I think these earbuds are great, great sound quality, great fit and very good noise cancelation. I was just disappointed that I could not trade in my old pair to get these. I am a loyal Bose fan, have been for years, that's why I was so disappointed they would not except trade ins for this product.

I bought this product about 2 weeks ago. My first impression was that the noise cancellation was absolutely amazing. The fit was not right at first but then using the different tips and ear fittings it got perfect. Good product, great company what more could you want.

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!

I got them around 3 weeks ago and it has been an excellent purchase, the noise canceling and the fitting are amazing, allowing me to either watch a movie with my phone or TV to go out for a run without any issues while running as the fitting and comfortably feeling they provide goes above and beyond the expected and the competitors out there.

[This review was collected as part of a promotion.] I bought in November but within 2 months one earbud stopped working. Support was excellent and they are sending me a new pair. Fitting in ear is only ok i find when i chew or talk they tend to fall out.

I've had these about a month now and for me they are great. Very comfortable, very good sound, pretty easy to use and setup. App could be better with less duplication and a bit more intuitiveness (that's me anyway). There are areas's that could be better are the cable: too short and should have been USB-C on both ends. I also have had a few times where only on bud worked or linked up and had to put back in the case and take out again to fix on the spot. The case is also a bit big for sure. I'd think that easily could have been smaller. More volume would be nice.

I have been a Bose wired earbud user for many, many years, as I believed that they would provide the best sound quality for my music. Well the Bose QuietComfort Earbuds definitely changed my opinion, especially for listening to music. The sound they produce is fantastic and far superior to my Bose wired earbuds (and it is nice to finally not have to worry about inadvertently catching the wires on something!). I love most genres of music and they all sound fantastic. I am particularly impressed with the full, high quality sound and deep bass for my favorite genre, progressive rock. The noise canceling feature makes listening to music substantially better by drowning out surrounding noises (but it is nice to have the ability to "turn off" the noise canceling feature when the situation merits). I appreciate the ability to adjust the fit based on your inside ear size which makes them also very comfortable to wear (I had them on for over 3 hours the other day and no discomfort at all). They are also not too clumsy looking when wearing. For the sound they produce I would have expected something a little more bulky. The touch controls on the earbuds themselves took a little getting used to, and were frustrating at first. This is in part due to the wide variety of adjustments and options available on the earbuds. Watching the "How-To" videos that Bose provides definitely helped. I also like the convenience to use voice controls to adjust volume and advance tracks. The charging case is nice, and I particularly like the way the earbuds fit snuggly and are held in place with tiny magnets (ensuring they are in the proper position for charging). Speaking of charging, I last used them for about 7 hours before I felt the need to recharge the earbuds. The Bose QC Earbuds app works great too and is necessary to take full advantage of the earbuds (e.g., the EQ feature). Just one note of warning; the app only works for iOS 15 or above. So us old-timers with an iPod Touch that can't accommodate iOS 15 and above can't install and use the app solely on the iPod (but you can still concurrently use the app on your iPhone). If you particularly enjoy listening to all types of music, I highly recommend a pair of the Bose QC Earbuds. You won't be disappointed. The sound is just simply fantastic and pure Bose!

The sound quality and battery life are wonderful! However, the earbuds are very sensitive. There is an out-of-ear auto-pause feature that cannot be turned off. Unfortunately, when I bend down or tilt my head, the earbuds sense this as out-of-ear and automatically pause. Additionally, the touch controls are quite sensitive. Even the touch of my hair often causes the earbuds to pause.

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.

Being a big fan of Bose quality, I am disappointed by the poor quality of the craftmanship of these earbuds. You can tell that the physical quality is inferior to any of Bose earbud offerings. I'd rather Bose focus on quality than make an inferior product to target a budget market. Only one ear works with any degree of consistency. The touch of the earbuds is usually unresponsive. The rubber bands do not stay in place and make for an ill fit. The earbuds also struggle to fit in the grooves of its case. I prefer the wider horizontal design. The bass option does not increase bass. The noise cancellation is good, and I like the awareness option to tune me in and out as necessary. But I would not recommend this "Bose budget buy" after being an owner of the Bose QC earbuds from 2020. I will be returning the earbuds. Yes, I have tried troubleshooting but the quality is poor and it requires daily troubleshoots.
