I use this headset for only a month. The soundproofing is excellent and the performance is more than satisfactory. The ability to adjust the headphones seemed very helpful at first but with use, has not proved very practical. The headphone is too stiff for my taste, which does not listen with one ear when the headset is around the neck (but maybe that is it I'm using it .... wrong) And then in the long run, it serves as the head and ears, especially if you wear glasses (I said that I did not, however, a big head!).
I used with headphones Technics mixais more or less low end, the quality was less than this model, but whose use was easier. Now I lose precious seconds in the mix to try to wedge one headphone on my ear. It's not really the desired effect!
