Causes of noise in headphones:

You connected headphones to a computer or laptop, and instead of pleasant and favorite music you hear an annoying hiss or crackling noise, who will like that? At the same time, you do not understand why there is noise in the headphones, where it came from and what to do with it.

The most annoying thing about the noise effect in headphones is that it is very difficult to figure out why it appeared and how to fix it. There can be a lot of reasons for the cracking in headphones, the usual algorithm for finding the cause of poor performance of a headphone is to sequentially search through potential noise sources, exclude or isolate them, and then check them further. In theory, this looks simple, but in practice, such an algorithm is completely impossible to implement.

For example, you have only one computer, which is connected to an outlet that is embedded in a concrete wall, the apartment has been renovated and it is impossible to install the computer in another place, or another room, because there is no room for him. And therefore, we cannot rule out all possible reasons for the occurrence extraneous noise in headphones.

However, we can start with the simplest and most obvious potential causes of interference in headphones, and if their verification will not work, then we will only have to hope that this problem will eliminate itself in the future. For example, the neighbors will turn off the hammer drill, or after a while you will buy a voltage stabilizer through which you connect your computer.

So, let's start looking for the cause of the hiss in the headphones.

Damaged cable is a very common cause of hiss and crackles in headphones.

Let's start with the simplest and most common cause of extraneous noise in headphones - a damaged cable or poor contact in the socket.

Take a close look at the headphone cable, it must be absolutely intact, it must have the same density throughout its entire length. Feel the entire cable with your hands, perhaps there was an interruption in some place inside the cable, or once you bent the cable too much and the copper cores inside it broke off.

If, after visual and tactile inspection, the cable is not suspicious, check the jack, its joints and the very audio jack into which you plug the headphones.

Check how well you insert the jack into the jack, it should fit easily, with a slight click and hold firmly in it. The jack must go into the socket all the way, there must be no visible part of the jack.

Sometimes, due to the peculiarities of the structure of the nest, about 1 mm of the jack remains visible, but no more, and this is a rare phenomenon.

Poor contact is one of the most common causes of noise and crackling in headphones. Wipe the jack with a dry soft cloth, it may be dirty or covered with a layer of oxide.

If the wire does not cause suspicion and the jack is connected to the jack securely, but the noise remains, you need to continue the search.

Headphone technical condition - a possible cause of white noise

After checking the wire and jack has not yielded a result, you must definitely check the headphones themselves.

Examine them carefully, they may have recently fallen on a hard surface, cracks or other signs of damage have appeared on the case.

Be sure to try connecting the headphones to another audio source, such as a phone, TV, or tablet.

It is very important to understand and establish that the cause of the white noise in the headphones is not the headphones themselves, but the device to which they are connected.

If, when connected to another device White noise disappeared, which means that the headphones themselves are in order along with the wire and the jack, and we move on to further search for the occurrence of crackling.

Inexpensive speakers can cause noise in headphones

If headphone noise occurs when connected to a computer or laptop that has inexpensive multimedia speakers connected at the same time, the first step is to turn off the speakers and check if the noise in the headphones has disappeared.

The fact is that inexpensive speakers are assembled from cheap elements, but most importantly, when assembling them, they greatly save on soldering, wires and the general level of construction. Therefore, poor contact or short circuits may occur inside the speakers, which will induce interference throughout the electrical circuit, as a result of which there may be extraneous noise in the headphones.

The speakers must be turned off completely, and not just turned off their power.

If completely disconnecting the speakers from the computer did not help eliminate the noise in the headphones, proceed to the next troubleshooting step.

Lack of grounding is the most common cause of noise in headphones when connected to a computer

For some reason unknown to me, sockets in many homes are not grounded. In general, this is not so bad, traditional household appliances such as irons, heaters, filters and air conditioners work fine. But as soon as you connect equipment that is very sensitive to the quality of the power supply to an ungrounded power grid, problems immediately pop up.

A computer connected to an ungrounded outlet is a direct cost not only to noise in headphones, but also possible reason failure of the computer entirely due to exposure to static electricity.

The normal workaround for this problem is to ground the electrical outlet that the computer is connected to. But doing it yourself is not easy, if not impossible. To do this, you need to call an electrician, however, in this case, most likely, you will have to rewire the wiring throughout the apartment, and this is already a serious repair.

There is a simple way to check if grounding will really help eliminate noise in the headphones - to throw a wire from the computer to the battery.

