I have these beautiful headphones already about a year and am satisfied. You make a (my opinion) very good form. However, they did not seal - what I was hoping. I bought the headset for the office to turn off when others are talking or any other reason is a bit of noise. This works well so far, but if you have more quiet songs that listeners are crap. You can hear everything that is through! If you are with the idea somewhere else anyway, it goes, but as you have to arrive first. ;) 4 stars for sound and processing. 1 star deduction, because you can forget the headphones for quiet songs with quiet passages when there is background noise.
