves are very nice. After trying them for fit, I realized I needed to go to the larger Eartips and Stability Bands. Bose did a nice job in their manual stepping you through checking the fit and the replacement of these pieces. Once I replaced them, the earbuds are not falling out. This is especially important to me as these will mostly be used while riding my bicycle. I had already loaded the app and the earbuds connected without any fiddling on my part which was nice. I put on some of my favorite tunes and began testing the different settings; Noise Cancellation, Immersive Audio and Listening Modes. All were impressive, and each will have a place depending on the situation. Very nice! I realize this is a review of the earbuds, but the app is an important tool while using them. For example, there’s the ability to customize different combinations of the settings and setting them as favorites for quicker access. There’s also the ability to modify the default touch settings. I haven’t done this yet because I plan on living with the defaults for a while to see what might be lacking for me. Generally the app and connection is rock solid, but there was an instance where the earbuds kept loosing connection. An uninstall and reinstall of the app seemed to cure this. All in all I am happy with this purchase. Time will tell if the quality matches my original Bose headphones, but I am optomistic on that front. The only negatives I've found to date are the design of the case when extracting the earbuds, and the fact that the case doesn't include wireless charging. Hope this helped!

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

I work in construction. Came from using Shokz OpenComm (the one with the microphone). I bought this so that I can make calls, to some extent of some noise isolation, listen to music / podcast and making calls traveling between job sites. Noise Cancelation: Its sounds great when you are in a quiet room. At the job site, its practically useless. It doesn't cancel out any heavy equipment noise. There is a bit of the noise isolation effect from how the seals are covering the ear and the ear canal. Generator noise: it can cancel out a fair share Jack hammer noise : meh. negligible cancelation. Circular saw noise : the earbuds cancels out some of the saw noise but create their own sharp shrieking noise counter to the saw noise Concrete saw noise : it can cancel out a fair share of the noise while the machine is cutting but it makes its own shrieking sounds. Driving a van : it does cancel out a lot of the ambient noise that you get while driving a van on the freeway. Swim meet at a Natatorium : It was really nice to be able to cancel out 85% of the crowd noise but of course, it was a struggle to communicate with people around you. Call quality: I have yet to find an environment where people would say that they could hear me well. The first pair was returned within a week. Volume while listening to music I would use about 30% of max volume but could go all the way up (to where it was painful). On calls, it would be stuck at 20% of max volume. I had to turn in my pair and wait 45 days for the new pair to arrive. Mic quality : comments from people I am on a call with : "sounds like you are in a tunnel far far away", "there is so much echo", " you sound muffled". Many a times I would just have to remove the earbuds, put them back in the case and use the phone regularly so that the other party could hear me without distortion. Bluetooth Connectivity : I have it paired with my Samsung S24 Ultra. It has stayed connected for the most part. For the few times in which it didnt connect well, I have just put it back in the case and took it back out. Ease of use : the most challenging part is trying to get it out of the case without dropping them. It has a pretty decent magnet to keep it in the case and somewhat limited grip area to get it out. It took a few tries at the start to learn how to put them on but after that, its was easy. Bose has its own app to control and personalize certain aspects of the user preferences but that is a few menus in to the app in order to change anything. They need a widget in which an user can have some quick buttons or controls to shift from modes or to fine tune certain uses. As a general comparison between the Shokz Opencomm with ear plug (hearing protection) combination vs Bose Quietcomfort Ultra Earbuds for my general work, over all calls, general functionality in use for noisy work environments : I would go with the Shokz Opencomm all day. For the few moments, in which the noise cancelation works and you dont need to communicate with anyone : just sit there and listen to your music/ watch your show : the Bose Quietcomfort Ultra has a better sounds quality and its an enjoyable product. For the price, I was expecting a whole lot more out of the Bose in quality of noise cancelation, quality of the mic for phone calls, ease of use. In general, just disappointing for a Bose. For a product at $300 range, it underperformed for what I needed.

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.

After short use it started disconnecting in left or both earbuds (iPhone 14 Pro; my other earphones work great with it). Factory reset did not help or just for a short time:( I have tried 3 (!) of the earbuds and badly wanted them to work properly, because ANC and sound are great and the buds are smaller then the previous version (non-Ultra), but every one had the same problems. I love Bose, but these are terrible. Btw Amazon Customer Service is very good - huge props.

Premier achat : des bourdonnements très forts dans les deux écouteurs après 3 semaines d'utilisation Second achat : tout va bien à part quelques lenteurs de connexion. Après 2 mois une catastrophe pour le connecter à nouveau. Le pire produit Bose que j'ai acheté.

Wirklich guter Sound und einstellbar. Bei dem Preis aber auch ein Muß. Habe parallel die Apple Air Pods Pro getestet. Meine Frau und ich waren der gleichen Meinung die Böse sind klanglich eine ganze Ecke besser

Ecouteurs géniaux avec plusieurs modes d'écoute personnalisable selon nos préférence. La tenue de l'oreille est top et l'écouteur ne se sens pas quand on le met contrairement à d'autre intra-auriculaires.
