I looked at the markings on the EarPods plug. It is possible that there's some electrical arcing here? To check this out, plug in the EarPods and play some music in a completely dark room while looking closely at the headphone jack area.
Gavinj- This is exactly it. I am on my third 5S right now and it is clear that running is the issue. I didn't recognize it at first but now I've had this failure 3 times and they are clearly tied to running. But even still the issue is not so simple... I take good care to protect the phone while I'm running, but just now I was jogging on a treadmill and in the middle the volume controls stopped working. When I checked the jack, yup, corroded pitted and deposits.
Here's what I think is happening - sweat is getting jn the headphone remote and causing a short that is leading to increased potential in the jack and that is causing the corrosion.
For the record: I don't live near the coast, I don't work or live around any chemicals, in fact the environment I subject this phone is identical to what my 4S saw and I never had any problems. I am using the apple earbuds.

Stan,
What case did you say you were using? Is the iPhone strapped to your outer Arm? The Jack is now on the bottom (maybe this is why Apple moved it, to prevent Sweat unless Upside Down).
If I recall you used an iPhone 4 or 4s previously but never had this issue.
Oh, and by the way go easy on the electrolytes(sorry I couldn't resist)!
