How to solder headphone wires to make them work?

Many users of smartphones, MP-3 players and other portable devices for playing music often experience their headphones breaking. This happens because thin wires are regularly subject to deformation due to twisting, rewinding or other bending that occurs every time the accessory is put into a pocket or bag. On expensive large headphones, you can replace the cable, as this is provided for by the design of the gadget, but this solution is not suitable for inexpensive accessories. However, there is no need to rush into buying new devices - there are several simple ways to fix headphones if the wire breaks. Most users can do the repair work themselves at home.

5, 6 or more wires

Depending on the implementation option, there may be 5 or more wires inside the cable from the headset.
Up to 10! Be that as it may, they always try to make the signal wire from the microphone in its own “ground” braid. In short, if you gutted your cable and it looks something like this:

or even this: no one will immediately tell you how to properly solder the plug to such headphones. There can only be one piece of advice here: take a tester and test all the wires until you determine where the right ear is and where the left is. The remaining wires are to the microphone.

Determine by color which wires may be common and connect them all together. Solder all signal signals according to the connector pinout (see pictures above).

Then test the headphones and microphone. If something is wrong, look for the reason. No one will really tell you anything here; proceed using the scientific dildo method.

Good luck!

Connecting wires and cables using couplings

If the cable to be connected is in the ground, water or rain, then conventional methods of isolating the connection are not suitable. Even if you apply a layer of silicone sealant to the cable and compress it with heat-shrink tubing, this will not guarantee tightness. Therefore, it is necessary to use special couplings.

Couplings are available in plastic and metal casings, poured and heat-shrinkable, high-voltage and low-voltage, regular and small-sized. The choice of coupling depends on the specific operating conditions and the presence or absence of mechanical loads.

Connecting wires and cables is one of the most important points in electrical installation. Therefore, all methods of connecting electrical wires must ensure good contact. Poor contact or poor insulation may result in short circuit and fire.

How to Determine Headphone Jack Size

Most users can determine the diameter of a connector or plug visually, since the vast majority of devices are equipped with a 3.5 mm jack. If the diameter of the plug in your device is smaller than usual, then it is a 2.5 mm jack; if you are using professional equipment or a musical instrument with a connector of increased diameter, it is probably a 6.35 mm connector. It will not be difficult to distinguish a jack from Lightning and US.

Inexperienced users should use a measuring device, such as a caliper, although a school ruler will show a difference of 1 mm.

Headphone repair: useful tips

An alternative method that allows combining varnish removal and tinning involves the use of fine-grained types of sanding paper. Small rosin is placed on the working side of the paper. On this piece we place the ends of the wires to be tinning. Apply solder to the tip of the heated soldering iron tool and press down the cable. After melting the rosin and heating the wire, using a little force, pull it out from under the soldering iron. With such manipulations, abrasive grains remove heated and slightly softened insulation residues. And at the same moment tinning is carried out. By repeating this procedure, the ends of the wire are evenly coated and are ready for soldering.

We carefully disassemble part of the body of the cut off headphones using a knife along the contour of the assembly lines. At the end of the heated soldering tip we place the contact section of the connection of the old wire

When the solder softens, it is necessary to remove the wires.

We pass the cables with the stripped ends into the holes of the headphone housings. Here it is necessary to provide for tying a safety knot. Thanks to it, the contacts remain intact with a slight jerk of the wires; it bears the entire main load.

As a result, all that remains is to solder the end, ready for soldering, to its contact place in the housing under the earphone. When performing these steps, it is necessary to take into account the correct connection of the contact according to its color markings.

Soldering headphone wires is quite simple if you use wooden clothespins as auxiliary tools. They will play a kind of role as mini-clamps, which will allow for a strong fixation of the workpiece, and will also save your fingers from unexpected injuries such as burns.

Also, similar actions should be followed in case of repairing the wire at the junction of the plug, step by step:

cable cutting;
stripping of insulation;
tinning of mounting ends;
disassembling the plug housing (if necessary);
soldering the ends in place;
carrying out reassembly.

By learning how to solder headphones, you can restore the devices’ functionality without any problems and save a lot of money on it. Don't be afraid, experiment and listen to your favorite music using refurbished headphones with your own hands.

What does the sound in headphones consist of?

Many cores are channels, each of which outputs the content of a specific frequency band to the master bus in the speaker (the one that is inserted into the ear). Thus, it is clear that damage to at least one of these veins completely eliminates the frequency range for which it is responsible. Why can't you hear this?

It's about two things:

stereo;
the rest of the veins.

If one frequency is missing on the left, it will be heard on the right. In addition, when the frequency at which the channel was output loses it, the residual signal is transmitted through other wires. Thus, the overall load on the sound increases. It starts clipping and overloading. Why do cheap headphones for 30 rubles sound so bad? The number of people living there is minimal and they don’t listen to modern music at all. What can I say, even radio broadcasts are difficult to broadcast.

As for grounding, everything is simpler there. As long as at least one core is functioning, it exists. But as soon as she rubs it, the sound will change.

It is this factor that is the reason that the contacts are tinned and not exposed using a stationery knife.

