Your question is worded very oddly, but to attempt to answer it, headphones (most) operate off of an analog signal from a DAC (digital to analog converter). In any analog setup you’re going to have some amount of signal transmission or line noise unless the two transmission lines are entirely shielded or entirely separated.
Ah, wasn’t sure if they shipped with their own version of webkit for compatibility or invoked the system call. Unfortunate that it’s the latter.
