Insane noise cancelling, fit and comfort. Feels like each instrument hits a different part of the ear.

Purchased these about 30 days ago. Bose lives up to its products upon each and every purchase I make.

Tactile differentiation of stop/start/answer phone button needs to be enlarged compared to size of volume up/down button.

[This review was collected as part of a promotion.] These headphones were a Christmas gift for my wife. In my trial they certainly functioned well.

They are perfect for most people very good sound quality with punchy base makes the perfect for most

I am so happy with my QC 45. Clarity of sound and comfort is what I love most. Battery life is just fine for me since I use it not so frequently.

Sounds quality is amazing. Comfort 10 out of 10. Noise canceling tech on them is the best on the market. Bose's customers service is also top notch.

Living upto the Bose standard in audio perfection. P we personally think the audio and sound cancelation is superior to Sony.

So glad I purchased these headphones. Very comfortable to wear, great sound and love the noise cancellation feature.

They are the most comfortable over the head headphones I've ever owned; and I've owned a lot. Sound quality is Bose.