You need to take an ordinary copper wire of small cross-section, on both sides with bare contacts. Lean one end against the computer case (preferably against the back wall), and the other against the battery. Leaning the wire against the painted part of the battery is useless, you need to lean against the metal of the battery, so you have to look for such a place. Usually, bare metal can be found on the back of the battery.

If you did everything correctly, and the noise is gone or significantly reduced, then the matter is in grounding.

Remember: grounding through the battery cannot be considered permanent decision... Such grounding can lead to the complete failure of the entire computer, it is enough for your neighbor to ground serious equipment to the battery, as the computer, having received a powerful discharge of electricity on the case, will fail. This is just a test, nothing more.

But what if you know for sure that the sockets are grounded, and the test with the wire yielded nothing? We continue to search for a crack in the headphones.

Microphone noise is one of the many causes of noise in headphones

We have considered possible sources the problems of noise in the headphones, which relate to material interference, now we are left with problems that relate to the configuration of computer equipment.

Microphone noise is one of the most common causes of noise in headphones. sound card.

Even if a microphone is not connected to your sound card, noise may be generated from the microphone jack.

In order to test this hypothesis, you need to go to the sound volume settings of your sound card, find the slider that adjusts the microphone volume level and reduce it to zero. Or, if there is such a possibility, turn off the sound from the microphone altogether.

If the reason for the noise in the headphones was the microphone input, then muting the sound from it should completely correct the situation.

In order to get to the microphone volume settings, open the control panel, find the item "Equipment and Sound" and go to it.

Now find the item "Sound" and go to it.

In the sound settings window go to the tab "Record", then find the active microphone (in my case, this is the Sound Blaster ZxR microphone), select it and click on the button "Properties" in the lower right corner.

In the new window, find the tab "Levels", and either slide the microphone volume slider to the maximum left until its value reaches zero, or click on the blue speaker icon to the right of the volume indicator. A red crossed-out mark should appear next to the speaker. This icon will indicate that the microphone is completely disabled in the system. It is preferable to turn it off, and not just to lower the volume level.

One of the types of problems with the microphone input or the microphone itself is its high sensitivity... This problem can be solved by turning on the microphone noise canceling mode.

Almost all modern sound cards have such a mode. If you find out that the microphone is the cause of the crackling, but you need it, then try turning on the noise canceling mode if you have one. This should fix the problem.

A problem with the volume level of sound sources in the sound card may be causing hiss in the headphones

Not only can noise from the microphone cause hiss in the headphones, the same noise can also be generated by the adjacent inputs of the sound card.

Depending on the model of the sound card, it may have additional inputs for connecting additional equipment. They can have the following names:

1. What U Hear
2. Line in
3. S / PDIF

Any of them, under a certain set of circumstances, can become a source of interference. Just as you turned down the microphone volume, you need to reduce or completely mute the sound from all of these jacks.

To do this, go to the panel Windows management.

Then find the item there "Equipment and Sound".

Then click on the section "Sound".

In the new window, go to the "Playback" tab, select the active speakers (a device that plays sound through the headphones in this moment) and click on the "Property" button.

Further, I cannot take a screenshot, tk. in my case, the volume level of all inputs and outputs is controlled through special software that controls my Sound Blaster sound card, in your case, most likely, the tab will be available "Levels", by going into which you can turn off all the inputs and outputs of your sound card.

To check, leave only the headphone output turned on, and turn off all other possible outputs and inputs or lower their volume to zero.

If the headphone hiss problem was at one of these points, it should disappear.

Volume level - paradoxical, but true, it can cause interference in headphones

In some cases, the volume level may cause interference to the headphones.

Sometimes it happens that the headphones have their own volume control, plus there is an additional volume control in Windows, and there is also a volume control in the application from which you are listening (game, player).

In order for any hardware that has its own hardware volume control to work well, you need to make sure that all software volume controls (especially the main volume slider in Windows) are set to 100%. And the final volume control is done with the hardware volume control.

To eliminate hiss, follow these steps:

1. Completely mute the sound in the headphones using the hardware control (buttons or knobs on the headphones themselves)
2. Set the volume in Windows to 100%
3. Set the volume in the app to 100%
4. Start gradually adding the volume on your headphones and bring it to a comfortable level.

The fact is that the software volume controls artificially reduce the volume of the sound, after which you have to crank the volume in the headphones to the maximum in order to listen to it at a comfortable level. However, for any equipment, be it headphones, speakers or a car engine, long-term work at the limit of the possible is extremely detrimental to the characteristics and properties of the unit.

