My earphones' cable has grown a pimple. It popped today.
Image on left is from 4 days ago, but the pimple was slowly forming over around 2 weeks.
The goop was sticky, not oily. Earphones are Panasonic RP-TCM130.
I was not able to find an explanation.
Something to increase cable lifespan, lubrication, rubber disintegrating, sweat and earwax that somehow got into the cable, dielectric grease, SCP-1407, no clear answer.
At first I thought the wires just somehow twisted. Nope.
Euclid-class SCPs are anomalies that require more resources to contain completely or where containment isn't always reliable. Usually this is because the SCP is insufficiently understood or inherently unpredictable. Euclid is the Object Class with the greatest scope, and it's usually a safe bet that an SCP will be this class if it doesn't easily fall into any of the other standard Object Classes.
High resistance in a wire inside the sheath would generate more heat at that point, causing the plastic sheath to melt/bubble. So if the wire inside the sheath got damaged, pinched or some of the strands of wire were broken.
I am so intruiged by the fact that the mass of good accumulated at the one spot. The mystery of what pressures were at play for it to flow to that one spot.
