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

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 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.

The good:1. With a good seal noise cancellation cuts out most low frequency sounds.2. The sound quality is premium.3. They don't chafe the inner ear no matter how long I wear them.The bad:1. The USB charging port started feeling mushy and wiggling around after about a month of use. I had to fiddle around with the position of the charging cable to get it to charge. Not good. For Bose to correct this, they said I'd have mail me new ones which would be about a month turn around. I bought the wireless charging silicone case cover instead (wireless charging should have been included at this price point as it is with competitors) and found a design terrible in almost every respect. $50 sticky rubber thing that every bit of lent and grass and dirt adheres too and the top just falls off the lid and flops around. Just another shameless money grab by a once respected company.2. I get a good seal but no matter what I do the buds just start working themselves out of my ears while doing anything but sitting perfectly still. I had to buy the extended fit kit which again should be included and not extra. Again another shameless money grab for a couple of pieces of silicone and it still doesn't fit right. When a bud works it's way to almost falling out, I have to carefully push it back in without touching the touch control area, but that area is so large that it accidentally pauses playback anyway. Very frustrating. I really curse Bose a lot while using them.3. The touch controls are half baked. There's a delay like the app has to wake up for it to work. When it does respond, it gets double tap wrong about 75 percent of the time misinterpreting as a single touch to pause or skips back instead of one track forward. After about 4 tries it gets it right and the track goes forward. Incredibly frustrating. You're better off just turning the touch controls off.4. Sometimes the left bud won't turn on so I have to put them back in the charging case and try again. Happens about once out of 5 times. Sometimes I have to do this repeatedly to get them to work.5. Noticed the outer silicone flange is weakly held in place and tends to fall off when removing the buds from the charging case. I usually discover this when the fit is even worse than usual.I'll use them till they wear out, but I will never buy anything from this miserable moneygrubbing company again. I've really grown to dislike Bose because of these buds. They are so buggy. I was OK with them at first. The problems seem minor as I was taken by the sound quality and really wanted to like them, but they slowly ground me down with daily petty annoyances. They'll wear you down too, friend. I wish I could get my money back. Slowly your opinion will shift as mine did and possibly like me when it's too late to return them. I hope not. Fellow traveler, it's too late for me but there's still hope for you. In the upper right hand corner of your browser is the back button. It's that arrow pointing to the left.

I extensively tested what I considered to be the top three earbuds for use with Apple products. Rated 1 (Poor) to 5 (Excellent).Bose QC UltraTreble: 4.5Mids: 4.5Bass: 5Immersive Sound: 4.5Overall Sound: 4.5+Noise Canceling: 5Bluetooth: 2.5Battery Life: 4Fit/Comfort: 4/4Controls: 4Beats Fit ProTreble: 4Mids: 4Bass: 3Immersive Sound: 3.5Overall Sound: 3.5Noise Canceling: 3.5Bluetooth: 4.5Battery Life: 4Fit/Comfort: 4/3.5Controls: 4Apple AirPods Pro2Treble: 4.5Mids: 4Bass: 2.5Immersive Sound: 4.5Overall Sound: 3.5+Noise Canceling: 3.5Bluetooth: 4.5Battery Life: 4Fit/Comfort: 3.5/4Controls: 2General impressions:The Bose were hands-down, the best sounding of any EarPods I’ve used. Highs and mids were crisp, the bass was super rich especially with enhancement through third-party equalizers such as Boom. The Bose app which is required, was not difficult to use. Immersive sound was fantastic. Noise cancellation was top in class. Bluetooth is a bit annoying, with occasional drops. The Bose two source Bluetooth set up in the app is a bit squirrelly and is better set up as a one source item.The Beats also had crisp highs and mids, however, the bass was somewhat wanting. In order to make the bass sound more punchy, the volume of the mids and highs is lessened during the hits in order to make it sound like there’s more bass than there actually is. I call this “fake bass“. The H1 chip makes it work well with Apple products and the immersive sound is good. Noise canceling is par. The ear fin does help hold them in your ear, but does get uncomfortable after a long period of use.The Apple AirPods also had crisp highs and mids, but the bass again was somewhat wanting. The AirPods had the same issue with “fake bass“. Enhancement with third-party equalizers doesn’t usually sound too good. Seems like these earbuds are meant for plug n play without any equalizer input from the user. The H2 chip sounds really nice with immersive sound. Noise cancellation was also par. Controls were very difficult to use without knocking the buds out of your ears.

