I often listen to my iPhone while editing my radiology reports. At other times, I carry my earbuds draped around my neck like one of those internist dudes carrying a stethoscope.
This backfired last week during a call of nature, when my earbuds slid off my neck right into the line of fire, shall we say.
Oddly enough, the Apple website doesn't have a single tech support note containing the word "urine".
So, I cleaned and dried my desecrated earbuds as best I could, using simple nearby tools. Once I felt safe putting them back in my ears, the left earbud was dead.
The main silver lining for me is that the iPhone itself stayed in my pocket. Otherwise, I have a feeling that this would have totally voided, so to speak, my warranty.
