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.
