Hello forum!
My sibling broke their earphones and I am trying to repair them, but cannot understand on which solder pad should I solder the "golden" wire, because the pads are identical to me. I looked for schematic online, but could not find one and since these are fake I guess there won't be an accurate one. The earphones were ripped from the microphone area. There are two ripped wires - one blue and one golden. Because the speaker needs two wires I suppose the blue one was the missing one from the speaker (there was one wire ripped from the speaker area too) , because the golden was still on the speaker. The golden wire is on the speaker but ripped from the microphone's pcb. I see two solder pads on the pcb and they look identical. My question is which of the pads should the golden wire go to? I Will be very thankful for any help!

 

Your photos are too poorly focused to be helpful. Look for areas where the wires could have been pulled from and use whatever hints you have available to you (e.g. wire lengths, connectivity) to guess which goes where.

I made new pictures in hope of better quality. I am hobbyist so I do not have microscope and cannot zoom a lot. One of the wires is too long for the board (blue one). The other on the other hand is Just the right length for the both solder pads. So I can not be sure which one to pick.

Also how to test the connectivity. I should plug the Phone and play music?

You can try to determine what the other ends of the loose wires are connected to. If you have an oscilloscope, you could probe the places where you think the wires might have been disconnected from.

I have only multimeter.

Can you get an oscilloscope? Not having the appropriate equipment will complicate things.

I do not think it will be possible. I Will take my chance and solder to one of the pads that seems to me has lost the wire and try it that way.

It's broken, so you don't have much to lose unless it's repairable and you manage to damage it beyond repair. Try holding the wires in place before soldering.
