How to solder the plug to the headphones: step by step instructions
Quite often happens in the life of music lovers such a situation that your favorite headphones stop working. The most common problem is mechanical damage to the cable near the plug. This happens for various reasons: sharply pulled the connector out of the socket, caught something or squeezed lightning. And just from time to time. How to fix the situation and bring the headphones back to life? Let's see how to solder the plug to the headphones.
What you need to do first
Before proceeding with self-repair, it is necessary to determine the nature of the damage and the possibility of replacing only one connector. It also happens that, in addition to this, cable replacement is required.
It is also worth assessing the financial side of the issue: the purchase of the necessary tool can result in the cost of work in the workshop, or even the replacement of headphones with similar ones. Answers to these questions will tell you how to get started, how to solder the 3.5 plug to the headphones and whether it is necessary.
Most of the stores sell collapsible plugs, which consist of two parts: the connector itself and the case into which the first one is screwed. They also differ in quality and material of manufacture. Undoubtedly, for higher-quality headphones, you need to choose a more expensive connector, so that interference from a cheap "jack" does not spoil the joy of owning good headphones.
For this operation, we need:
- The headphones themselves or headset with a faulty or torn connector.
- A new connector that you will install.
- Low-power soldering iron with a thin sting.
- Solder, rosin and flux.
- Sharp knife or pliers.
This is the minimum set of tools with which you can begin to work. A good tool is the key to success, since it will be easier to solder the plug to the headphones using it.
How to replace the headphone plug
In order to correctly perform the operation to restore the headphone performance, you need to know how to solder the headphone wires to the plug, which ones go where, and follow the instructions. This is done in a few simple steps.
Step one - preparation of wires for subsequent soldering.Before you begin, you need to prepare everything by removing the insulation from the wires. This will simplify further work. This can be done with a sharp knife or pliers.
There should be three wires: red, black (possibly white, blue or green) and a shield braid (it can also be insulated, usually transparent). Isolation of red and black wires should not be completely removed, leaving 2–3 mm each, so that later there is no contact between them.
The second step is to prepare the connector for subsequent soldering. The spare part bought in shop should be disassembled on the making elements. It should slightly scratch the place of future soldering, as this will allow to solder the plug to the headphones better.
After this, the wires must be soldered with solder, trying not to touch the points to which you will not be soldered. Places in the connector and so little, and the extra "snot" of solder only complicate further soldering.
The third step is the soldering itself. The first thing to do is to thread the wire into the connector body. To do it after this will not work, you have to redo it. Before soldering it is worth paying attention to which wire went to the tip.This should be the left channel, that is, the black wire. The first thing soldered "land", and then the channels - left and right.
Step four - isolating and assembling the connector. In order that contacts did not close and did not spoil headphones, it is worth insulating a connector. The easiest way to do this is tape. To do this, it is necessary to carefully, in a thin layer, wrap the plug, checking whether the case sits in place. If done correctly, the connector will assemble, and the headphones will work.
How to replace the headset plug
Headphones with a microphone - a headset - have a slightly different design than simple headphones, but not so different as to not cope with this. So how to solder the plug to the headphones with a microphone?
The headset has only one wire more than regular headphones. This wire goes to the microphone. Pinout connector can vary greatly depending on the manufacturer of the headset, but there are two main points:
- CTIA, where pinout from the tip looks like a left-right-common-microphone.
- OMTP, where everything is a little different - left-right-microphone-common.
When soldering, if there is such a need, it can be altered from one standard to another by interchanging the two extreme wires.
What not to do
The most serious mistake made by all is an extra hurry, as it is not so easy to solder the plug to the headphones correctly. Working with soldering is quite painstaking and accurate, the speed will lead to errors that can seriously affect the performance, or even completely spoil the gadget. The main errors of self-repair are as follows:
- Poor soldering, which is why after a while the headphones or headset stop working.
- Poor isolation of contacts, due to which headphones also do not work.
- Buying a poor-quality connector, which is why it is not possible to do well.
- Do not use a plug with a short circuit. It can kill the speakers, which will only lead to a replacement.
- Incorrect marking of the length of the wires will not allow to assemble the connector.
Tips and secrets
- The tester in ohmmeter mode will tell you how to solder the plug to the headphones, if the colors are very different from the usual ones, and you forgot which channel you were in.
- The left channel of any headphones - the very end of the plug. The second one is always right.
- If you can not buy a connector, you can save the previous one, and the body can be made from a pen cap or epoxy resin.
- When soldering a cheap plug, insert a spring from the same pen into it. Speaking at the end of the connector, it will save the wire from kinking.
- For more convenient work with the connector, you can make a simple holder. To do this, you need to drill a hole in the tree and insert a plug into it.
As you can see, with the observance of simple rules and following the instructions, the work of replacing the headphone jack is not so difficult. With the availability of tools and proper skill, it can be done in half an hour. But then the joy of the fact that you yourself repaired your favorite headphones can not be compared with anything.
