Headset repair. How to solder headphones: general recommendations and special cases Headphone input pinout

There are times when you have to do the pinout of headphones. For example, the device does not work well, and the wire needs to be unsoldered to find the reason.

Connector types

1. Micro jack 2.5 mm. Suitable for portable and pocket devices (players, phones).
2. Mini jack 3.5. Mounted for household items (TV, computer).
3. Big jack 6.35. This type of connector is used for special equipment. For example: powerful acoustic amplifiers or musical instruments. But they can also be used for smaller devices (microphones, metal detectors).

Jack also has several categories, depending on the number of outputs. It happens:

1. Two-pin. Transmits unbalanced signals. For example, mono signals for headphones or audio recording on microphones.
2. Three-pin. Can transmit both symmetrical and unbalanced signals. In the latter, contacts numbered 2 and 3 are connected using a jumper.
3. Four-pin. Transmits both video and audio signals. They can transmit both at the same time. Such ports are made in modern models of smartphones, players or tablets.
4. Five-position. Very rare. Created by Sony for the Xperia Z smartphone. Allows two microphones to function simultaneously. One of them is responsible for noise reduction.

Nests are also divided into two types:

1. Regular. Made for a specific type of plug.
2. Switchable. Able to adapt to all types of plugs by switching their position.

How to ring wires

Wires going to various parts of the device are ringed using a tester. First of all, we are looking for those that go to the speakers:

1. We clean the ends. In some types of models, the wire that goes to the microphone is shielded, and the screen is capable of performing the functions of the corresponding cable.
2. We put on headphones. After connecting the tester, we will hear a crackling sound from the speakers. If sound comes from only one, the tester is not connected correctly. It probably only contacts the speaker where the sound is coming from. It is necessary to connect the tester to the common wire. If sound is coming from both headphones, the tester is contacting both channels.

Our actions will differ depending on the number of wires:

1. If there are 4 wires in the cable, the one that remains should be connected to the microphone and volume control through the control panel.
2. If there are five, there are two left that need to be checked. If they can communicate with each other, but cannot communicate with the speakers, they need to be connected to a microphone. And if others call, we solder them to the terminal together.
3. If there are seven wires, the rest are connected in pairs to the microphone with the headset button. They are soldered depending on the colors, both to the microphone and to the common terminal.

Pinout diagrams for headphones with microphone

The pinout diagram will differ depending on the headphone model. Most often, plugs consist of two, three or four parts, each of which is responsible for transmitting certain signals. For example:

1. A two-piece plug has one common wire. Most often used for a microphone.
2. With three parts consists of three wires (right, left and common). Used for headphones. The right channel is responsible for the right earphone, the left for the left, and the common one for connecting the contacts (one cable goes to the plug, but approximately halfway through the length it separates into two, one for each earphone).
3. With four parts. Here the plug is divided into two types. The first is a four-wire design for modern versions of phones, players and tablets. Channels right, left, general and microphone. The second type is for outdated versions of Nokia phones. Channels – right, left, general and additional signal.

In modern phones, the plug consists of four parts (responsible for the headphones and microphone). The pinout is identical for the following models:

1. Apple.
2. Samsung.
3. Lenovo.

If you look at the plug visually, it consists of some segments. Each is responsible for a specific channel. For example:

1. The very first segment, the edge of the plug, is responsible for the left.
2. The second segment is behind the right.
3. The last one, the longest, is responsible for the general one. It is closest to the wire.

Headphone wiring

The most common plug version is called jack (in English Mini Jack) version 3.5. But in addition to it there may be jack 2.5, mikroUSB and miniUSB. We will look at how to solder the jack wires.

If the headphones are standard, the cable should have three wires. The wires are numbered from tip to cable:

1. Left.
2. Right.
3. General channel.

But in some types, 4 wires are installed instead of 3 (they are paired). If you come across such headphones, wires of the same color are considered pairs and are soldered together.

Reference! Soldering the wires to the jack plug is very simple. The ring that is closest to the cable is considered the common channel. And the rest are left and right. With conventional wiring, the right channel is connected to the middle one, and the left channel to the plug.

The wires must be soldered to the appropriate places. You can find these places using a tester or visually.

Jack 2.5 is similar to this version. The only difference is the connector. The desoldering process will be the same.

Mini and MicroUSB are used to connect to some types of mobile phones, players and other small devices. The wiring for Mini and Micro is the same. There are 5 pins inside. Cables are soldered to them. They are numbered from left to right. The common one is soldered to the first pin, the right channel to the third, and the left channel to the fourth.

