I purchased this product with high expectations. They are great when it comes to noise cancellation. I have yet to see what else they can do, but they don't stay in my ears. I have adjusted and switched the attachments that came with it. It seems that my ears are to small for the bud to stay within my ear. As soon as I bend over or am constantly moving they slip or fall out of my ear. With the work that I do I can't afford for them to do that. I'll have to try again and look for a product that fit small ears.

[This review was collected as part of a promotion.] I bought 2 sets of these because excellent workout partner. One tap to pause is helpful when on elliptical. Noise reduction not good as more expensive models but could be helpful when running outside. I believe a burn in is necessary after some they sound much better. The noise reduction is better also. I use them everyday now. They seem secure in my ears haven't fallen out yet.

I looked at the Bose QC earbuds several times and just kept passing them by, but they went on sale for $129 and I couldn’t resist. So glad I got them. They are awesome. The sound quality is as good as the best I’ve heard, the noise cancellation is superb, way better than my Bose QC2 over the ear headphones. Couldn’t be happier.

They fit nicely, sounds great although I did experience drop/lag watching movies. Easy to connect to all devices. Sometimes one bud that would not have sound while the other was fine. I had to Pair with TV more often than with Air Pods. Would rather wear Bose for sound and comfort than Air Pods.

[This review was collected as part of a promotion.] I bought my quiet comfort earbuds like the last two months so far it has not disappoint me at all , its so light in the ears , sounds sooo good and crisp ,the battery life takes forever to run out . Its so dependable . I love it ! .

I bought these to replace my Apple AirPods as I’ve had two sets now and eventually I get to where ppl can’t hear me talk very well. I’ve trouble shooted with Apple and it didn’t help I figured it was time to try something different. So far these have worked really well. They fit nicely in the ear just the way they arrived although there are other pieces to change out sizes. Sound quality is nice and you can make the sounds work for you with an equalizer and a lot of other features in the Bose app. Bought these pink as it’s my fave color and they are a nice soft pink. Very pleased with purchase.

These earbuds are too Big & they hurt my ears! Was hoping to replace my wired Bose, sad to say They Did Not replace them I use they more. Bought two pair years ago and just shared a pair with my husband he said they sound the best he has used. I had called and asked about a smaller ear bud, was told I would get a kit to fix them But ten days and No Kit!! till then NO More Stars

[This review was collected as part of a promotion.] Bought this a month ago, and only have good things to say, except for one small issue. Pros: 1. The fit in my ear is OUTSTANDING. The way these are designed to use different parts of your ear for support is brilliant. They fit snugly without moving, they don't fall out while running/in the gym, and they don't press too tightly on my inner ear (unlike some "Pro" level in-ear earbuds). 2. The noise cancellation is excellent, much much better than air pods (even the pro version). 3. The 'Aware' mode is not the best transparency mode out there, but is more than enough for normal use. 4. The sound quality is more than good enough, you're not going to get much better out of earbuds. Cons: 1. These pick up a fair bit of wind noise. When running, I usually have to switch off the noise cancellation, but this is OK since the noise isolation is still pretty good.

I bought these earbuds for the extended battery life and the reviews I saw online, I love Bose products and I'm a loyal customer. I also have the QC II earbuds and I have to say the sound and NC is superior on the QC II, but the fit is better on the new QC earbuds. The QC earbuds still have amazing sound and good NC. A few things I've been having issues with is connectivity, I have issues with the earbuds connecting to my phone or devices at times and the case is not as simple and easy to open. Overall, they are a good pair of earbuds and value for the price.

This is just one of many Bose products that I own and it’s amazing, just like the rest. I have multiple Bose aviation headsets. I have Bose QC headsets. I also have Bose in my truck and I own a couple of Bose portable speakers. I cannot stress how awesome of a product Bose makes.
