weird question about wired earphones... (lemm.ee)

So I had this JBLs, one earphone of which stopped working a couple months ago, and I just left em laying around later to be recycled. Today I tried them again and lo and behold, they work perfectly now. Is there any reason why they do act like that? (FYI I used these extensively while running)

My guess, the internal wire likely has an open in the copper somewhere. But since it's wrapped in rubber, the copper wires are still near each other. So it's working right now, but I'd bet if you wiggled the wire it'll cut out again.

Actually tried that. Still works.

Huh. No crackling at all? That is certainly weird. Sometimes electrical things that are acting weird, start just working correctly again. Usually when I see something like that's it's a physical problem not electrical. Think about it like rust in a switch, you move it a bunch, the rust falls off and the switch works again.

So my thought is that you got water, or more likely sweat, onto the actual speaker. Which then hydrolocked the driver. Maybe the water finally dried out and the salts dried, cracked and fell out when you finally tried it again.

That's a total guess and I have no way of proving it.

I thought there would be some crackles, too. Really tried bending the endpoints near the phones and the jack but still works.

I mean Im glad it works again. My danky philips had the mike unit torn into half so... I should be more easy towards my electronics i guess