Broken connector

Headphones break very often. Most often, the problem is not in the speakers or the wires, but in the plug, or pins needed to make contact with the wires. If the contacts are stuck, they need to be soldered. But broken plugs will have to be completely replaced.

It is easy to determine that the cause of the breakdown is in the headphones. You need to connect another, working device. If the new ones don't work either, the reason is in the port. For repairs you will have to contact a service center.

If there are problems with contacts, you can determine the breakdown in the following ways:

1. One of the speakers does not work. For example, left or right.
2. The sound is very low or unclear.
3. There is a noise.

Try to touch the place where the wire enters the plug. If, when you touch, you see the slightest changes in sound quality (it has become clearer or louder, or vice versa, the quality has dropped), you can be 99% sure that the reason is in the contacts. The cable needs to be unsoldered. Using a soldering iron, attach them.

If the plug is not working, the sound will not reach the speakers at all. Only a complete replacement of the plug will help here. We buy a new one and solder the wires to it. You can also contact a service center for repairs. But if there are constant breakdowns, the most profitable solution is to buy a new device.

In 2012, the developers got a bad start, and many (but not all!) began to speed up the pinout CTIA(Cellular Telephone Industries Association), also known as AHJ (American Headset Jack):

• Tip - Left Channel
• Ring 1 - Right channel
• Ring 2 (Ring2) - General (Gnd)
• Base (Sleeve) - Microphone (Mic)

In fact, in these wiring connections the microphone and ground contacts are swapped. If you connect a headset with an inappropriate pinout to the device (for example, connect a classic Nokia one to a Samsung Galaxy), the sound in the headphones will be noticeably muffled, and it is not a fact that the microphone will work (in the worst case, the device will not detect the headphones at all).

To determine the headset standard, measure the resistance between the tip and the base of the TRRS plug with the remote control button released and pressed.

OMTP- when pressing the button resistance does not change and is about 30 Ohms (headphone resistance).
CTIA- the resistance is noticeably more than 100 Ohms, and when you press the button it drops to the same 30 Ohms.

What to do?

To ensure compatibility of devices and headsets of various standards, adapters have been created " CTIA and OMTP". The beauty is that this adapter converts both CTIA to OMTP and OMTP to CTIA. It's nice that some manufacturers carefully equip their headsets with such adapters. As an example, I can cite the headsets Ergo VM-901, Jabra RHYTHM, Philips SHE3595.

But our compatriot is not like that! Many of us would prefer to pick up a soldering iron and remake the headset ourselves once and for all. Detailed instructions for re-soldering are published in the article "".

1. Reworking the remote control has its drawbacks. The fact is that in decent headsets the microphone core (or even the entire cord) is made of shielded wire, and the functions of the screen are performed by the common wire (GND). Of course, after reworking the headset or using an adapter, the common wire becomes the microphone wire, and the microphone wire becomes the common wire. Thus, the common wire ceases to serve as a screen and the consumer qualities of such a headset are somewhat reduced. Of course, a headset whose cord is made of ordinary wire cannot be damaged by such alterations.

When you open the remote control, you will most likely find several GND wires coming from the plug and soldered to different points on the board. For example, a general screen and a microphone wire screen. Or a left channel common and a right channel common. Having unsoldered the common wires from the board, be sure to connect the free points with jumpers. And only then solder the wire that used to be a microphone to any of these points. After that, it remains to solder one of the former GND wires to where the former microphone wire was just soldered.

Method No. 1

2. Resoldering the plug is a more competent way to remake it.

Method No. 2

I must point out two unpleasant nuances:

1. There have been cases with iPhone headsets when neither the adapter nor the soldering helped, and the microphone did not work. I even do not know why.
2. No modification, no adapter will make it work - volume and rewind.

Samsung: OMTP is supported by models up to and including 2010, although I can’t vouch for flip phones from the mid-2000s. And 2011 is a borderline year for Samsung, some models are wired according to the new standard, some - according to the old one. Cm. .

You will laugh, but...

The variety of pinouts is not limited to two standards - CTIA and OMTP. An extended overview of headset pinouts is given in the article "".

And that's not so bad. Alas, the tragedy of incompatibility between gadget and headset is not limited to pinouts alone. There are a lot of headsets on the market with circuit bells and whistles, “thanks to” which even a compatible (in terms of pinout) headset may not be recognized by your smartphone. In this case, the headset will at best serve as headphones.