A good example of frequency loss is an audio splitter. A device that divides one headphone input into two. Not only the volume sags, but also the frequency range. The sound stops pumping, it becomes quiet and flat, and the dynamics disappear. All for the same reason. The number of cores remained the same, but the number of outputs doubled.

Additionally about the colors of wires in headphones

How to properly solder wires to a headphone plug is out of the question if you are not familiar with the colors of wires in headphones and their meaning (for example, do you know what the green wire is responsible for?)

A different number of wires may come to the headphone plug:

2 wires (for mono headphones);
3 wires (for mono or stereo headphones depending on the connection diagram);
4 wires (for stereo headphones);
5 or 6 wires (for stereo headset with microphone).

2 wires

I don’t think anyone needs to explain how to repair a headphone plug if they only have two wires. It is basically impossible to confuse anything here.

3 wires

There are always two wires coming from each ear - plus and minus, but sometimes the manufacturer combines the minuses of both speakers together and it turns out that only three wires come to the plug. To make it clearer, here is a soldering diagram for a headphone plug:

This picture explains even more clearly where to solder the wires to the headphone plug:

Most often, the wires are coated with varnish of different colors:

red
- right channel;
green, blue or white
wire - left channel;
colorless varnish
- common wire (ground).

Of course, there are no strict standards and colors may vary. Here's what it looks like in real life:

Let's see how to properly solder a wire to the headphones (3 wires):

4 wires

If your plug has 4 wires, then there may be options.

Option one:

you have ordinary headphones without a microphone and without buttons (the plug has only 3 contacts). Then these four wires are simply two pairs of wires from each of the speakers. Their disadvantages are the same color (copper), and their advantages are different (usually blue and red or green and red):

In this case, common wires (those of the same color) are connected together and soldered to the common contact of the plug. You should immediately understand how to solder 4 wires from the headphones to the plug from the figure:

Here's how to solder headphones to such a jack:

Option two:

you have a full-fledged headset (i.e. headphones with a microphone) and the plug has 4 contacts. Then, most likely, these four wires are one wire from each speaker, one signal wire from the microphone, and one common wire for all.

Schematically, this can be indicated as follows:

And here's how to make a plug on the headphones (correct soldering of headphones when there are 4 wires):

Most often, a microphone wire only looks like one wire, but in reality it is two wires: a thin wire in white PVC insulation completely wrapped in enameled copper wire (in colorless enamel). Something like this: And in this case it would be more correct to say that the headphones have not 4 wires, but all 5.

5, 6 or more wires

Depending on the implementation option, there may be 5 or more wires inside the cable from the headset. Up to 10! Be that as it may, they always try to make the signal wire from the microphone in its own “ground” braid.

In short, if you gutted your cable and it looks something like this:

Determine by color which wires may be common and connect them all together. Solder all signal signals according to the connector pinout (see pictures above).

Then test the headphones and microphone. If something is wrong, look for the reason. No one will really tell you anything here; proceed using the scientific dildo method.

Various headphone breakdowns are a very common problem, especially if this device is used actively and not for listening to music at home. Most often, in-ear headphones break - earbuds and vacuum plugs, since they are usually used outside the home - for example, during active sports.

Typically, the likelihood of failure is influenced by the following factors:

factory defects are the most common problem with cheap headphones;
improper use - connecting the headphones to the wrong sound source can cause the speaker to break, and if you carry the sound source in your jeans or trousers pocket, the plug will be subject to constant pressure and sooner or later it will break.

If the headphones stop working, they may need to be taken apart. Of course, this is not always possible - for example, the most difficult thing to disassemble are earbuds and plugs that have a monolithic body. In addition, after disassembling these headphones, you may need new replacement parts.

In addition to the headphone body itself, you can disassemble the plug that connects to the sound source. But before you begin any operation, you should make sure that it is even necessary by diagnosing the breakdown.

Solder the wire to the plug

In almost all cases, a common malfunction of accessories is the cable breaking in the plug area. Most often, nothing else can be done other than replacing the connector and soldering it. But don’t think that this procedure is quite difficult and you can’t do it. Almost anyone can do it. The main thing is to understand the wires, of which there may be several, and each one needs to be soldered in its designated place.

General principles

If you have problems with the plug, it is best to replace it with a new one, but you can try to make an old one. How to solder headphones with a plug - see further instructions.

