Purchased these to replace (augment!) an older pair that I purchased long before bluetooth, and ear buds. They're comfortable and stay firm, and the noise cancellation remains unprecedented. Love the ability to toggle to 'aware' mode in certain settings. The available colours are a great added bonus, too.

[This review was collected as part of a promotion.] I bought these a few months back and they work great for my workouts. I like how they are cordless and noise canceling so I don’t have to hear what’s going on around me. I can just play my music at a calm level, and hear it crystal clear

9/10 The good: It's noise canceling is amazing, you can't hear a thing with it on I love music and the quality of these headphones absolutely changes my listening experience. The bad: The headphones don't really fit my head too well, it feels straight odd Sometimes it makes a sort of clicking noise out of no where when there's nothing playing And finally, if noise canceling is off then if too loud of a noise happens close to the headset, it tops out, for example, if you jingle keys near it, it sounds toatly scuffed.

[This review was collected as part of a promotion.] I couldn’t believe it until I got it myself. But I absolutely love these headphones the different modes. I love to use them to workout with. And let’s not forget about the color of them I absolutely love the color.

[This review was collected as part of a promotion.] I have had plenty of headphones including some popular brands. The Bose QuietComfort headphones are by far better than the rest. I love the easy access button for noise cancelling/aware mode. One minute you hear outside noise and with the press of a button, you hear only your music. The sound quality is also great and sounds like I am in a music studio.

[This review was collected as part of a promotion.] I purchased these headphones a few months back and the sound on them is great and the noise canceling is awesome. The only thing I think Bose should look at with these and frankly all of their headphones is some sort of speak to chat feature; just like with Sony, where when someone starts talking with you and your headphones are on when you start talking back to that individual it will pause your music and key up the ambient mics.

[This review was collected as part of a promotion.] I’ve had these for a few months now and I love them. I use them at the gym and the noise canceling works great and the sound quality is great as well. I also really like being able to adjust the sound settings like the bass and treble using the app.

Having had these for just over a month, I've noticed I love them the more I use them. They replaced a pair of Beats Studio Pro 4, which I handed down to someone not so picky about audio quality. I have my EQ flat for my audio streaming service and fine tune it with the Bose app and I have found this to be the best way to tune your Bose QC's to your ears. Aside from excellent sound quality, they are lightweights, portable, and comfortable. I wear them for my workouts at the gym, at bedtime and not once do I feel discomfort. I could not ask for anything more.

I actually have the Bose Ultra and can't believe the quality and sound of these headsets. I turned my television up as loud as I could while listening to music on my headset. AlI I could hear was beautiful quality music. The sound is unbelievable. These headsets are beyond anything I could've imagined. I'm a very happy customer!!

I would like to take it MUCH higher, as if these brand new, updated, expensive, and troubleshooted headphones should work. However, I have been having intermittent Bluetooth issues since I got the headphones. It is infuriating. I have spent almost as much time trying to fix the problem as I have enjoying the many pros of these headphones. Bose needs to work on this issue and prevent it from affecting any future customers. As a first time product from them, I wouldn't purchase the brand again after this experience.
