Introduction
Headphone jacks are frequently subjected to wear through their normal usage. Instead of purchasing a new pair of headphones, which can sometimes have a hefty cost, replacing the connector is often a cheaper choice.
The use of a soldering iron is required in order to complete this repair. Since the wires used in headphones are often very small, this repair is only recommended for individuals with decent amount of experience in soldering.
Extra precautions should be taken while using the soldering iron, they are extremely hot and you will be working in very small spaces. The use of an Electrician's Helping Hand tool is highly recommended.
What you need
-
-
Cut the headphone cable near the old headphone jack. Leave some cable attached to the jack.
-
-
-
Cut open the outer insulation of the cable connected to the old jack to expose the internal wires.
-
-
-
Turn on the multimeter and set it to measure resistance.
-
Select a wire and touch one of the multimeter leads to the soldered tip.
-
Touch the other multimeter lead to each of the segments on the headphone jack until the multimeter indicates that the wire is connected.
-
Repeat the process for each wire.
-

-
Select a wire and apply a small amount of solder to the tip of the wire.
-
Repeat this for every wire.

-
Position a wire to the corresponding connection point on the jack.
-
Carefully apply a small amount of solder to hold the wire in place.
