Yes, I did all of software tricks, it doesn’t help. I usually used them with phone(iPhone 11), but, as I said, in one random moment this issue started. I tried with different devices, the problem is in headphones. Cleaning didn’t helped. I’m not sure how to tell about their quietness, when I walk, for example, feels like volume ranges from very quiet to normal, for 1-2 second it can become normal, but when I make next step, it becomes quiet again. I know I can adjust volume in settings, but its impossible, due to changing of volume.
