I am generally satisfied with the headphones. Usage nuances: - you have to wash your ears every day, otherwise the headphones will not fit tightly. :-)) - they also "slide" from their places when chewing. - about noise reduction. Low frequencies are cut off very well (close to 100%), and medium and high frequencies are cut off by about 30%. I think they did it for safety. Interesting effects are obtained - for example, a truck drives by, rustling tires, and a vacuum cleaner is heard well. If you go out on a noisy street, it may seem to you that there is no noise reduction. Turn off the noise reduction and you will understand the difference. Noise reduction is well suited for street and similar noise (even away from the streets it is), but sometimes it even enhances jerky sounds - for example, the sound of a hammer or a "ragged" wind in a train window. When watching a video, there is no delay: the phone adjusts the picture to the sound in a few seconds. I won’t say about games, because. I don't play.
