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)
There is probably a short in the cord. In my experience that tends to be a common failure point in that system.
Yes, that’s the most probable explanatiom imo
So does it mean in wired electronics sometimes when there is a short you need to wait it out after a good amount of use?
No, it’s more that there’s a problem with the wires or the solder points. Since you said you messed around with the wires quite a bit without any impact, it could be that the short is in the solder points either in the buds or in the plug.
No, a short is a break in the wire. The wire is made up of multiple strands of copper, like a rope. If you shift the wire around, you can cause them to touch and continue to conduct. If the short isn’t very bad, this can be an intermittent issue, as time goes on it will get worse.
Low voltage electronics, like earbuds aren’t that dangerous. I was using a drill recently that I knew had a short in it and was just moving it around to make contact so I could finish the job. The cord eventually caught fire and I had to replace it.