If a gadget (for example, some kind of androphone) do not support multi-button headset, then no adapter and no soldering of this headset (for example, from an iPhone) will allow you to enjoy the convenience of the “Rewind”, “Volume”, etc. buttons. In this sense, redesigning simple one-button headsets, which have only a microphone, a button and a capacitor between pins 3 and 4, leaves strong hope.

As a result of constant bending of the wire near the 3.5″ Jack plug, noise may appear in the headphones when the connection of the plug to the wire is moved, or even the sound on one of the headphones will disappear completely. Sometimes the common wire breaks, then the sound is distorted: high and mid frequencies disappear almost completely. This happens because the right and left amplifiers of the phone are turned on in antiphase and their output signals almost completely cancel each other out.
It also happens that the stereo effect simply disappears. Or there is no sound in the ears, but the microphone works, or vice versa. And sometimes, due to a break in the microphone wire, the control buttons on the headset cord stop working along with the microphone.

So, a TRS type connector is intended for connecting devices, for example, headphones and a player, with each other. The device consists of a plug (plug) and a socket (jack). Often this connector simply breaks at the point where the wires enter the connector itself. Because of this, either the right or left earphone or both at once may not work for you. Moreover, sometimes extraneous noise appears due to wire breaks in the jack 3.5 connector itself.

In general, it is worth noting that the abbreviation TRS itself comes from the English words: tip (tip), ring (ring) and sleeve (sleeve). Among the Russian-speaking population, the concept has been established that “jacks” are the plug itself, so if you use the original name of the TRS connector in everyday life, many will not understand what we are talking about.

Plug types and applications

Depending on the diameter of the working surface, connectors are divided into:

1. Micro jack 2.5 mm. They are equipped with small portable devices such as phones, players, etc.
2. Mini jack 3.5. They are installed in household appliances: computers, TVs, etc. In addition, the pinout of jack 3.5 is extremely simple.
3. Big jack 6.35. Mainly used in professional equipment: electric musical instruments, powerful acoustic amplifiers, but can be built into budget equipment, such as karaoke microphones, metal detectors.

Based on the number of outputs (pin), jacks are divided into:

1. Two-pin ( T.S.). They transmit an asymmetrical signal, for example, a mono signal is sent to headphones or audio is recorded using a microphone.
2. Three-pin ( TRS). Using them, you can transmit both an asymmetrical signal, with pins 2 and 3 connected by a jumper, and a symmetrical one.
3. Four-pin ( TRRS). They can immediately transmit video and audio information. Modern phones, tablets, video players, etc. are mainly equipped with four-pin connectors.
4. Five position ( TRRRS). An uncommon connector used by Sony in the Xperia Z smartphone for the simultaneous operation of two microphones, one of which works for noise reduction. TRRS compatible.

There are also two types of sockets: regular, created for a specific type of plug, and with a switch - when the pin is inserted, the device switches from one position to another.

Very often there are situations when Chinese collapsible plugs, which were installed instead of a monolithic broken “jack,” do not completely fit into the sleeve or are poorly fixed. Such situations are possible when the diameters of the sleeve and plug do not match. Therefore, when choosing such a plug, it is advisable for you to check its outer diameter with a caliper along the entire working length.

How to find out if the connector is faulty

Insert working headphones into the jack and turn on the music. If music does not play in working headphones, your connector is broken. Also, if you hear a hissing sound when the plug moves, this means that the connector will soon completely fail.

Nowadays, the pinout of headphone wires with a microphone shown in the first picture below is mostly used everywhere, but there is also another one, which is mainly used on old phones and in phones from some manufacturers. They differ in that the microphone and ground contacts are swapped.

Four-wire plug

There are two different options here.

1. 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.
2. 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:

It should be noted that color marking may vary depending on the imagination of the manufacturer and is very arbitrary. The left channel wire can be green, white or blue. The right channel wire is always marked red. The common wire is copper (varnished or without insulation), but it can also be white if white is not used for the left channel.

Self-replacement of the 3.5 plug

We will need a knife, soldering iron, solder, rosin. Cut off 5-10 cm of wire from the plug, remove all the insulation from the plug, remember the sequence of wires by color (sometimes they are different). Strip the wires and solder them to the 3.5 mm jack. It is better to fill the soldering area with hot glue and compress it with heat shrink, so the connection will last much longer.

Quite often it happens on the headset broken wire, suitable for the plug - according to experts, this is the most common defect that occurs due to frequent kinks and various mechanical damage.