Step back a little from the damaged area and cut off the plug completely. See below if you want to solder the old plug.
Take a utility knife and cut open the old plug along the seam to remove the rubberized surface. You will get its inside, where there will be contacts with remnants of wires on the plastic surface. Remember the position of the cables or take a photo/write down so you don't forget, because you will be soldering them in the same way. They are usually arranged by color.
Lightly strip the wires so that they look smooth, intact, and make soldering easier. Connect two common colorless cables by twisting them together.
Tin the ends of the cables. To make this process easy, you can lightly burn them with a lighter or matches, or remove the enamel coating with a knife. After this, you can easily tin them, and the soldering process will be easier.
If you can’t buy a plug or don’t want to go out and buy one, a regular pen will help you. Unscrew the very tip (the small ones, where the side of the rod you write with is located), this will be your plug body, which you will solder to the connector.
Cut the desired piece of heat shrink. You can choose the dimensions yourself to match the body of your plug. This part will protect the place where you solder the plug and where it connects to the cable from new tears.
Now let's move on to soldering. Determine the required locations for the ends of the wires in accordance with how they were originally sealed.
Make sure the accessory is ready to play. A multimeter will help here. Listen to each ear in turn. You should listen to rustling noises and various sounds. You can try inserting the plug into the phone and turning on music. But do it carefully.
After you are sure that the device is working correctly, secure the heat shrink (with a hairdryer, matches, lighter - any device you have at hand).

Continuity of wires

If the cable breaks, as well as in other cases, it is necessary to determine which wires are connected to the headphones, microphone and control buttons.

There are certain wire color standards that manufacturers adhere to, although they may be violated:

colorless (copper) – common wire;
red – right channel;
green – left channel;
blue - microphone;
other colors – control panel (buttons, or “rocker”).

Depending on the model, the wires to the microphone and control panel can be combined or separate, and in different elements of the headphones there can be one or more common wires. A shielded wire can go to the microphone.

How to connect wires by crimping

Another way to connect wires is crimping. This is a method in which a copper or aluminum sleeve is placed on the wires or cables to be connected, and then crimped with a special crimper. For thin sleeves, a manual crimper is used, and for thick ones, a hydraulic one is used. This method can even connect copper and aluminum wires, which is unacceptable with a bolted connection.

To connect using this method, the cable is stripped to a length greater than the length of the sleeve, so that after putting on the sleeve, the wire sticks out 10–15 mm. If thin conductors are connected by crimping, then twisting can be done first. If the cable has a large cross-section, then, on the contrary, in the stripped areas it is necessary to align the wire, fold all the cables together and give them a round shape. Depending on local conditions, the cables can be folded with the ends in one direction or in the opposite direction. This does not affect the reliability of the connection.

A sleeve is tightly placed on the prepared cables or, when laid in opposite directions, the wires are inserted into the sleeve from both sides. If there is still free space in the sleeve, it is filled with pieces of copper or aluminum wire. And if the cables do not fit in the sleeve, then a few wires (5–7%) can be cut off with side cutters. If you do not have a sleeve of the required size, you can take a cable lug by sawing off a flat part from it.

The sleeve is pressed 2–3 times along its length. The crimping points should not be located at the edges of the sleeve. It is necessary to retreat 7–10 mm from them so as not to crush the wire during crimping.

The advantage of this method is that it allows you to connect wires of different sections and from different materials, which is difficult with other connection methods.

DIY headphone repair

Most often, small-sized models used in mobile communication devices fail. These are miniature capsules connected to a smartphone with a thin wire. The sound device includes the following elements:

Sound emitters
Volume control
Connecting wires
Plug

You can repair headphones for your phone at home. The most common defect is broken connecting wires. They are very thin and have poor insulation. In order to determine the break point, you need to connect the headphones to an audio device, turn on a piece of music and sequentially “wash” the entire connecting wire with your hands. At the break point, the sound will appear and disappear. Most often, a wire break occurs at the junction of the wire with structural elements. This is the wire entry into the plug body, the volume control input and output, the connection point to the left and right capsules, and the wire splitter into two channels. In addition to breaks at the connection points, the wire can be damaged by pets.

To repair headphones, it is not necessary to change the entire wire. It is necessary to localize the location of the contact failure, disassemble the specific unit and restore the integrity of the connection using soldering. How to fix headphones if the contact at the plug is broken.

The connector (plug) can be linear or “L”-shaped. In any case, it will not be possible to save the plastic cap, since it is not dismountable. It should be carefully cut with a sharp blade. Usually the contact failure is located at the plug itself. Before removing the wire, you need to remember the colors of the conductors soldered to the plug contacts. The wire is cut, the insulation is removed, and the individual conductors are stripped for soldering. The conductors in the veins are very thin and consist of a bundle of wires together with threads made of synthetic material. Each copper wire is varnished. It is difficult to remove the insulating coating with a sharp cutting tool without skill, so it is easier to burn the varnish in the flame of a lighter.

Then the cleaned ends of the wire need to be tinned. For this, rosin, an alcohol solution of rosin or a paste-like flux are used. Using a heated soldering iron, apply a small amount of solder to the flux-treated wire. Remnants of factory soldering are removed from the plug contacts. Before soldering, a small piece of heat-shrink tubing is placed on the wire. It will replace the cut plug housing. The prepared and tinned wires are soldered to the corresponding contacts of the connector. A heat-shrinkable tube is placed on the plug and heated with a household hairdryer or lighter. This way you can repair the headphones at home.

