There is the sound here indeed some meaningful reviews audiophile reviewers, I will not add much. Normal listeners I find the sound with a wide frequency range really good and the volume is sufficient. Also agree with many reviewers that the contact pressure considerably and the headset is nothing big ears. If possible, you should try it out before buying. The NC works the way you can expect in this price range.
Why do I write this review but at all my anger at the 3.5-input socket into which the detachable cable is plugged. This is so tight and narrow that no commercial substitute cable fits. So the functioning of a 100 Euro product depends on that cheap accessory adapter cord does not break possible ;-(
