DIY phone headset repair

In detail: do-it-yourself phone headset repair from a real master for the site my.housecope.com.

This article provides an example of repairing the Nokia WH-205 headset with visual illustrations. This method is suitable for repairing any wired headset or mobile phone headphones.

Very often, owners of mobile phones are faced with the problem of failure of a wired headset (headphones). However, there may be no sound from the headphones or the microphone may not work. As a rule, a person buys a new headset or gives an old one for repair. Why spend money when you can repair your headset yourself? In this article, we will answer the question of how to repair any wired headset or headphones yourself.

Let's take a look at an illustrative example of repairing the Nokia WH-205 headset. The main reason for the failure of the headset is wire damage or wire breakage at the soldering point in the microphone unit or to the plug. First, we inspect the headset.

In this case, the wires in the microphone unit are soldered normally. Next, we inspect the wire for visible damage. If the headphones work normally, the music does not disappear, and the microphone is faulty, then the wire is damaged in the area from the plug to the microphone. In the event of a malfunction of one or two headphones, the place of damage may be along the entire length of the wire.

As a rule, wire damage occurs as a result of stretching it. That is, the suspected place of damage can be detected by visual inspection of the wire. In this case, you should pay attention to changes in the thickness, color of the wire or other minor flaws. If the wire is torn as a result of stretching, then in the place of damage it differs in color, and is also slightly thinner than in other areas. If a damaged area is found, we proceed to the next stage - elimination of the damage.

To do this, we cut the wire at the place of damage and clean both ends. You can use a razor blade for this purpose by making a shallow cut around the wire. In this case, you should act carefully, as the conductor may be damaged by the blade.

After the wire is stripped, it is necessary to clean the conductors from the varnish. To do this, it is enough to bring the conductor to the fire for a split second.

Peeled conductor ends

After that, we put on a wire a small piece of a heat-shrinkable tube, which will later be put on at the junction of the conductors.

Heat shrink tubing on wire

Then you can go directly to the soldering of the conductors. When the conductors are soldered, it is necessary to insulate them from each other with small pieces of electrical tape. Then we put on a heat-shrinkable tube and heat it to the required temperature.

Very often the wire is damaged near the plug. If the wire is damaged a little further than the plug, then you can try to solder it. Then, as in the previous case, it is necessary to insulate the conductors and put a heat-shrink tube on them.

An approximate diagram of a headset on a 55A07A microcircuit is given below. All elements are assembled on a small printed circuit board, on which, in addition to the details, the buttons and the microphone are located. The 55A07A-X microcircuit provides identification of the headset when it is connected to a mobile phone, transmitting a special code pulse sequence through the ACI circuit. Similarly, it sends a message to the mobile phone about pressing the headset button. The supply voltage goes to the microcircuit from the phone.

Headset contact wire colors:

MIC + - yellow
MIC- - black
L + - blue
L- - red / blue
R + - brown
R- - golden / blue
Serial - golden
VOUT - red
GND - green

The loss of sound in one or both headphones or the fact that the interlocutor does not hear the words spoken in front of the microphone are most often to blame for broken wires in the connecting cable. They occur where there are frequent bends in the cable near the connector, headset housing, or headphones. Broken wires near the headset body are easily repairable. It is necessary to cut off and remove part of the wire between the breakage point and the contact pad on the board. Damaged headphones can be replaced with any suitable one. The wires of new phones are cut to the desired length and soldered to the contact pads of the printed circuit board instead of the faulty ones. For additional fixing of the wires inside the headset case, you need to use hot melt glue. In this case, after dialing the headphones, a break in the winding of the mini-speaker itself was noticed.Therefore, the only repair option is to solder a pair of headphones from one headset to another. The top cover must be removed. We pry with a screwdriver from the side of the wire going to the phone, first from one side, then from the other. Remove the cover and button. All further work on repairing the headset's performance is illustrated in the photos below.

After replacing the headphones and wires, we assemble the case and carry out tests - the headset works like new.

In the everyday life of a modern person, headphones are an indispensable attribute that allows you to enjoy listening to your favorite music and audiobooks anywhere and anytime. Unfortunately, this gadget does not last forever and is prone to breakage. In such a situation, you have to think about whether it is possible to repair the headphones with your own hands, or whether it is better to buy new ones. It is recommended not to rush to throw away the old ones, since broken ones, in most cases, can be repaired at home. How to fix the headphones yourself, and will be discussed in this article.Headphones are a fairly simple device, so all faults can be listed literally on the fingers. Frequent reasons why the headphones stopped working are the following:

breakage of the plug;

defective headphone cord;

the volume control is out of order.

