I replaced my old Bose headphones with this model and am very happy with the Bluetooth feature as well as the smaller case. It was easy to set them up and connect with my phone. We travel a lot and find the headphones invaluable.

Best headphones I've had for comfort and sound. Noise canceling very good. Audio quality very good for various music types including vocal and instrumental classical.

Love these headphones! Sound quality is really good. You can adjust bass, mid, and treble a little bit. I like a lot of genres and it's nice to change accordingly. Comes with a cool case, and an aux chord and charger.

Nice unit - works well but I wish I had more control over the level of noise reduction. It essentially allows for only on or off. Also, I wish I could still listen through the headphones when battery power was gone.

Do not fit securely on small heads. Female 5'1” 117 lb. Certainly are NOT noise “cancelling “ as I can still hear what is going on around me with them on. Disappointing for the high price

Easy to use and excellent noise cancelling functionality. They're also very comfortable. I held back on buying them long ago because I had the mindset of, how good could they possibly? Well...they're pretty darn good.

My QC35's finally gave up the ghost after 10 years, so it was time to find a replacement. These are an excellent choice, comfortable, great sound, and an all around great headphone.

These headphones are an amazing product, they have amazing noise cancellation, I love that you are able to adjust the sound quality of the headphones.

I got this for Christmas and have just started using it, this thing is REALLY good. Surprisingly good quality. And having a quiet mode on this is really useful when I'm around a lot of people. And all of the button shortcuts are really useful.

I received my QC 45 two weeks ago and very happy with the comfort and quality of sound. I love the ability to easily turn the noise cancellation feature on and off. I also like how they fold up in a nice carrying case.
