I was tossing up between these and the Sony XM3s, and I chose these because of their lower price. The build quality and comfort are quite good, although I do feel a slight pressure on my head, especially if using them lying down. The noice cancellation works great, and should be amazing for when I have to commute. There is a button to control the noise cancellation level (off, low, high) but to that button to control your digital assistant you have to give up that functionality, which I dislike (would have liked a designated button or key press sequence activation). The audio quality seems good although I am not an audiophile and am comparing them to my iPad speakers. All in all they are quite expensive but I’m happy with my purchase based on the noise cancellation, comfort and easy Bluetooth pairing.