What to do if the headphones break at the sound capsule. To eliminate the defect, you need to open the case. Miniature sound emitters consist of two parts, which are connected with glue, since the manufacturer does not intend to disassemble the devices. A scalpel or office knife is used to separate the body. If the wire breaks off near the capsule itself, then it is enough to clean the broken end, tin it and solder it in place. Sometimes you have to cut the plastic case to find the break point. Breaks at the volume control and splitter are eliminated in the same way. You can repair headphones when the wire breaks in the middle. The torn section is cut out, and the conductors are stripped, twisted and connected by soldering. The main thing is not to confuse the colors, but to put insulating tubes on the twists. A heat-shrinkable tube is put on the place where the wire is spliced, which then heats up and tightly grips the joint.

If the wire is damaged along its entire length, then it can be replaced, but it is easier to purchase new devices.

Identification of the rupture zone

To repair damaged headphones, you first need to find a break, and this can be done by probing or using a multimeter . Probing the cable to detect a breakdown is the easiest way. You need to connect the headphones to the sound source, start the music and begin to carefully bend the wire in the direction from the plug to the speakers, without missing a single centimeter. If in some place the music begins to be interrupted, a crackling sound or other noise appears - this is the place where the wire breaks.

Using a multimeter is a professional and more accurate way to detect cable damage. It is necessary to turn on the measuring device, set the sound diagnostic mode, and then connect the probes correctly: black to the COM connector, red to mA. Now you need to carefully make notches near the plug and the earphone itself, and then install the probes in them. If the device beeps, this means that the wire is intact, and the problem needs to be looked for elsewhere. If the multimeter is silent, you need to make a cut in the middle, and then check both halves of the cable one by one. Where the wire is intact, the device will beep. The tester is silent on the damaged part of the cable. In this area you also need to find the middle and make a cut again. In this way, you should check the cable until there remains a faulty section a couple of centimeters in size.

Important! The best way to reconnect damaged wires is to use a soldering iron. If the user does not have such a device or experience working with it, it is allowed to twist or connect the torn wires with solder or solder paste.

How to disassemble Earpods anyway?

Unlike the previous Earpods model (on the fourth iPhone), the second one is much better in quality. For example, the headset in the area of the microphone and volume control is protected both at the top and bottom from kinks by thickening. Opening this part of the wire is not difficult: just use a pick or something thin that can be pryed, for example, with a scalpel.

To partially open the funnel, remove the layer of glue using a scalpel. What we see after opening:

paper membrane;
postings;
voice coil.

The case also contains one very important component - a magnet, which ensures sound quality.

How to connect electrical wires with lugs

Another way is to use tips. The tip looks like a piece of tube, cut and turned flat on one side. A hole for a bolt is drilled in the flat part. The lugs allow you to connect cables of any diameter in any combination. If it is necessary to connect a copper cable to an aluminum cable, special lugs are used, in which one part is copper and the other is aluminum. It is also possible to place a washer, brass or tinned copper, between the tips.

The ferrule is pressed onto the cable using a crimper, similar to how wires are connected using crimping.

Thermal tube instead of tape

Using tape is not entirely kosher. Therefore, I propose to improve the technology a little, again without a soldering iron.

You will have to buy a heat-shrinkable tube, also known as thermal casing, at an electronics store or hardware store. This is such a clever tube that can shrink in diameter by at least half when heated. This miracle costs about $0.1 - $0.5 per meter.

We will need two thermal tubes with different diameters: 1-2 mm for the first and 4-5 mm for the second.

We put pieces of thin thermal tube on our twists. We cut the pieces with one and a half margin.

Now you need to heat the thermo tube. Usually I did this with a soldering iron, but we agreed that I didn’t have one, and the story was about how to fix headphones without a soldering iron, so I had to get out.

The method turned out to be quite effective and the thermo-tubes shrank. You can also use any other heater or put them in boiling water like Easter eggs. In principle, people can do it with a regular hairdryer.

While the thermotube is still hot, you can further flatten it with your fingers, then it will slightly stick together inside.

This thermo-tube must subsequently be put on the joint and also compressed with the heat of the lamp. In general, you can squeeze lighters on fire, but you can accidentally set fire to excess.

I used a piece 8-10 cm long. To strengthen the structure, the end of the thermal tube was put directly on the elastic band of the connector.

How to do without a soldering iron

If you don't have a soldering iron, then this is not critical. The described technique is perfect for ordinary headphones without a microphone and control buttons. Unfortunately, it is useless if the cord breaks near the speaker.

List of what you need:

knife;
lighter;
scotch;
working AUX cable.

Cut off a part of the cable with a connector no shorter than 7 cm, remove the rubber braid with a knife, exposing about 2 cm. You can clean the varnish using sandpaper or a lighter. In order not to damage the wiring, the fire must be extinguished periodically. The carbon deposits can be easily removed with your fingers, but you need to wait until it cools down.

Make an incision a few centimeters above the plug to ensure that the erased area is removed.

Twist all paired wires as tightly as possible. If there are more than three of them, then the two extra ones (responsible for the microphone) can be hidden or cut off, and the sound input will stop working. Sometimes the colors match, but it’s better to check the combination by inserting the connector into the socket of the player with music turned on.

For insulation, use electrical tape, treating each individual pair. After this, they are connected and wrapped in 3-5 layers. You can use wide tape (painting tape will also work) or thin thermal tubes.

