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.

If you put the yolk into a cup of soil, you should have baby headphones within 2-3 weeks.

[-] [email protected] 42 points 1 year ago

You gotta be careful with baby headphones. If it's a boy, he'll keep the cord. If it's a girl, she'll loose her cord, and her teeth will turn blue.

In some states, you're legally required to.

Makes me think of that shitty grippy rubber material on cheap mice that becomes gooey with time. I would treat those as euclid until further testing

Euclid??? The greek mathematician?

[-] [email protected] 66 points 1 year ago

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.

.......what is an SCP?

[-] [email protected] 30 points 1 year ago

Secure Contain Protect

SCP is a collaborative wiki fiction edited and written by lots of people for years now. It started as kind of a novelty, a fake wiki of heavily redacted files relating to an organization's attempts to contain cryptids and various weird things. Its evolved over time and has numerous narrative arcs etc now.

Is......is this what you guys were doing during covid quarantine? I just....played animal crossing.

The SCP Wiki is over 16 years old now!

I made shit up 16 years ago too! Everyone did

[-] [email protected] 16 points 1 year ago

It’s actually a pretty old Internet Internet project!

SCP-3008 The Perfectly Normal IKEA, and SCP-3333 about a spacial anomaly on a fire tower are my 2 favorites, but I haven’t delved all that deeply either.

Happened to my mate, it sucks a lot tbf

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.

[-] [email protected] 37 points 1 year ago

These are earbuds, not big ass speakers. There shouldn't be enough power going through those cables to do melt anything.

[-] [email protected] 14 points 1 year ago

You would be incorrect. If the power source shorts, it would heat the wires sufficiently.

[-] [email protected] 12 points 1 year ago

And how much power do you think the DAC in a phone is going to output?

The built in DAC in a phone can barely drive my headphones, let alone melt a silicone cable. They typically output less than a watt. On a good day. Rubbers melting point is 365c and 1 watt isn't gonna do that.

[-] [email protected] 9 points 1 year ago

They typically output less than a watt.

Sounds optimistic. Checking a few USB to 3.5mm dongles, they seem to be around 25mW max at 32Ohms. Not sure how much that would change with short circuit, but I guess not much more.

[-] [email protected] 1 points 1 year ago

It's more to do with wire gauge...

[-] [email protected] 0 points 1 year ago

Have you verified the specs on OPs headphones?

Maybe I missed it but I don’t see where OP said this happened while connected to a phone.

[-] [email protected] 9 points 1 year ago

They're earbuds. You're going to using them with a phone, maybe a laptop, or even in a pinch maybe a desktop. None of those output enough power to melt through a rubber cable without severely destroying themselves and never working again. OP would be posting "my phone exploded and I'm deaf now" not about the cable having a pimple.

Even my dedicated amp, a Shiit Magni outputs 6 watts with both channels combined, and ain't nobody connecting shitty earbuds to an amp. The rest of the cable is going to sink away the heat from 6 watts before the rubber could get hot enough to melt.

[-] [email protected] 5 points 1 year ago

Doesn't explain the goop though

[-] [email protected] 25 points 1 year ago

Some sort of chemical reaction. My best guess would be a drop of CA glue that degraded the material over time.

[-] [email protected] 13 points 1 year ago

Sir, you are to remain in your present location until MFT Psi-8 makes contact. Any and all resistance will be met with force!

[-] [email protected] 13 points 1 year ago

I feel like you maybe should replace those...

[-] [email protected] 9 points 1 year ago

Flux would be my guess

[-] [email protected] 9 points 1 year ago

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.

[-] [email protected] 8 points 1 year ago

Extra warm conditions?

[-] [email protected] 2 points 1 year ago

Nope.

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.
