Not noise canceling at all. That's why I bought them so 1 star..the only way they cancel noise is to play music pretty loud.. they are comfortable and sounds great.

[This review was collected as part of a promotion.] I love these headphones! I have always had issues with headphones giving me a headache and I do not have a problem with these!

I bought these about 3 wks ago. We live in a small trailer, with these headphones I can blow out my head while my better half is contently snoring away. They have the Bose sound and the quality is there! You've got my complete endorsement.

Comfortable, the sound is great, using the app to fine tune the sound you want makes this even sweeter! Love my Bose QC headphones! I wore them for a 5 hour study session and they were so comfortable. Love them!!

[This review was collected as part of a promotion.] They were ok for almost a year then just died. For something so expensive shouldn't it have a longer lifespan?

[This review was collected as part of a promotion.] I bought these in October and I love them. I stream from YouTube while cleaning and the sound is crystal clear. Bose makes cleaning enjoyable for me.

Purchased these a month ago because I had left my other pair on the delta flight in the seat back. These were actually an upgrade from my last pair. This are excellent clarity and depth in tone.

I myself loved the headset but my wife who I purchased for, has a previous brain injury and can only wear them for less than a half hour, have to figure how to get her to wear some kind of beanie cap

[This review was collected as part of a promotion.] great noise cancelation, super comfy and light, good sound quality and the auto switching bluetooth works great

Use it for working in a call center. Great quality sound and my voice is clear using the mic cord. I just wish I could buy another purple mic cord for a back up. I’m sure this one will wear out in a year from daily use.
