At first it was not very comfortable to wear, but over time, the headphones sat down on the head. The sound is completely satisfactory. I have been using it for 4.5 years already - a very high-quality assembly, as well as the materials themselves. The kit comes with three wires. After a year of use, a short wire frayed - I had to use a wire for a computer: it still holds) In fact, all the other headphones I had lasted an average of a year: I am a very sloppy user. So the quality of the materials is excellent.