Pros:I have worn these on a plane, while mowing the lawn and while standing next to a gas powered generator and they work great while blocking nearly 90-95% of the outside noise. Sound quality is superior to any ear buds I have owned. I enjoy a little more base when listening to music so using the app I was able to get the sound set to my liking. Rechargeable carrying case is light and the battery life is good, though less than others but using the full Emersion sound accounts for some of this. In my opinion it’s worth the trade off. It’s great to ditch the giant headphones on planes and still get great noise canceling and sound quality.Cons:There are conflicts when connecting with other devices. My Powerbeats ear buds would allow two connections to both my iPad and iPhone and the ear buds would switch automatically depending on which I was using. Sadly the Bose earbuds don’t do this so I am constantly having to manually connect them when switching using the Bose App. Volume control, pause and skip are touchy and I find myself pausing the music accidentally or skipping to the next song. Powerbeats uses a physical button push which feels more interactive. I started using my phone to control volume, pause or skip songs but I found once I do this, the Bose earbud controls are over ridden and stop responding to attempts to control my media. I don’t use the pause button when attempting to have a conversation I just remove them. There is no way to add the Earbuds to the “Find my Device” App on IPhone and Bose does not have this feature. I misplaced them while on Vacation and learned quickly to always but them back in the case when not using them.I would still recommend them due to their superior noise canceling and sound quality. It’s nice to be able to ditch the giant headphones on planes but I wish Bose would have fixed some of the above issues.

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.

Updated Review 7/2026:These have the best noise cancellation on the market, in my opinion. They also have the worst, buggiest, annoying software known to man.First off, the crash. A lot. When they do crash if you're lucky they just go dead in one ear then reboot. If you're unlucky they crash with a deafening POP that leaves your ears ringing.Then there are the firmware updates. The ones that install with no warning, then suddenly your earbuds are even buggier than before because their Q&A is so bad. I own two pair of these and one was bricked so hard by a firmware update the batteries would never charge properly again and I had to RMA them. Of course the replacement is "refurbished" and not even the color I originally purchased.Then there's the bonging. God, the bonging. If you dare wander out of range of your phone it bongs at you. Incessantly. It continues to bong in your ears for 2-3 minutes until it finally gives up and disconnects. Meanwhile you've gotten so annoyed at the constant bonging that you've ripped the things out of your ears.Someone at Bose must have realized this was a stupid "feature" because they tried to "Fix" it--by making the bonging two tone during the last firmware update. Now instead of BONG BONG BONG you get BONG-DING, BONG-DING, which is somehow even worse.These are such pieces of garbage I actually bought a set of Sony earbuds instead. At least their software is only moderately garbage rather than total garbage, and if they lose signal they let out a single tone then SHUT UP.Reducing rating to 2 stars, and that's only because the noise cancellation is better than Sony.These are better than my Sony WF-C700N. They're more comfortable, the noise cancelation is better, and the bass is better.They are not more than three times as expensive better, though.They also have annoying problems.1.) The left earbud likes to make low volume high pitched bleeping noises, making it had to use them as just noise cancelling earplugs. I end up having to play white noise just to drown out the annoying noise.2.) The noise floor is high. Sitting there with nothing playing not connected to anything there's a definite low level white noise. Have you ever stood outside on a frigid winter day in the woods, when there's no wind and no animal noises? It's like that. It's not unpleasant but it's there.3.) Annoying connectivity problems with my Sony XBR-85X900F. Sometimes I have to turn the TV off and back on to get audio to play, even when it shows connected.4.) Lack of LEDs to display status on the earbuds. My $35 Chinese special earbuds have these for crying out loud.5.) They smelled weird out of the packaging, almost a moldy smell. It's still there even after having used them for a month. Not fun when you're shoving them in your ears.6.) Battery life is only OK, and with some of the sound options turned on becomes pretty bad.They do a good job at drowning out the incessant train noise, barking dogs abandoned to be bored in their back yards all day, and my annoying neighbors that all cut their mufflers off during the "C".The bass is strong, especially with bass boost turned on.Overall sound quality is good, if the volume of what you're listening to is high enough to drown out the high sound floor.Honestly though, you can get 80% of the performance of these for less than a third of the price. These are only worth buying if you have money to burn. They also need firmware updates to handle the annoying glitches.

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.

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.
