"Eternal" headphones, alas, do not exist. Even if they are very expensive, sooner or later a break will appear in their cable. Especially often it occurs next to the plug. Due to such a malfunction, changing the headphones entirely is as impractical as changing a cell phone due to battery wear.
Instructions
Step 1
Make sure that the break is located exactly in the plug. If it is located even a couple of centimeters from it, it is more expedient to eliminate the break in the cord than to change the plug. To locate the break, lightly wiggle the cable in different places.
Step 2
Disconnect the headphones from the device before repairing.
Step 3
Purchase a new headphone plug. It must be of the same standard as the faulty one (stereo, Jack). Monaural will not work. The new plug, unlike the old one, has a collapsible design. Please note that the new plug must also have the same diameter as the old one (6, 3 or 3.5 mm).
Step 4
An alternative to purchasing a new plug is to use a matching part from other headphones. Find among the defective headphones you have, those in which the break is not located in the plug, but in another place. Cut a short (about four centimeters long) piece of cable from them together with the plug.
Step 5
If you are installing a new plug, cut off the old one and then remove the cap from the new one. Pass the cable through it and also through a small piece of conduit. Solder both clear or yellow wires to the post. Solder the blue or green wire to one of the small contacts, the red or orange to the other, also pre-putting pieces of tube of an even smaller size on them. Then pull these pieces of tubing over the soldering points. Move a large piece of the tube closer to the stand, and then clamp the cable through it with the tabs on it. Do not overdo it. Screw the cap back onto the plug.
Step 6
If using a plug from other headphones, connect all yellow or colorless wires of both cords together. Separately connect the blue (green) wire to the same wire on the other cable. Do the same with red (orange) wires. Isolate connections securely, including from each other.
Step 7
Connect headphones to the device and check.
