Special thanks I want to say to the guys from the store. After a month of use, after ating the software on the phone, multimedia with headphones stopped playing, they tried everything at home, even reset the phone to factory settings. At the same time, the headphones worked perfectly with other devices. Despite the fact that the problem is obviously in the phone, I wrote in support on the official website, on the same day they invited me to the store, which, by the way, is very conveniently located next to the metro station on Tsvetnoy Boulevard. In half an hour, having rummaged through the phone settings, they corrected everything, explained what was the matter, so that I could fix it myself when I repeat it, everything works fine again, I continue to enjoy our headphones!
