They are perfect! I love how they fit, block outside noise, music sound is incredible! Worth every penny I paid for them. Wish I had bought years ago!

I purchased these about a month ago. They work well but not as good as expected. The fit on my ears is a bit awkward and they are not true noise canceling but they do eliminate some of the background noise.

The quiet comfort headphones are amazing and incredibly comfortable to wear. Absolutely love the quiet/aware feature and sound is crystal clear. The battery life is impressive as well, lasting a long time between charges.

The headphones worked great with Bluetooth however, I was looking to purchase headphones that had a cord adaptability to iPhone to avoid Bluetooth. I soon found out I needed to buy an adapter to plug into my iPhone, which I purchased two different ones and they keep disconnecting from the Bose headphone wire. Not very happy with my intended purchase and the cord connecting to iPhone.

I bought these for work. I enjoy listening to music and taking phone calls without having to worry to much on my surroundings. Obviously loud noises will be picked up. It quiets everything for me to concentrate. It is not entirely noise canceling as you can pick up some noise and conversation but not distracting.

Really great and stylish headphones. Really good quality sound as well. Took off 1 star for the case. It doesn't fit the headphones so easily as it came in. I know the upgraded model of this has slots to make it easier to put those in, so kind of kicking myself I didn't go with those. Either way though, these are great overall.

I purchased this as an upgrade for my mom. She had her previous pair a long time and was happy with them but then she got a puppy who got a hold of them so I got her the new pair for her birthday. She loves them so much and I'm glad I got them for her. She says they are comfortable and loved the noise cancelling they provide especially for flights. They also honored the price match without hassle when they went on sale from the price I paid.

I have Parkinson's Disease and am hard of hearing. Even with hearing aids I could not hear or understand what people were saying over the phone. I bought 2 headsets from other manufacturers. Not only could I not hear what the person was saying, they could not hear me! My husband always took matters into his own hands and bought me Bose Quiet Comfort headphones. The headphones have a built in mike.. I was never so pleased with a purchase! They work beautifully!. The sound is incredible! Even just conversations sound incredible!

Bought for my wife because she always liked mine, which she bought for me many years ago. She tried them Christmas Day and was disappointed. The noise cancellation doesn't work like it does on the original. Sorry! I know you've heard this a lot but it's true. We both tried side by side and it's a large difference. It's like the new one doesn't work at all.

I have had Bose ear buds for a long time. The sound is far better than anything I’ve owned before so I couldn’t wait to get these headphones . They are so clear and the sound is amazing! I can actually hear parts of music I never heard before. Well made and great quality.
