I liked the sound produced and nouse canceling, but I could not tolerate the fact they disconnect every 10 seconds or so during exercise (always the left earbud). I deleted the app & bluetooth, retried several times, but in the end I had to return. Do not recommend

[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.

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.

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.

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.

The sound quality is exceptional. My experience thus far has been more functional. The sound drops out for no apparent reason. I have trouble keeping them in my ears. I have followed the advice from the videos to change the ear tips and stability bands to find the best fit. To be fair, I have one ear that is not like the other so the earbud does not stay put.

[This review was collected as part of a promotion.] In regards to the Bose headphones, I found my experience rather superb. The design provides a comfortable and sturdy earpiece that won’t fall out the ear. Along with the design, the color adds that pop of unique and personal touch.

I have rarely been as disappointed in a purchase. I already have a pair of older Quiet Comfort that I am extremely pleased with: fit, performance, pairing, app, sound and noise cancelling These are the opposite in all those categories. The reviews said these were as good as the current Ultras. Not true for me. The price was right at the upper end of my price point. I should've passed. Also- why the hell are these made with the serial number in a position it's impossible for humans to read?

I love the quality of sound that they provide. The quiet mode is the best I have tried. The only thing that I do not like is that the right one tends to fall out while mowing the lawn or doing any activity other than working at my desk. It would be awesome if Bose would make an over the ear retention style adapter for these. Others just don't seem to have the sound quality. Not a specific Bose issue but this style of earbuds does not provide ambient noise cancellation for the person on the other end of a phone call. It would be real cool if they could be equal to the ambient noise control of the Blue Parrot headsets.

Bought these based on prior experience with 25 years of other Bose products, like the feel, sound of the buds Bud would have liked to have at least a quick guide to get the buds up and working with my Bluetooth devices. Case in point, I did not know you had to load the Bose app to control the functions, such as volume up volume down on each of the earbuds and assumed right earbud was volume up, and left earbud was volume down. Had to go onto this out. Bose needs to do a better job and providing self instruction videos on their website for new and old products alike.
