Recently my Samsung earphones began giving trouble with distortion of or complete loss of sound in one then both earbuds. As they were of high quality it seemed a shame to just throw them away.
Below details the process in how I went about repairing them. Please note other models of equipment may very. Please check and test all equipment and ensure disconnection from mains supplies when testing finished product.
After cutting off the jack and stripping back the white outer sheath there are 3 cables inside ( Red, Green, and Black )both surrounded by a copper sheath. Carefully unwrap the sheath from the cables and combine into one wire.
As the cables are so small I suggest using a lighter to remove the coloured sheath surrounding them. Having completed that you should be left with something like this;
After preparing the cable the next step is verifying the pin output of the jack. I purchased mine from Kenable Ltd on eBay ( as seen in the photo below). When we disassemble the jack we find the contacts upon which we will be connecting our wires to.The jack will look something like the image depicted below.
Upon some research it is noted that the following is the pin output of the jack. The colour coding for the corresponding pins are;
- Left – Green
- Right – Red
- Ground – Copper
- Mic – Black
Next step is referred to as “belling out” the pins. This is a simple continuity test to establish corresponding input and output pins. The result of this test brought about this pin configuration;
After confirming the above your wiring should look like below
The finished and tested product. The clear sheath is an included part of the jack assembly and provides an extra layer of protection.
