For the beginning I made some holes in a mesh on photo little bigger using medical needle, after I cover this mesh by 3% hydrogen peroxide, turned on the program with bass and hies for about 10 minutes, then I blew these meshes with this blue thing (I don’t know how it’s called in English), and after that, for the first time in 2 years, my headphones give out clear sound in transparency mode without distortion and for the first time in several years they passed “fit test”, before this I replaced them 2 times and now I had nothing to lose and I tried, and it works, so do everything at your own risk