Inside the cable there are several very thin and delicate wires that can easily break from strong tension or jerking. Is it possible to repair a headphone plug on your own, and what is needed for this?

Preparing for work

To repair headphones yourself, we will need:

• non-conductive glue or epoxy resin;
• a special heat-shrinkable tube is an alternative to electrical tape;
• old fountain pen;
• tester (multimeter);
• soldering iron with a thin tip and all accompanying components (tin, rosin);
• side cutters;
• mounting knife;
• lighter.

It's better to use fabric glue if you can't find epoxy resin, which only needs a few drops.

Repair algorithm

You can repair a lot of things yourself - the main thing here is the desire and ability to work with various tools. Let's look at the whole process step by step.

Now we can see where the wires are soldered to the plug - we take a photo for memory, so as not to confuse anything later. However, there is standard wiring, coming from the headphones: copper (yellow) color - general, green - left earphone, red - right.

We remove the cut wire leading to the headphones from the varnish coating, clean and tin the ends of the wire, and connect the grounding of each channel together.

We check the plug for a short circuit, first removing any remaining tin. The channel layout is shown in the photo:

We take the old handle, disassemble it and use only the tip - from it we will make a new housing for the plug we disassembled.

Cut off with side cutters to the required length heat shrink tube, which, instead of electrical tape, will protect the wires from sharp bending at the very exit of the new plug.

We put the future housing on the wire, then the tube, and proceed to the final installation. How to solder wires so as not to mess anything up? There is a photograph taken earlier for this.

If the test result is positive, we put a tube over the soldering area and, using an open flame of a lighter, “squeeze” it so that it firmly grips the open part of the plug, as shown in the photo.

That's the whole process of how to fix headphones from a mobile phone or laptop headset.

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? One plug can accommodate a different number of wires - it depends on headphone class:

• 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.

There is no strict standard for coating with colored varnish. For example, the left channel wires can be blue, white or green.

Four wires

There are two different options here.

Important! At first glance, the microphone wire looks like one wire, but in fact there are two of them: a very thin wire in a PVC sheath is wrapped on top with a copper wire with colorless enamel for protection.

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.

Headphone wiring

If the wires come off the headphone plug, they are soldered back according to certain rules. This article describes what the wiring (pinout) of wires should be like.

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.

, Headphone pinout

How to ring wires

The wires going to different parts of the headphones can be tested using a tester. First of all, you need to find the ones going to the speakers:

• Strip all wire ends. In some models, the wire going to the microphone is shielded, where the screen plays the role of one of the wires.
• Put on headphones. A crackling sound will be heard in the speakers when connected to the tester. If it is in only one speaker, then the tester is connected to one of the channels and the common wire. If a crackling sound is heard in both speakers, then the tester is connected to two channels, without a common wire.

• With four wires in the cable, the remaining one is connected to the microphone and control panel.
• With five wires, if the remaining two communicate with each other and do not communicate with the speakers, they are connected to the microphone along with the control panel and the common terminal. If the remaining ones call with the others, then they are soldered together to the microphone terminal.
• With seven wires, the remaining four are connected in pairs to the microphone and buttons. They are soldered by color, to the common and microphone terminals.

DIY headphone repair

Headphone wiring

The most common plug is a 3.5 mini-jack. But besides it, a 2.5 jack is used, as well as miniUSB and mikroUSB.

Wiring for 2.5 and 3.5 jack plugs

There are only three wires in a regular headphone cable. A plug with this number of pins is also called TRS. The numbering goes from tip to cable:

2 - right channel;

Instead of three wires, there may be four (two pairs). In this case, one wire from each pair of the same color is considered common and soldered together.

The wiring on such a plug is very simple - the contact ring closest to the cable is common, the remaining ones are the right and left channels. In a standard wiring, the right channel is connected to the middle ring, and the left channel is connected to the end of the plug.

Solder the wires to the appropriate soldering spots. They can be determined visually or with a tester.

The 2.5 plug is designed similarly to the 3.5 and is no different from it except for its size. The wiring is the same on both plugs.

Wiring in miniUSB and miniUSB plugs

In some mobile phones, headphones with a microphone are connected via mini- and mikroUSB connectors. But you can also connect just headphones to these connectors, for example, to use such a mobile phone as an MP3 player.

The wiring in these connectors is the same. They have five pins to which wires are soldered. They are numbered from left to right when viewed from the side where the wires are connected, and the wires are soldered to 1 (common), 3 (right channel) and 4 (left channel).

