So the headphones are still working well, but the speed of customer service and the communication of the service, in particular Anton, are disgusting, to put it mildly. It turns out that you pay 10 thousand and sit without headphones for 1.5 months, absolutely not your fault. Its pros: I liked everything, the sound, how they sit, materials, etc. and so on. . but there is one but! With its cons: The disadvantage is that after six months of use, when working with a microphone, the sound in the right earpiece began to disappear. Well, I think, I happen, they will quickly replace it . I took it to the OFFICIAL service center (3G Zone) where they told me: "everything will be resolved within 2 weeks." And now 41 days have passed, a bunch of my calls, asking when? And in this service they tell me that SENNHEISER does not send new headphones, since these are recognized as defective.
