I took it mainly for work, meetings and conferences. In addition, I decided to watch movies and listen to music in them. After intensive daily use, I can draw the following conclusions: 1) Sound - comfortable, in any sound, whether it's music or conferences. 2) the buttons are convenient, you can not keep the conference window constantly open, but on the button turn the microphone on / off 3) Effect 7.1. - many do not understand why it is needed. I can say the following: in music it is not needed, because it gives the effect of sounding like in a tank, at conferences - the sound is more voluminous, but no more, but in movies and cartoons - I like to watch with the 7.1 mode turned on. - the sound from a flat track turns into a "presence effect"; even small sound vibrations become distinguishable, which, during normal listening, are either very quiet or completely absent. What gives its zest. Bought in amazon with a very good discount. These headphones are worth the money even without a discount, because the price = quality ratio works. Definitely recommend to buy.