If the headphones are broken, the first thing to do is to pay attention to junction of the plug with the cable... Often the cause of the breakdown lies in this very place. Due to frequent bends, the cable cores break, so the signal does not pass to one "ear" of the gadget or to both at once... Also, the microphone may not work.It is quite easy to detect a breakdown. It is necessary, with the gadget turned on, to try to bend the cable in the place of the alleged breakdown in different directions. If at the same time a sound appears or a crackle is heard, it means that one of the wires of the wire is interrupted. What to do if a problematic spot is found on the cable?To repair your headphones, do the following.

Cut off the plug from the cable.

To repair the plug will be used the inside of the old with a slight modification. To remove this part, you need to cut the plastic shell using a clerical knife, as shown in the figure below.

After cutting the plastic, pull out the insides of the plug. You will see contacts to which several thin wires of different colors are soldered. In the same way, you can disassemble headphones from an iPhone.

Video (click to play).

Memorize or sketch on paper to which pin, what color the wire was connected to. The pictures below show standard wiring diagrams cable cores. The color of the conductors may differ in different models, in this case, green is the left channel, red is the right channel, and copper (without insulation) is common.

If you need to repair headphones with a microphone, which are connected with one plug (usually there are 2 plugs on the cable), then the wiring diagram will be as in the figure below.

Next, you need to free the inner cores of the cable from the outer (general) insulation.

The procedure for replacing the plug is the same for all types of headsets, for example, such as: headphones Beats By Dr, Sennheiser (Senheiser) HD 215, Razer Kraken (Kraken) Pro, as well as, for headphones Steelseries Siberia v2, Audio-technica ATH-ES7 and headphones Defender.

How do I repair my headphones if the headset cord is faulty? You can try to find fracture site internal cable veins, probing and bending all its sections while the gadget is running. If you hear a crack or sound during the test, mark this place with a marker. Further, in the place of the break, the cable is cut and stripped. After that, the ends of thin conductors must be soldered, observing the color, and insulated.

If the break point is not found, then the entire cord will need to be replaced.... In the following example, the repair of vacuum headphones will be shown.

Before disassembling broken vacuum headphones, you need to purchase a new cable - you can order it online.
Using a clerical knife, carefully disassemble (separate) the glued phone gadget into 2 parts.
After opening, you will see the soldering points to which you need to solder the new cable.Thus, you can repair the headsets Beats (Bits) by Dr. Dre, Sony, Audio Technica Ath-CKR10.
In the same way, Iphone headphones are repaired. But when disassembling apple headphones, you should be careful and write down or sketch the location of the wires. They can be multi-colored.

Large gadgets, such as, for example, Philips headphones or Sven headphones for a computer, differ from plug-in ones only in the size of the speaker (membrane in small gadgets). Difficulties can arise when trying to get to the speaker in order to solder the wires.

Different manufacturers of headsets have different methods of opening them. These can be latches that are difficult to find or hidden screws hidden under the soft “cushions” - ear pads. For example, the question often arises, how to disassemble the Sennheiser HD203 headphones?

Use a credit card or other flat object to pry out the ear cups securing clips.
After removing the soft pads, you will see 4 screws that need to be removed.
On the disassembled device, you will see contacts with wires soldered to them, which must be unsoldered and replaced with new ones.

When repairing Steelseries Siberia headphones, the ear cushions stay glue-based... You can remove them by gently prying with a screwdriver, after which you can find the fasteners. Some models use latches instead of screws, which can break with strong pressure. If they break, you will have to glue the gadget cups, after which they will become non-separable.

On the Razer Kraken headphones, the ear cushions are not glued and are easy to remove.

After detaching them, the fasteners can be found under the glued paper.

In the Audio-Technica M30 or ES7 headset, they are also worn on the rim of the gadget's cup. Phillips headphones are no exception.

By the way, the Audio-Technica ES7 headphones have hinges for rotating the ear cups. Therefore, if you, while repairing a gadget, disassemble it, then you need to be careful.

The Philips SHD 8600 headset is free from all the drawbacks associated with replacing the plug and cable, since it is a representative wireless devices.

How do I fix my headphones if I have problems with the volume control in the form of loss of sound or crackling? In this case, you can use graphite greaseto apply it to the resistive layer to re-establish contact. The headset should then function without issue.

If the headset continues to work poorly after lubrication, then the regulator must be replaced with a new one.

Thus, in most cases, before you run and buy a new headset, you can do it yourself. This requires a thin tip soldering iron and skills in handling it.

