Sound is balanced and clear. Noise cancelling is incredibly effective. Comfort is sublime. Love these for work and commuting.

Not great handsfree talking on the phone. Speakers and noise canceling is superb, but micrphone is shet

the QC 45 noise canceling and comfort are great... sound is good (my Grado admittedly are better) but these are still very good!

I thought they would have better quality sound. Didn't seem to be as clear sounding as others that I had listened to.

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

I purchased the earbuds first I like them but I live the headphones better great quality just wonderful headphones

Sound quality is very good. Comfort is good, but pairing TV, iPhone and iPad was a pain along with switching between them.

This item is the best I've ever had! It has amazing noise cancelation, great base, calls are heard well and are enjoyable

These replaced old Bose noise canceling headphones. Wish I had done it sooner. Noise canceling is very good.

My wife got these for me, they work great. I really enjoy the sound and noise cancelling feature. Hopefully they last for a long time.