Repair of a headset with a sound boost function and a microphone

Headphones equipped with a microphone do not differ fundamentally from the standard system. However, to know how to make them work, you need to understand some of the nuances of their operation. The causes of problems in such a headset, as in conventional headphones, can be broken wires, failed plugs or broken headphone membranes that require replacement.

Sometimes exotic breakdowns occur in the form of stretched wires. This situation is not typical, since in ordinary life wires are more likely to be crushed than stretched. In this case, the damaged section of the cable can be easily felt - a strong thinning of the core will be noticeable in this section. You can fix the damage using your usual soldering iron. Remove the insulation and protective varnish from the wire. Experts say that this can be done with a candle or lighter. After this, their ends are tinned and reliably soldered - the DIY headphone repair is complete.

Repairing broken headphone wires is easier than it seems, but it will take some time. Stock up on all the necessary materials so as not to interrupt the process and not leave exposed parts unattended. Be careful with small wires, because they are very easy to damage with wire cutters or a knife.

Regardless of the cost of the headphones, they may become unusable as a result of improper handling or force majeure circumstances. Sometimes you need to carry out repairs right away, and in most cases without having the necessary tools at hand. To do this, it is enough to know how to repair headphones without a soldering iron.

Connecting wires by soldering

Once a damaged section of the cable has been identified, it is recommended to cut it out completely, rather than looking specifically for the break point. Next, you need to remove the outer insulation from the wire by about one and a half to two centimeters. Under it you will find several wires (from three to five, if the headphones have a microphone), which also need to be cleaned of protective insulation, if present. These steps will need to be repeated for the second piece of cable.

Important! Heat shrink tubing will be used to insulate the repaired cable. A piece of the required length should be placed on one of the cable sections before connecting them. Also, small pieces of heat-shrinkable tubing of a smaller diameter must be placed on each core.

Next, you need to firmly connect the wires of the same color, and then apply a layer of solder on top with a soldering iron. After the solder has cooled, you need to put pieces of heat shrink on the exposed wires and heat them with a hairdryer so that the tube shrinks and wraps them tightly. This is necessary so that the wires do not touch each other and do not cause a short circuit . Next, the insulated pieces of cable need to be assembled together, a piece of heat shrink of a larger diameter must be put on them and heated. This way they will not dangle, and the repair site itself will look beautiful.

Cable break near the plug

If one ear does not work, and diagnostics of the break point showed that the cable at the plug or the element itself is damaged, it is recommended to replace it with a new one. To do this, you first need to purchase another plug, and then cut off the old one along with a couple of centimeters of wire. Next, the new plug is unscrewed, and the insulation and braiding are removed from the cable by about 1.5-2 cm.

Important! The grounding conductor (usually yellow or two-colored) should be soldered to the copper sleeve, and the remaining two wires to the plug contacts. Solder correctly by first cleaning the contacts with fine sandpaper to ensure the best connection.

After completing the work, you need to assemble the plug, and it is important to make sure that the wires are not connected to each other. Otherwise, the headphones will not work. Read more about this in our article “how to repair a headphone plug.”

Break near the speaker

If, upon inspection of the accessories, it is discovered that they are torn at the speaker, you will need to disassemble the earphone to repair it. It is usually connected with latches, screws, or glue.

Advice! If the case is connected with glue, you need to clamp the device in a vice and apply pressure - the crack will go along the place of gluing.

The wire inside is almost always tied in a knot to prevent it from being pulled out during careless movement. It needs to be cut, the insulation removed, a safety knot made again and soldered to the contact with a soldering iron. After the repair, you need to reassemble the earphone. Other reasons why one earphone does not work are in our material.

Problem Definition

So, a TRS type connector is intended for connecting devices, for example, headphones and a player, with each other.

Next we need to tin our wires. Be that as it may, they always try to make the signal wire from the microphone in its own “ground” braid. A different number of wires can be connected to one plug - it depends on the class of headphones: mono - 2 wires, it’s difficult to confuse something here; stereo and mono - three wiring and different connection diagrams; stereo headsets - 4 pcs.

In the photo below, the clamp is marked with a red circle on the unsoldered connector; The cable clamp is marked in red. For greater reliability, we insulate the contacts with electrical tape, and at maximum proximity to them we recommend tying a knot on the cable.

If you connect to an MP3 player to listen to music, you can use the balance to check how each channel works. If they are ringing with stereo headphones, then this is the control panel, and the microphone and both wires are connected to the microphone output; 7 cores Additionally about the colors of wires in headphones. How to properly solder wires to a headphone plug is out of the question if you are not familiar with the colors of wires in headphones and their meaning. So, for example, do you know what the green wire is responsible for?

Here the plug has 4 types of contacts: one from each speaker, one for the microphone, and there is room left for soldering a common wire or ground. You need to solder in full accordance with the colors of the wires in the headphones; we remember where which color was soldered or look for our piece of paper where everything is written down: Don’t forget to first attach the housing and heat shrink to the wire! Here's what it looks like in real life: Let's see how to properly solder a wire to headphones 3 wires: 4 wires If your plug has 4 wires, then there may be options. Let's make sure everything works.

