For an active user, especially if he likes to move to music, even high-quality headphones sometimes “live” no more than a month. There is no point in buying new ones every time. You can fix them faster than walking to the store, thereby saving not only money, but also time.
Instructions
Step 1
Start repairing headphones after you have accumulated at least a few pairs of them. You can extract serviceable parts from them and then combine them into fewer pairs that will work flawlessly.
Step 2
Divide each pair of headphones in half in the middle. Pull all conductors out of the common shell, and then tin. If you try this first, you will find that the insulation interferes with the tinning process. You will be tempted to remove it with a sharp object, lighter, or soldering acid. Do not use either one or the other or the third. With the first tool, you, along with the insulation, will damage the wires themselves, with the second, cause oxidation of copper, due to which the conductor will stop tinkering even despite the absence of insulating varnish on it, and with the third, a short circuit, which will not appear immediately, but after a while and suddenly … Simply place the end of the wire on a piece of wood, and then slide the rosin-coated tip of a soldering iron over it several times with force. Rotating it, achieve the removal of varnish from it along the entire diameter. Then cover with rosin again, then tin in the usual way.
Step 3
When ringing the cables, be guided by the following pinout of the plug: the contact located closest to the cable entry into the connector corresponds to the common wire, the middle one - to the left channel, and the farthest from the input - to the right one. In the cord itself, wires in silver or gold insulation correspond to the common wire, green or blue to the left channel, red to the right.
Step 4
Select from both the "upper" and "lower" halves those in which all connections are intact. By combining them, collect the number of working pairs of headphones that you get.
Step 5
Repair the defective halves of the earbuds, if desired. To open the plug, simply cut off the PVC sheath with pliers, under which you will find a frame made of harder plastic. Soldering pads are built into this frame. Remove the caps from the headphones themselves with a sharp knife and pull out the emitters from them, which also have soldering pads. When gluing the caps back after repairs, be sure to wait until the glue is completely dry before reinserting the earbuds into your ears. Use only safe adhesives.