Headphones consist of a wire, a plug, and two speakers. Additionally, the headset is equipped with a microphone and volume control. Any of these elements fail over time. Before making repairs, you need to figure out how to disassemble the headphones so as not to break them completely. Image - DIY phone headset repair

Reveal the malfunction of the plug by crushing the incoming wire with your fingers. The headphones are connected to a mobile phone or computer, play a music file, and then proceed to diagnostics.

Typically, copper conductors break at the entrance to the rubber or plastic housing of the plug and inside it. If at times a sound appears in the speakers while the cable is being repaired, then the plug must be disassembled and repaired.

Do-it-yourself headphone repair

The plug restoration procedure consists of the following steps:

The plug is bite off with pliers from the headphone cable.

The purpose of the repair is to remove the metal part from the casing. The element is firmly soldered. Trying to keep the old casing is unwise. It is easier to cut along it with a sharp knife.

The metal part of the plug is carefully removed from the casing so that the contacts do not break off. The soldered wires should be kept as well. The color of the insulation makes it clearer where to solder the cores of the headphone cable.

In the event of a wire breakage from the contacts on the soldering itself, the standard circuit shown in the photo is used for connection. The color of the insulation in the headset cable differs from manufacturer to manufacturer. Most often, the common core is in black or yellow insulation. To be sure, it is better to ring the tester from the speakers to the place where the cable is cut.

Headphones can be equipped with a microphone. In such models, instead of three, four cores are hidden under the cable braid. The connection takes place according to a different scheme shown in the photo.

The cable cut from the plug is stripped. First, remove the main sheath and release the ends of the veins. The edges of the thin wires are cleaned with a sharp knife. It is enough to remove 5 mm of insulation length so that it is enough to solder the copper core to the contact of the plug.

The wires are twisted from thin veins, and all of them are covered with a protective varnish. This sputtering prevents soldering. The varnish is removed by scraping with a knife or burned with a fire from a lighter. The ends of pure copper veins must be tinned. The common wire will be connected on one contact, so it is immediately soldered together.

The new plug cover is made from the bottom cap of a ballpoint pen. The wire is inserted through the pen opening. The put-on cap is moved along the cable further from the soldering point.

After the cap, a piece of heat shrink tubing is put on the wire. The sleeve protects the wire from breaking near the new plug cover.

The conductors of the cable are soldered to the contacts of the plug. It is important not to forget that the wires match the color of the insulation. The performance is checked by calling the tester. It is easier to plug the plug into the socket of a mobile phone or computer.

If both earbuds are working properly, a heat-shrink tubing is placed over the pins of the plug. It is heated by a lighter fire. The tube will fit snugly around the pins of the plug. For reliability, you can squeeze with your fingers while the plastic is hot.

Finally, the inside of the cap is greased with epoxy. A little glue is applied to the heat shrink tubing. Slide the cap along the cable until the back of the plug is fully inserted into the stopper. After a day, the resin will harden and the headphones can be used.

The wire can break not only at the plug, but also near the speaker. To get to this part in vacuum headphones, do the following:

A seam is found on the body of the earphone. They are trying to make an incision on it with a sharp knife. The body is lightly pressed with pliers so that the seam comes apart.

When the case falls apart into two parts, the rear of the speaker with contacts will appear on the survey. The damaged cores are soldered off with a soldering iron, but first they mark the color of the insulation with a marker so as not to confuse the wires.

A damaged piece is cut off from the general cable of the headset. The conductors of a working wire are stripped, after which they are soldered to the speaker contacts, observing the marks of the insulation color.

The operation of the vacuum headset is checked by connecting it to a telephone or computer jack. If a non-intermittent high-quality sound comes from the speakers, the halves of the headphone housing are glued together.

The speakers in the large earbuds are hidden inside the case, the disassembly of which is complicated by hidden screws and latches. If all the fasteners are not identified, the plastic elements of the headset will simply break from the applied efforts of the hands. The methods for disassembling headphones from different manufacturers differ. For example, consider several popular models:

Disassemble the Sennheiser HD203 headset by removing the ear pads. Soft pads are held by snaps, which are easily detached with a plastic card.

There are four screws under the soft pads. They are unscrewed with a screwdriver.

The halves of the case are not glued together. After unscrewing the screws, the elements will easily separate into two parts.The speakers are fixed on the front panel, to the contacts of which you have to solder a new wire.

Headset manufacturer Steelseries Siberia glues soft pads. The ear pads are separated from the body with a screwdriver or knife. The fastening of the body halves in different models is used with screws or latches. In the second option, disassembly is not complete without breaking the locks. The assembly of the case with broken latches is carried out with glue. In the future, it will not be possible to disassemble a firmly glued earpiece.

Things are simpler with the soft pads in the Razer Kraken headphones. The ear cushions are simply put on without being fixed with glue or snaps. After removing the overlays, a paper sticker enters the view. Four screws are hidden under it.