On the Internet, of course, you can find a method on how to connect the wires in headphones without a soldering iron, but this cannot be compared with the reliability of soldering. Headphones with a microphone are connected via 4 wires. If after work there is still no sound, even after checking all the wires for solder, then the damage to the wires may be near the speaker itself.

We twist the screen of the right and left channels together; as mentioned above, it can be three wires, two of which are channels, and one is a common screen, in this case we simply remove the insulating varnish from them; we disassemble the new connector, do not forget to thread the stereo headphone wires through its base, as shown in the photo, otherwise you will have to redo everything; An important point: the wire must be threaded into the base of the connector; we proceed to soldering the wires to the connector. Otherwise, you can call the wires using an ohmmeter multimeter, an electronic tester, or determine by selection the simplest option - insert the plug into the player and apply the wires to it one by one until the correct combination is found

Also pay attention to the 3rd plate, which is located on the back of the headphones. As a result of this, we can state that the problem lies precisely in the plug. However, the procedure carried out using a soldering iron guarantees better quality work.

However, the procedure carried out using a soldering iron guarantees better quality work.

As you can see, in two out of three cases the problem is solvable. It is for such situations that special adapters have been developed. To solder them to the plug, we need to strip them of the insulating varnish by about a mm, but no more than is required for soldering to the contacts, so that when soldering we do not accidentally short-circuit the exposed wires.

Connecting wires without a soldering iron

If the user wants to do without a soldering iron to repair torn headphones, he can use solder paste, solder, or make a reliable twist.

Solder

You can fasten wires with solder without the help of a soldering iron. For this you need a small metal container. You need to put a small amount of solder in it and also add rosin. Now you should light the stove, place the dishes on it and melt its contents.

Next, you need to lower wires of the same color one by one into the solder and run them along a wooden block so that the substance is distributed evenly . You can perform the same steps and remove excess solder using a simple rag. Next, the wires are connected together, after which you need to wait until the material hardens. After this, the exposed sections of the wire must be insulated using heat shrink tubing or electrical tape.

In the same way, you can solder a wire if it breaks at the plug or near the earphone. In this case, you need to pour crushed solder and a little rosin onto a flat surface (contacts), and then heat it so that the substance melts. After this, the material is evenly distributed with any convenient object and the prepared wire with applied solder is applied to it.

Another convenient way to solder two wires together without a soldering iron is to use foil. The action diagram is as follows. It is necessary to remove the top braid from the cable, and then remove the insulation from the contacts (usually varnish with thread). Next, you need to cut strips from the foil along the width of the exposed wires. They are used to make grooves into which contacts twisted in pairs are placed separately. Solder and rosin are poured on top of them and distributed evenly along the surface. Now you need to wrap the foil tightly around the wire so that there are no gaps, and heat it until the solder melts. Next, the foil is removed, and the wires are tightly compressed with pliers, but this must be done carefully so as not to damage them. Excess solder can be easily removed with fine sandpaper.

Solder paste

Solder paste is more often used than regular solder to repair broken wires without a soldering iron. This process is faster and easier than working with solder and rosin.

On a note! It is inconvenient to work with a solid substance, but the paste is much easier to apply to the surface being treated. You can buy it at the store or make it yourself.

To repair headphone wires, you need to coat the exposed contacts with paste, connect them together and heat them over an open fire or in any other way. With this connection, soldering occurs deep between the wires, so its strength is significantly higher than when using solid solder.

Twist

Twisting the cable is the simplest solution. You need to take two identical wires from 2 to 4 cm long, connect them together and braid them, after which you need to put a heat-shrink tube on top or wrap electrical tape . The connection should be very strong, but do not tug the cable too much during operation. If everything is done correctly, the headphones will last for a long time.

How to strengthen the headphone wire

The easiest way is to make additional winding, especially in the place where the wires are connected to the plug. This is where wire chafing most often occurs. Soviet headphones were made from dense copper veins, which were difficult to cut. Modern cheap headphones have extremely thin wires that can be cut.

On expensive models, you can notice reinforced fiber at the bend of the wires or a thicker elastic layer. Such protection will ensure smooth deformation of the wires and prevent them from being torn off.

Historical reference

The first models of studio headphones had reinforced wires. Producers and sound engineers could not afford to miss any moment during the performance, so they wrapped the wires with an additional layer of insulation. They did the same with microphones. If you look at photos of pop music concerts (especially rock music) of the late 20th century, you will notice a solid layer of winding on the microphones. The modern music industry is moving to a wireless option and soon there will simply be no need to repair plugs.

How to connect telephone wires

The telephone wire is also quite fragile. It is easy to tear and damage. Of course, it needs to be connected. This is not so difficult to do.

If the wires used for the telephone connection have the same colors, then you first need to find out which wire is which.

This can be done using a tester. Dialing is its standard function. It is quite simple to produce it.

After the wires have been found, they can begin to be connected to each other. This procedure can be done by connecting by soldering.