Wiring in a headset - headphones with a microphone

In addition to regular headphones, which only have speakers, there are headphones with a built-in microphone and control buttons. The cable of such devices has a large number of wires - from four to seven.

Wiring in the 3.5 plug

These plugs have the technical name TRRS. There are two options for wiring these devices OMTP and CTIA. They differ in the connection of the microphone and the common wire, which connect to 3 and 4 wires.

If you connect the wrong type, the microphone will not work and the sound will be muffled.

Connecting a headset to mikro- and miniUSB plugs

In some phones, headphones are connected not to a 3.5 plug, but to a mikro- or miniUSB connector. There is also a standard when connecting to the terminals of such plugs. They are counted from left to right when viewed from the side where the wires are connected:

2. microphone, as well as control buttons;

Headphone adapter

If you have headphones whose plug does not fit into the device, you can make an adapter.

For this you need:

• a plug that can be connected to the device;
• female connector into which headphones are connected;
• a piece of three- or four-core cable to connect the plug and connector.

Information! You can use a cable from an unnecessary mouse or keyboard.

The manufacturing procedure is as follows:

1. cut a piece 10cm long from the cable;

2. cut it on both sides to a length of 15mm;

3. strip the ends of the wires by 5mm;

4. tin the stripped ends;

5. tin the output of the plug and connector;

6. place the non-separable parts of the connector on the cable;

7. solder the wires to the connector;

8. write down the wiring;

9. depending on the design of the connector, secure the cable inside with a clamp or by tying a knot on it;

10. assemble the structure;

11. Repeat steps 6-10 for the plug, soldering the wires according to its wiring.

Important! Only neutral flux can be used for soldering. The acid will destroy the wire or cause a short in the plug.

Instead of a detachable 3.5 plug, you can take a non-separable one, with a piece of cable of the required length. This will not work with USB connectors - different pins are used to connect headphones and a computer.

In addition to standard connectors, there are plugs used only in certain phone models. These are the 10- and 20-pin connectors of Samsung phones and some others. Headphone wiring for these models can be found on the Internet.

All mechanisms break sooner or later, and it’s good if the wire from the headphones breaks far from the jack (plug). But what if the plug comes off, but the wire is intact? Completely change the headset? What if the headphones are expensive? There is an exit! After reading the article, the reader will learn how to independently repair headphones in any condition, and it does not matter whether he knows how to solder or not.

Why do headphones break?

The main reason is “factory settings”. Each model is designed for a specific service life. Good headphones are not the ones that don’t break, they are the ones that people buy all the time. Therefore, if your favorite couple breaks down, don't blame yourself. These are all the tricks of greedy manufacturers and monster engineers who profit from unhappy customers.

Expensive headphones last longer, but they also break. Their price is determined not only by quality. Premium technology costs what consumers are willing to pay for it.

Headphone wire colors

• Most headphones have only two pairs of wires - for the left and right channels.
• If there are three wires in the headphones - left, right and common - there is a master controller that regulates the volume of both channels.
• If there are 4 pairs there is a left, a right and a ground for each of them.
• The five wires are left, right, ground for each, and a microphone channel.

Of course, there are other options (for example, headphones with a microphone and one speaker), but the vast majority of models are designed exactly as described above.

The wires are usually double, that is, the wire with the “ground” contains an additional layer of insulation.

The left channel is green by default, and the right channel is red.

In some headphone models, the plug is marked (L (left), R (right), S (stereo), M (microphone). The contacts for ground are not additionally marked. If there are no contact markings, you need to take a closer look to see if there is a plug on the body remnants of plastic winding of the corresponding color.It is extremely rare that the wires are completely torn out.

What does the sound in headphones consist of?

The set of 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.

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.

You can also treat the wire with a layer of paint or varnish, which will save the headphones from hypothermia. You may notice that in the cold season, the headphones harden and the chance of damaging the wires is much greater than in the summer. Both too low and too high temperatures can cause damage to the accessory.

ADVICE! Don't let the wire get tangled on its own. Confuse him on purpose! Roll it up so that there are no kinks. In this state, it will not twist or tie itself into a knot.

Shorten it. The longer the wire, the greater the chance that it will break or fray at some point. The short wire will not get tangled and will provide comfort and ease of use.

Another good and creative way to strengthen and reinforce the wire is to braid it with sewing threads. This method will not only protect the headphones, but also make them unique by painting them with unusual designs or patterns. In the cold season, they will be protected from frost and will definitely not crack.

