I have long wanted ears with active noise reduction. After seeing these headphones and reviews decided to take and was satisfied. But there is one small "but" - this is atm stabilization. pressure with noise reduction and "environment" turned on. Either my ears are very sensitive to this, or on my headphones it is slightly twisted, it presses noticeably on the membranes and, after prolonged use, the ears themselves may ache. There are no complaints about noise reduction - it works great. The earphones themselves sit quite comfortably, I spent the whole working day in the office and sometimes forgot about them.
