They sound really good. Noise cancelation is top-notch. The app, however, is dollar store trash . Companies like Soundcore and Tozo have apps that are light years ahead of Bose. For example , Tozo has custom EQs from around the world from other users to choose from. Their app has custom modes such as wind noise reduction , adaptive mode , customize your own EQs, and more. If intuitive app support is important to you, then look elsewhere . If not, then these are great. I expected more from Bose, and personally, I am disappointed.

Great product but the battery life is too short. Good noise canceling

I have had them now for about a month. I love them! I feel like I'm in my own world

I like them a lot but they aren't tite enough for my head , also they could be a little louder!!!

Great price for this gift

Purchased 30 days ago and am very happy with the sound quality and comfort.

So farThe product seem to be working well very comfortable.Lightweight sound quality is above fair.

I’ve only use them twice but the noise canceling is amazing

I bought two Quiet Comfort headphones and we are both in love with the comfort and the sound!

I bought this three weeks ago and love every moment of using them. They really works well
