Excellent quality for noise cancelling and sound quality. My second pair as I keep my 35 series at work. Love these new 🆕 and improved 45 series

Great fit and great sound quality with a balance of bass and treble. The battery last longer than other headsets or in ear devices like AirPods.

Just amazing. Comfortable. True noise canceling. You will forget you have them on as you are immersed into another world inside your mind.

I loved the headphones amazing audio quality I forget I'm wearing headphones from how in sync I am in with the music

[This review was collected as part of a promotion.] Everything I expected form Bose. Great quality, comfort, sound and noise cancelling.

Very happy with the sound quality and ease of pairing with my devices. I've always loved the “Bose Sound,” and these did not disappoint.

Amazing sound…as well as amazing noise canceling.my other headphones were Sony.after my new Bose experience you guys have a new customer for life!

Bought a week ago and love them at work all day long. I can listen to my music, take phone calls, here's what's around me. All around great product

I bought these headphones after trying out multiple different in ear and over the ear noise canceling headphones and these are by far the best. I use them for working out every day and coukdnt be more happy with them.
