I have had the headphone for 3 year and some months now, and have started expiriencing crackling issues, which i believe are due to the 3,5mm jack deteriorating. During listening the audio crackles, more during sudden noises and sometimes gets worse/better when i rotate the jack inside the port. I've checked all pc audio ports and the issue persists. Very noticable if i lightly unplug then rotate it, a lot of crackling. even during fully plugged, rotating it causes it to be worse. I've also plugged it into my nintendo switch, which it only crackled if i pressed the power button on it. There is a cable replacment on the official Sennheiser website, but is there a cheaper alternative that is still good? I'm willing to buy the official cable if really need to. Poland.