It is this method that is rational in this case. If you don’t want to solder wires, you can purchase an additional adapter for a telephone cable.

Tips in the article “How to properly connect electrical wires?” Here.

It can also be used to make a connection. However, it is worth remembering that in this case, special crimps for conductors must be used for the connection. Fortunately, these days it’s quite easy to find them.

Of course, you will need two special terminal blocks in this case, which will be connected from different sides of the adapter.

All electrical engineering, since the time of Faraday, uses wires. And for as many years as wires have been used, electricians have been faced with the problem of connecting them. This article explains what methods there are for connecting conductors, and the advantages and disadvantages of these methods.

How to solder headphones with a microphone

To properly repair headphones with a microphone, you need to know the connection circuit and the purpose of the jack pins. A typical diagram of a microphone plug and button in a stereo headset is shown in the picture below.

For most manufacturers of simple headsets, the microphone should be soldered as in the picture.

How does a four-pin jack work?

has the same device as . Coaxial design and separation by plastic bushings with standard sizes into 4 wires is present on all TRRS plugs. The pinout of 4-wire plugs differs by manufacturer. There's a lot of people here. To correctly replace the plug, look at the pinout of the minijacks in the picture.

The picture shows the following symbols: M - microphone, G - common contact, R - right channel, L - left channel. Now it’s clear that soldering headphones is not an easy task. The wiring diagram of the plug greatly depends on the brand of the headset.

Soldering wires for garlands and headphones without a soldering iron

On the radio market, almost all garlands and most headphones are made in China. Chinese manufacturers, in their struggle to save materials, use wires in their products that are so thin that it is quite difficult to solder them to each other with a regular soldering iron.

Therefore, when performing repair work, it is better to do without a soldering iron at all. The stripped ends of the wires are twisted into a tight connection. Take a pointed rod of copper wire ø 1-2 mm. The twist is coated with solder paste. The rod is heated with a candle at a distance of 3 cm from the tip of the tip. Simultaneously with this tip, twisting is carried out, obtaining high-quality soldering. This is one of the best methods on how to solder thin wires without a soldering iron.

There is another ingenious way to solder thin wires. An ordinary paper clip is used as a soldering rod. It is bent so that it is convenient to solder, holding the rod with pliers.

Second soldering method

The second method, which tells you how to solder headphones by tinning the wires with sandpaper:

The sandpaper grains should not be particularly coarse. You will need a small piece of the material itself.
Apply a little rosin to the material, then place the wiring on it.
Warm it up properly with a soldering iron and pull it out. The varnish on the wire will begin to soften.
Repeat the pulling procedure until the insulation is completely scraped off.
After repairs, insulate the area with heat shrink or electrical tape.

Some people remove the insulation using a lighter, then remove carbon deposits with alcohol and flux.

Direct soldering process

Repairing headphones comes down to restoring contact in damaged wires.

For this you will need:

soldering iron;
solder;
rosin;
stationery or construction knife.

To ensure complete confidence in eliminating the problem area, a piece of cable approximately 1-3 cm long is cut from the earphone.

To remove the protective insulating casing, you need to scrape off one-half inch (1.25 cm) of the outer braid using wire cutters or a utility knife.

Using a construction knife, the outer insulation of the cable is stripped. Inside there are two wires, marked with different colors. Most often, the left channel is marked with red, the right channel with green, and the common channel is marked with either blue or yellow. Sometimes the common channel is bare copper wire.

In a section of about 0.5 cm from the end of the wire, it is necessary to remove the insulation.

Depending on the material, you can remove it in several ways:

The polymer insulation is carefully removed using a knife so as not to damage the conductive material.
Varnish and paint are removed by burning with a soldering iron or mechanically using a knife or fine sandpaper.

The stripped ends of the internal cores are tinned with solder. The soldering iron is plugged in and left for the time required to heat it up. Then take a small piece of solder with the tip of the soldering iron. The stripped end of the wire is installed on rosin. The soldering iron tip distributes the molten solder evenly over the entire cleaned surface. The wires are ready for soldering.

To do this, you must additionally take a tablet of acetylsalicylic acid (aspirin) or any aspirin-containing medicine. Even expired tablets will do. So, before you run outside, you need to look into your home first aid kit.

Standard plugs

Before we begin the repair, let's look at the most common types of headphone jacks, as well as their connection diagram. This will help us decide how to solder the headphone wires if the cable has 4 wires (headset with microphone) or 3 wires.

Below is a classic diagram for connecting headphones connected to each other by a common ground. In quality devices such as Koss Porta Pro, Philips, Sony, Sennheiser, etc. a separate shielded wire is used for each channel; in more budget implementations, there may be a common shield for two channels.

Connecting headphones to a standard plug

For headphones with a microphone, the plug has an additional contact pad; a diagram of such a connection is shown below.

Diagram for connecting headphones with a microphone to a standard plug

Note that many manufacturers of mobile devices can use non-standard connectors; we will consider this topic at the end of the article.

Lots of wires

After cutting off the headphone jack, remove the insulation from the wire. We do everything the same as with the AUX cable. But there is a small catch.

