I'll just be straight with everyone, it sounds amazing, the noise canceling is great, it can easily be turned off. Battery life last long and I'm using the app, so it helps to keep track.

I love the design and feel. It's easy to use, and light. My other headphones were heavy. Also, it folds and packs easily for travel. I love it overall, I've only had it for a month and I wonder why I purchase it sooner.

(This review was collected as part of a promotion.) My old bose qc 25 was broken a month ago, after around 4 yrs service. I lost my soul until I get my new qc 45, which brings my life back again.

I got them for Christmas & they work perfectly. The sound is crystal clear & I can have complete shut b out of background noise or I can hear some. A smart option.

The sound is tinny. No one can understand me on calls. The sun cancellation is really just bad interference. The battery life is terrible. They simply don't work. I got as a replacement for QuietComfort 35, and I couldn't be more disgusted.

I bought the Quiet Comfort headphones a few weeks ago. They are everything I had hoped they would be. The sound is amazing and the noise cancellation is super effective. So glad I bought them.

I use these daily, they are comfortable and the sound quality is excellent. It's nice to have a product that holds a charge for longer than an hour. I can use them a few hours daily and charge them once a week.

Good quality sound and confort, and I like black color

Love Bose, I have a few products from them and always been satisfied with them.

Great sound, love these! Wish I had bought a pair sooner.
