In terms of ergonomics, a very poor model, taking into account the mediocre sound, it was made cheaply for 5000 - 6000, IMHO the level of cheap China for 1000 - 1500. Got pros: Large cups, no pressure on the ears, tolerable sound. volume control and microphone mute on the earpiece is convenient. Has cons: There is no rotation of the cups as such, if a person has a square head, then it is quite suitable, for 2 hours the head ached from the fact that. There is no software or drivers (at least under win 10 64x), that is, it is impossible to adjust the sound.
