Good headphones, I recommend. I like the sound, now I'm used to it and it seems like it seems ordinary, but at first it was cool. Noise canceling is also excellent. The subway is fine. At work, the people around you can not hear. The radio in the office, if you can hear that it is working somewhere, but you can’t make out the words. The charge lasts for three to four days of active use. Of the shortcomings - sometimes the noise canceler hits the ears, with certain noises. IN
