But be warned, their customer support is terrible if you don't live in Europe.
They cost more than I paid for my top end AudioTechnica's.
(For a while I thought things like Coffivity were a good idea to restore the ambient noise I was killing out with perpetual headphones...but then I realized what I was doing to myself, and felt kind of ashamed and embarrassed.)
My experience is different. I'm a person who is very sensitive towards noise (even in the classroom writing tests was horror). I personally consider silent environment + good noise canceling headphone (for silencing all the remaining noises that are still there - you are surprised how many there are) as comforting. The static noise that any noise-canceling headphone will produce is the smaller evil here.

> Noise canceling headphones are much more effective on constant noise like an airplane engine than transient noises like speech or phones ringing.
Also my experience. They decrease the noise of speech and phones rining, but that's it.
I wear my headphones as earplugs on an airplane when I want to sleep, and I can usually keep my volume at 10% of max or less and hear everything crystal clear.
The biggest downside is that my headphones cost $350 and are only available in Europe or Montreal, CA.
