I had this same issue kind of issue. I spent time finding different audio sounds for like water extraction and those did little of anything even when paired with alcohol(carefully lol). I just gave up and went for the Hail Mary of an idea after noticing the little hole behind JUST behind the silicon/rubbery ear piece.
I put it up to my mouth(already clean from alcohol don’t worry) and blew as hard as I could. I then noticed that the earphone bit started having stuff blown out of it. Put it in my ear and I could hear again. Did it a few more times until it wasn’t pushing anything else out. Prolly safer to use like a basketball pump or something that won’t push too much pressure or push any liquid into them.
Not official advice btw do at your own risk!!
