Being careless with where you put it after you're done jacking off if I had to take a realistic guess. It's a unrealistic meme I've never taken seriously this happens anyway.
>Oh and how do you clean your headset?
Same way you clean anything electronic and plastic, you wipe it down with antibacterial wipes, preferably the ones meant for electronics. Glass you wipe down with glasses cleaner. As for the soft facial interfaces, you really should buy new ones if you're buying used regardless of the times or not.