For Philips and Audio-Technica headphones, the ear cushions are similarly not secured with anything. The overlays are simply put on the rim of the cup.

Headphones for a computer are produced with a volume control and a microphone. The mobile phone headset is equipped with a button to turn on and off the conversation. All of these elements are hidden in a small plastic case attached to a cord. To get to these elements, you will have to perform similar actions that are used when disassembling vacuum headphones. The body is glued together, and you can only divide it into two halves by cutting with a knife.

A malfunction of the volume control is determined by crackling in the speakers and poor sound. The problem lies in the variable resistor. The part consists of a slider moving along the resistive layer. You can extend the life of the resistor with graphite grease. Using a cotton swab, the paste is applied to the resistive layer.

The problem of the microphone is revealed by the deterioration in audibility experienced by the subscriber with whom the conversation is being conducted. The cause is often a blockage. The microphone is wiped with cotton wool or gauze soaked in alcohol. After repairing the resistor and microphone, the two halves of the case are glued together.

Disassembling headphones of any brand is easy. The main thing is to be careful. Broken plastic parts cannot be recovered.

Headphone repair: 7 frequent breakdowns

Headphones are an indispensable attribute of the everyday life of a modern person. Have your favorite headphones stopped working? You should not immediately throw them out, if you have a little time and a desire to save the budget for the purchase, you can carry out the repair yourself with your own hands. Most often, the breakdown is not serious, so do not rush to purchase a new product. Basically, if you have even a little understanding of the use of a soldering iron, solder, wire cutters and glue, then the work should pay off. Pay attention to the instructions for your headphones, maybe there is a description of your problem.

Today, in the hardware store, you can see a large number of stereo headphones, ranging from wireless, vacuum and ending the list of standard large computer devices. Each of them is arranged differently. What external designs are not being sold in modern markets. Almost everyone has one or more headphones. They are purchased for different purposes, for example, for home use or for long subway rides, they can be both cheap and expensive, but they all have one big drawback, they break. A familiar situation, the wire is frayed and one earpiece becomes silent, instead of the usual music, there are scraps, wheezing and interference. The repair can be done at home.

Headphones are a pair of small-sized sound emitters that can be worn on the head or inserted directly into the ear canals

The following 7 breakdowns are most common:

Cable break;
Broken plug;
Microphone problems;
Speaker malfunction;
Volume control problems;
Defective temples;
Microphone mount malfunctions.

If you are faced with one of these problems, do not rush to go to the service store, you can carry out repairs yourself with your own hands. The first thing to do is understand why the headphones stopped working. Basically, breakage occurs because the wires of the headphones are bent and their wires are broken. In this case, the wire will need to be cut, cleaned and re-soldered. If the breakdown is related to something else, then you have to tinker.

If your wire comes off, it's not as easy as repairing the shackle, and if you just glue the last one, then here you need to find the breakdown, unsolder the connections, fix and re-solder. Sometimes the device cannot be repaired and will need to be replaced. The most common problem with modern headphones is wire breakage. This happens most often on headphones from a Sony or Samsung phone. Also, vacuum headphones from Sven, Sony, Panasonic, Beats, Dexp, Ergo, Samsung, Philips, Sennheiser and jbl are not insured against this. In order to fix this problem, you will need a number of tools.

In most cases, you will be able to repair the headphones yourself.

To begin with, we determine exactly where the wire broke, because very often the damage is not visible on the upper plane and there is no confirmation of the break. To do this, you will have to connect the headphones to a sound reproduction source, for example, a computer, or a phone and bend the wire until the sound appears, this must be done very carefully.

When you determine the required place, we proceed as follows:

You will need to take scissors and cut it at a distance of 2-3 cm from the problem point;
The insulating layer is removed, and the wires must be "tinned";
Take one of the available fluxes and prepare the cable for soldering;
Put the wires on a surface, it is better to use wooden blocks and press down with a soldering iron, repeat movements similar to cleaning varnish from a wire;
After the wires go through the tinning process, put the tubes on the cable and solder them taking into account the colors;
In order to make the work more reliable, fold the wires with the letter Z and wrap them with threads;
To make the cable look presentable, cover it with varnish or glue, this will add reliability.

The last point is desirable, since the threads will begin to unwind over time, and you will have to re-solder all the connections. You can check the work using a computer. Another important point, if the contacts are the same and you can forget where to connect which one, pinout will help you, that is, the numbering of each contact.

If you are faced with a broken plug, then get ready for the fact that you will have to disassemble and reassemble it. This applies to most cases.

It is necessary to work with the details carefully, each core of the wire is very thin and fragile
