I purchased these headphones almost a month ago. The only noticeable concern I have, so far, is sweat leaks into the earphone and, then, into the ear. I lift the earphone off my ear to wipe the sweat from the earphone. Yes, this product is Quiet. No, it is not sweatproof.

This is my second set of Bose headphones, the first set I’ve had for 6 years and I beat them up pretty bad they still work great but the ear pads were disintegrating and the screws on one side began to fall out. I bought a new pair because I love them. During my purchase I saw replacement ear pads, got those too and between the new ear pads and replacing so screws they are like new.

I purchased this over three weeks ago and they have been on my head every minute since, even fell asleep in them. Simple to use simple directions product feels good. Looks good. Sounds good. Holds charge. What’s not to like. Make the leap and a Bose headphones you won’t regret it...

I have had these headphones for two weeks and they block out every bit of overhead noise from Regan Int'l Airport. They paired seamlessly with my TV and phone and now I have absolute peace and quiet while at home. Even though I'm out and about in mass transit, I don't use them, I'd much rather be aware of my surroundings while out and about. I will take these along on every plane trip I take. Take the time to fold them correctly in their case.

One of my favorite purchases ever. I had gone through 3 pages of cheap headphones and when I decided, despite my extremely limited budget, to get these as they were significantly on sale, I couldn't believe the difference. I could not only hear each instrument and voice without losing any of them, but heard lots of subtle touches of sound that simply didn't register on anything else, even a good pair of earbuds I was able to buy with a gift card. None of those stay in my ears. A bonus is that these are the first headphones that adjust small enough to stay on my head without being held in place with a headband.

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.

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.

Owned these for a about a month. Only problem is the dual connection. Doesn't work that well. Also causes connection issues by stopping my music from playing even if the second connection isn't near. Overall great. A nice balanced sound. At first I wanted more base but after tweaking some things it's perfect. Noise Canceling could be better but I image the pro version is better

I've owned 4 iterations of QC headphones. My newest purchase doesn't feel as solid, does not keep as much sound out. I put these new ones away and am using my older ones. Bose headphones are excellent overall, but it seems they've lost the level of quality that made Bose products the brand to have for excellence.

The Bluetooth interface and the sound quality are all great! The toggle from aware and quiet mode really showcase how efficient quiet is at noise cancellation. My only complaint is while the headphone pads feel comfortable on my ears at first, I can’t wear them too long because they do start to hurt after a while.
