dead earbud was just oil-clogged

2.27: proj.gear/ear bud/left side is dead:
. the left side is dead ?
no, you can barely hear it though;
so, check inside the sound canal:
it's packed with foam that had gotten
totally saturated with oil
(the anti-bacterial ointment oil)
-- I thought that stuff was just drying up!
. the foam tips I got have a screen that will not keep oil out,
but that screen will hold in a piece of foam;
and, the more of that there is
the safer things are from oil penetration .