How to connect wires to a plug?

Let us immediately note that the wires can simply be twisted, but to obtain a truly strong and high-quality connection, the wires must be soldered. In fact, there is nothing complicated in the procedure.

Tools and consumables:

• soldering iron (any one will do);
• solder and rosin;
• clean connector (3.5 mm jack);
• insulating tape;
• scissors;
• stationery knife for paper.

REFERENCE! You need to pay attention to the number of segments on the plug. It must match the amount on the old ones, otherwise part of the frequency range will be cut out.

1. Carefully cut the wire crosswise so that both wires are the same length.
2. Cut it lengthwise, dividing it into two wires. Do not damage the winding of the pair, as it is an additional protective layer and protects the accessory from damage.
3. Each wire must be tinned in aspirin (acetylsalicylic acid). There is no need to strip with a knife, as the thin wires will be damaged and sooner or later break
4. Attach the wires to the corresponding contacts on the plug.
5. Solder using a small amount of tin. It is better if they do not touch each other, so as not to provoke a frequency conflict.
6. Insulate the layer with electrical tape.
7. Do the same for other contacts.
8. Wrap the resulting connection with electrical tape in several layers and put on a reinforced layer. If there is none, you can use ordinary aluminum or copper wire, and then wrap it with electrical tape again.

If everything is done correctly, the headphones will sound as before. If you hear subsidence in the volume/depth/brightness of the sound, one of the points is performed incorrectly or the contact is partially or completely broken.

You should not use cheap solder, since the resistance of tin will not allow you to transmit the entire frequency range. The sound will be cut off at the top and no equalizer will correct this.

• When buying cheap headphones, expect a year of service life. Almost no one has them for longer.
• If you are repairing an expensive pair, you will need a good soldering iron with a thin tip so as not to fill everything around with solder.
• Copper, silver, gold - all this is clearly better than tin. Good sound requires good materials.
• Reinforcement of headphones greatly extends their service life.
• You can tin your contacts not only with aspirin. There are many ways. If the reader is repairing expensive studio headphones, you can clean them with a knife, since the thickness of the copper will allow this to be done.

Conclusion

We hope that this article has dotted all the i's, told the reader how the headset works, and suggested how to fix it yourself. Let's go over the main points of the article:

• you can practice using cheap unnecessary headphones instead of ruining an expensive pair;
• cheap solder = cheap and low-quality sound;
• Absolutely all headphones break, but the difference is in service life.

Try twisting the contacts before soldering. If the sound passes through, feel free to fix it; if not, reconsider the connection diagram. Take care of your favorite headphones, don’t throw them anywhere, don’t leave them in the cold, and they will last a long time without failure. And if a problem has already happened, our instructions will definitely help you fix everything in a matter of minutes.

The pin-type TRS connector (the name is derived from the English abbreviation tip, ring, sleeve) is often used in various audio devices. It has several design options, the 3.5 mm jack (also known as a mini-jack) is aimed primarily at headphones of initial or medium quality playback, and can also be used in microphone circuits, radios, players and various multimedia gadgets. This type of connector is also quite popular in mobile phones.

General view of the 3.5 jack connector

Design features 3.5 jack

TRS has three pins of standardized sizes, allowing stereo signals to be reproduced. On the pin part of the connector plug, the diameter of which is 3.5 mm, there are three contact areas, which are located sequentially one after another and are separated by insulating washers.

Signals from the left and right channels of stereophonic broadcasting are supplied to the head of the tip and the ring that follows it; the ring closest to the body is intended to connect the ground common to these channels. An additional groove is made on the end part of the tip, which gives it a clearly recognizable characteristic shape. This design allows you to fix the plug in working condition due to the corresponding design of the spring-loaded contact of the socket part of the connector.

Cable for TRS connector

A homemade connecting cord is used in cases where the length of the purchased product is not enough. The functions of the cable can be performed by almost any two-wire cable with a braided screen. Both twisted pair and untwisted wires are suitable for signal transmission.

Layout of cable wires according to contacts and their connection

Due to the small number of working contacts 3.5 jack pinout not very complicated. Standard wiring is shown in the figure below.

The 3.5 mm TRS jack finds limited use in professional devices, which are characterized by a balanced connection used to improve quality. This situation changes a little and takes the following form:

In both cases, soldering is used for connection. Its implementation is facilitated by the presence of holes for inserting cores on the channel contacts of the cable side. The ground contact is connected under the clamp. The cores are pre-serviced.
