But the noise canceling is so good that I have to say: Hardly any other product I've ever bought, has changed my life so positively. I wear the headphones at least five days a week up to twelve hours (in bus and rail and in the office while working on the PC). It is so much more relaxed. Makes that noise sick, is not a new Erkentnnis.
As another reviewer wrote: The only thing I regret the purchase, is that I have not already purchased the headphones earlier.
