I'v never seen any apple product fail from water. I remember my friend accidentally dropping her original iPhone in the dishwasher and not noticing and running it and it still worked after!. every pear of EarPods I've had has gone through a washing machine and all worked fine after.. and my AirPods get soaked in sweat at the gym or in rain all the time with no issues. Modern stuff like the watch and iPhone XS I don't even think twice about getting wet. they always work fine
