Unfortunately, in my case, I have headphones with a non-working microphone. When you press the microphone with force into the socket, there is contact and there is sound. At first, after 5 minutes of rustling the jack in the socket, it was possible to catch contact and calmly use the ears. But recently I accidentally pulled the microphone out of the socket and since then the contact at the microphone is caught only when pressed by hand, which obviously equals the inability to use the microphone. Let's be honest - from a headset for 9k, I expected that it would work. Silly of me. Taking into account the fact that their sound is mediocre for their price, it turns out that there is no point in taking this model.
