I have been looking at these headphones for a long time, since the 3rd model. Before Sanya, I myself actively used Samsung Galaxy Buds, less often full-size hd280pro synthizers. I expected that the sound would definitely be better than the Samsung, there is nothing to compare, but the fact that it would be better than the sinhs was a surprise. For a long time I did not have a moment when I just listened to music and enjoyed it, usually the music was in the background, and I was doing other things. Not so with Sony, now I just like to relax listening to beautiful music. And for me, now many tracks have opened from the other side, the sound is radically different, I love the basses, the mids and tops are chic. I use headphones all the time now. I am very pleased with the purchase, I took it for 17k in the store for a promotion in December 2022.
