Originally bought a pair ~2 years ago on sale, they worked perfectly the whole time I had them before they were stolen a year later. Finally decided to replace them and the noise cancellation on the new ones is no where near as good. Disappointing especially having paid twice the price this time. The old ones were great for studying in crowded areas. With these, even on the highest setting I can still hear just one person talking at a normal volume in the same room. The audio is good quality still but given that the noise cancellation barely works, definitely not worth the price.

Very good product very comfortable excellent sound I only gave 3 stars because auto off doesn't work I set it in Bose app all different to all different times and it stays on all night and wares down the battery I have to remember to turn them off manually

I'm an autistic adult and have sound sensitivity. I had my doubts that noise canceling headphones would be significantly better than the cheap headphones I've worn for years. My wife persuaded me to spend the money. Once charged, I put them on and I heard silence for perhaps the first time in more than 60 years. The constant bombardment of noises that most people never really hear - electric fans, buzzing from overhead light fixtures, "background music" in almost every store. I never knew that the pain could end. My wife's first comment was: "worth every penny". I agree.

I have been using these headphones for the past two weeks. I am a Bose fan. However, I am very disappointed in these headphones. While the noise canceling feature is good, I find that the quality sound that Bose is famous for is woefully lacking. They do not measure up to other Bose products that I use, including the Bose Wave and portable Bluetooth speakers.

Bought these because earbuds irritate my ear canals. Didn't think I would love them this much. Last time I used quiet comfort headphones was gen 1 way back in the day, they've become SO much better! I absolutely am blown away by the ANC features and "wind mode".

I bought the Bose Quiet Comfort Headphones and I'm so happy with my purchase. I actually returned another popular brand of headphones before purchasing the Bose Headphones and I'm so happy I did. I have other Bose products in my house that I am extremely pleased with and I just knew I couldn't go wrong with the decision to purchase the Bose Quiet Comfort Headphones. I look forward to working out daily because of them. They are comfortable and lightweight.

I bit the bullet and bought these on Bose's last sale. I'm so glad I did. Return to office has been brutal and these headphones help me concentrate even when people are inevitably talking around me. They are very lightweight and the over-the-ear style is comfortable.

The headphone sound and noise suppression are fantastic. But I don't like not getting an in-the-box operating manual. The idea having to depend on the internet and scanning codes for setup information is irritating. Say in 3 yrs from now, if I have an issue or question with the headphones, I want to go directly to the hands-on written operating manual. Maybe not having an in-box manual is the future. Could it be that today's youth can't read or comprehend detailed written information?

Bought a set to replace the 10-year old pair my son decided was his own. I've always loved the bass and dynamics of Bose sound whether audiophiles like it or not and have been devoted to Bose products for 25+ years, but something is different. There was a tinny sound and a weird buzz and despite all trouble-shooting, could not re-create what I had with my old set. The sound was distracting, annoying and gave me a headache after a couple of minutes. It could be that these were defective, but after trying some Sony's, the Bose product just seems inferior now. It was good for decades, but not sure if it's good enough anymore. Returned for refund and replaced with Sony's.

I bought these headphones specifically for working out, and overall, they’ve been great. The noise cancellation is absolutely top-notch seriously impressive. Once they’re on, I can’t hear a thing around me, which really helps me stay focused during my workouts. That said, there are a couple of downsides for exercise use. The ear cushions tend to get pretty sweaty, especially during intense sessions. Also, when I lie down on a bench, the headphones don’t stay on very well they tend to slip off, which can be frustrating. Still, if noise cancellation is your top priority, these are some of the best I’ve ever used.