There are clearly more wires in the headset than three - there are five of them. Two wires are for the microphone, and three for the headphones. That's what we need.

A frayed gold wire (ground) was wound over a thin white wire - a microphone one. We twist it into a separate wire and clean all the wiring from the varnish.

Now we are faced with the impossible task of twisting the necessary wires together. It's really simple! Three AUX wires need to be screwed to three headphone wires.

In my case, it turned out that the colors of the wires matched. What if not?

Wiring diagrams for wires with more than two cores

Users often wonder whether it is possible to repair headphones of a more complex design when there are more wires inside? A different number of wires may be suitable for one plug - this depends on the class of headphones:

mono - 2 wires, it’s difficult to confuse anything here;
stereo and mono - three wiring and different connection diagrams;
stereo headsets - 4 pcs.;
headsets or headphones with microphone - 5-6 pcs.

Now we will tell you in more detail about each class, except the first.

Three cores

Each earphone must have two wires in the same braid or in different ones - this is a plus and a minus. Sometimes at the end, when connecting to a plug, designers combine the negative ones into one harness and get 3 pieces at the output. To make it clear to all users, we provide a detailed wiring diagram for the plug, where you can see exactly where the wires need to be soldered according to their color design.

Four wires

There are two different options here.

Ordinary headphones without a microphone and control buttons. 4 wires are connected to the plug: a minus from each copper-colored speaker and a plus (blue with red or green with red). For convenience, the negatives are twisted into one bundle and the result is three wires that need to be soldered to their specific places.
Headset with microphone. Here the plug has 4 types of contacts: one from each speaker, one for the microphone, and there is room left for soldering a common wire or ground. Schematically, such soldering looks like this:

5 cores or more

Different types of headsets of the latest class may have from 5 to 10 separate veins, so it will be much more difficult to navigate. The signal wire from the microphone is always braided in one color, and the rest come in all sorts of shades. No specialist can tell you exactly which wire should be soldered where. How to replace the wire from the plug on the headphones in this case? The only method that works here is this: we check each vein with a multimeter to determine whether it goes to the left or right speaker, then we find the common ones and combine them into one flagellum.

You need to solder it to the plug according to the diagrams that we showed, or find a separate diagram on the Internet that is suitable for your case.

Repair your headset or headphones for your mobile phone using this method and save money from your home budget.

How to connect an internet cable

Many people now have access to the Internet in their homes. Everyone knows that the wires of the so-called twisted pair are quite easy to break, since they are quite thin. In this case, they will need to be connected to each other. In fact, the technology is not that complicated.

If a twisted pair wire breaks, you should immediately select all the wires by color. This is done quite easily. There are no wires of the same color in a bundle.

After all the wires have been selected, you need to connect them. Of course, you can crimp them and install a new adapter plug.

However, you can simply solder all the wires together according to color. In this case, it is worth using special cambrics to isolate the conductors from each other.

They are sold today in almost any electrical store. They are first put on the conductor, and then soldering is done. After its completion, the cambric is pulled over the junction of the conductors.

Soldering with speaker

Sometimes the contact breaks inside the speaker. In such cases, repairs begin with disassembling the headphones. They try not to shake or tug the device to avoid tearing off the board, inspect the structure and find the damaged area. All broken wires will have to be soldered.

If the cable breaks at the “input” of the earphone, and due to the structure of the case it is impossible to pull it out, then it is better to make a cut at the base. Cut the cord 20 mm from the end of the adapter. It is necessary to remove 80 mm of the thickest insulating layer. Do the same with the internal insulation, but be careful not to touch the wires. Next, the ends are cleaned and tinned according to the standard procedure.

Insert the cord into the housing and unsolder the old wires one by one, soldering new ones in the same places. After soldering is completed, the earphone is assembled and immediately tested for functionality. If the sound is of poor quality or completely absent, then disassemble the case and re-inspect the contacts. The possibility of damage not related to the speakers cannot be ruled out.

How to connect electrical wires by soldering

Connecting electrical wires by soldering is very reliable. You can solder untwisted wires, but such soldering will be fragile due to the fact that the solder is a very soft metal. In addition, it is very difficult to lay two conductors parallel to each other, especially when suspended. And if you solder on some kind of base, the rosin will stick the soldering area to it.

A layer of rosin is applied to the pre-tinned and twisted conductors with a soldering iron. If another flux is used, it is applied in the appropriate manner. The power of the soldering iron is selected based on the cross-section of the wire - from 15 W when soldering headphones to 100 W when soldering twisted wires with a cross-section of 2.5 mm². After applying the flux, tin is applied to the twist with a soldering iron and heated until the solder completely melts and flows into the twist.

After the soldering has cooled, it is insulated with electrical tape or a piece of heat-shrinkable tubing is put on it and heated with a hairdryer, lighter or soldering iron. When using a lighter or soldering iron, be careful not to overheat the heat shrink.

This method reliably connects wires, but is only suitable for thin wires, no more than 0.5 mm², or flexible ones up to 2.5 mm².
