I bought these a month ago, and I'm so disappointed. I got them to replace some that I bought in 2020 that finally crapped out. On the plus side, the fit is nice, and the noise cancelling works really well (just what I expected from my last pair). What I hate about them is that the voice that comes on and give you alerts like, "Battery 100%" is really loud, which is problematic for 2 reasons: 1. it just hurts my ears. 2. I use these to sleep to drown out my husbands snoring and the alerts come on when I am asleep and wake me up. Now, let's talk about why that is. It's because these darn things stop working after about 20 minutes. From my research I gather that this is related to not moving. So, if it takes me longer than 20 minutes to fall asleep, they go off before I would like. But, when I AM asleep, they randomly come on with the loud voice to let me know that the battery is 100%. I contacted customer support and was told that there is no way to adjust the volume of the alerts since it's a "default setting." I absolutely hate these things, and I'm planning to return them. I hope I can do that.

I had an ipod and ipod pro and both broke after 2 plus years of using which is why I needed to buy a new one for my workouts and runs. Though I have only used this for a month, I can’t really tell its durability but the sound and acoustics are by far much better. They are much more bulkier but fit much better on my ears that I rarely make adjustments when I am moving during running. They are just too sensitive that when I need to adjust one of them, it would automatically pick it up as a tap and does a function e.g restart, stop or next track.. But otherwise I am happy with the purchase

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.

Received the quietcomfort earbuds 2 weeks ago. These have been the best earbuds that I have ever owned. I used to use Apple AirPods which these don’t even compare. Comfort is a lot better and doesn’t hurt my ears after a hour of use. Noise cancellation is good with quality and providing a HD experience. However, I still can hear my surroundings slightly for safety which is something I value. At first, the earbuds took sometime to figure out to pause when I took off the earbuds but that improved after a couple uses. I wish that it was easier to take the earbuds off and play something on my phone speaker without needing to place the earbuds in the case to disconnect the Bluetooth temporarily. For example: if I want to play a short video to a friend, I wish I could just take off the earbuds and place in my hand temporarily versus needing to place them in the case to disconnect. If I don’t place in the case, it will still play through the earbuds. I also cannot believe the battery life. After 2 weeks, I am still at 100% and I use it on and off throughout the day. Very impressive!

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.

Great head phones but I've noticed some issues with connecting with multiple devices. I've also experienced some issues with high pitch noise/notes and the head phones cutting out. The earbuds fit well and the color is great. The box is easy to charge and sleek.

[This review was collected as part of a promotion.] I bought these QuietComfort Earbuds a few weeks ago and I am really pleased with the sound. Spoken words that come from the webinars I listen to are crisp and the music range from highs to lows is great. I like the new case design and the ease of pairing my buds with my desktop, iPhone, and car.

I went from the Sony wf1000xm4 series earbuds to these Bose QuiteComfort. These Bose are a good bit better than the xm4 series. Note that I did really like the Sony earbuds, and I suspect the new xm5 series where they resolved some customer complaints will still make them a great pair of buds. I just wanted a change to see the difference in the brands. The good - noise cancelling is fantastic! I just flew from Atlanta to Vegas roundtrip and with music playing I could not even hear the loud plane noises. Mowing the grass, also great, I can still hear the mower just a bit but I don't have to blast the music to drown it out like I did with the Sony. The medium size ear pieces fit perfectly for me, again also a better snug fit and more comfortable than the Sony. Sound quality is what you would expect from Bose, amazing. The app that is used with this model is really good, I like the ability to set the equalizer for the sound. The bad, but not really that bad - like most have mentioned, the carrying case is a bit large and bulky but does not bother me. I don't care they stick out of my ear, also something that does not bother me. So far, that's about it, I do really like them!. Last thought, for the price compared to the quite comfort ultra, you can't go wrong. I imagine the ultra are a bit better but I doubt I would be able to tell the difference. In addition, sorry Sony, but these are cheaper than the newer xm5 model. Overall, excellent earbuds!

Product is great. Works as advertised. The documentation, packaging, and apps required are terrible. I have downloaded two different apps. I downloaded the Bose app and it took forever to pair with the ear buds. When it does, I click on the earbud name and it directs me to download another app. I downloaded the other app and it takes another eternity to pair and often won't work at all. Really poor experience with the apps.

[This review was collected as part of a promotion.] I have had those for a month and they have great sound. I have a little trouble with the fit in my ear. I switched to the smallest ear canal foam and it is a better fit in the canal now, but still is coming loose in the ear.