When you set the hardware to the maximum volume on the headphones, you amplify all the noise that comes from the computer, plus you add distortion that appears in the headphones themselves at the maximum sound level.

Therefore, you need to adjust the volume using the method that I indicated in order to minimize possible distortion and noise from the headphones themselves, as well as remove the artificial amplification of unwanted noise.

Connecting any device to a computer is a process that requires special attention. The more complex the peripheral component, the more difficult the procedure is. Very often, headphones / speakers and microphones are connected to computers. These elements help you communicate online. It is very difficult to imagine a modern user without them.

On the one hand, connecting headphones and a microphone does not require anything special. Only after the implementation of the idea in life, it is often necessary to set up these components for a long time. They don't work well. Most often, users think about how to remove noise from headphones on a computer. Why does it appear at all? What will it take to fix the problem? And can you really get rid of it? If you can answer all questions asked, plugging in a headset and working with sound on a PC won't be a hassle.

Why is there noise

Initially, it is important to understand where the noise in the headphones comes from. Many users face this problem. Sometimes this is a temporary phenomenon, in some cases the noise does not disappear for a long time.

In fact, the nature of the problem is varied. Noises in headphones (with or without a microphone) occur for a variety of reasons. It is problematic to predict what kind of alignment helps to correct the situation. For example, noise can be caused by hardware damage or out of order. The next step is to figure out how to get rid of the noise on the computer.

Sound card

The first reason that can affect the sound quality in operating system- this is bad If it is damaged or out of date, noise appears in the headphones.

The sound "breaks", various crackles, creaks and other noises may appear in the headphones or speakers. The situation is corrected only by replacing or repairing the sound card. Only then will the headphones disappear.

Earthing

The next problem is very rare. We are talking about the lack of grounding at the sockets to which the headset and speakers / headphones are connected in general. V this case all sorts of noises may appear.

If we are talking about a laptop, most likely, connecting the computer to a grounded outlet will not fix the problem. As a rule, laptops have boards on mother card may not be grounded. We'll either have to replace them, or come to terms with the problem. In some cases, users prefer not to use a particular laptop.

USB devices

Do you hear noise in the headphones on your computer? Usually, different kinds of sounds occur when connecting various devices. They appear immediately, not after a while.

For example, when attaching a mouse, you may hear a monotonous sound. And if we are talking about the keyboard, most likely, you will hear clicks when you press the keys.

This happens due to:

1. Active transfer of information to the computer. Then it is recommended not to connect USB devices to these or those ports. It is advisable to find other places. Or even start using wireless headset and other devices.
2. Damaged USB port. It is suggested to carry out a repair. In practice, users simply reconnect all devices to different ports.

Fortunately, this situation is not very common. Modern computers and laptops are designed so that users can work comfortably at the machines. Therefore, such an alignment is unlikely to occur in practice.

Cable

How to remove noise from headphones on a computer? Much depends on what kind of headset the user has. The point is that now all devices are divided into wired and wireless. This feature plays an important role.

Often, noise in speakers or headphones is found on models that are connected via a cable. This is the main problem. For example, if the cable is damaged from a microphone or headphones, all sorts of noises occur. This happens due to poor quality information transfer to the sound card.

It is likely that the cable is damaged. Then the breakdown must be eliminated. If you are using wireless, such a layout will not help.

Another trick for users with a wired headset is to unplug the cord and plug it back into the computer. It is this method that often helps to get rid of noise.

Drivers

But the next source of the problem is relevant for all devices. But in practice, it is rare. The thing is that the strong noise in the headphones on the computer is the result of damage or the absence of a sound card driver or device.

In such a case, you just need to reinstall or update the appropriate software package for the normal operation of the operating system with the connected device. For wireless headphones, as a rule, the corresponding drivers are included in the kit on a separate disc. As a last resort, you can download them from the website of the manufacturer of your sound card or headset.

Maximum sound - problems are assured

Background noise in headphones of any model is often encountered when the sound settings are incorrectly set. It doesn't matter if a microphone is connected to the PC or not. Indeed, in this situation, nothing depends on him.

If the sound settings are set to maximum, you may experience noise or wheezing on your computer. Users who buy cheap speakers or headsets suffer from a similar problem.

Everything is corrected simply - by reducing the sound. For example, through a mixer in the operating system. You just need to click on the gramophone image (near the hour and date), then move the slider down. So that the noise disappears. Nothing difficult or special. That is why it is recommended to buy mid-priced headphones. They face a similar problem less often.

Microphone - good or bad

Now it is clear how to remove noise from headphones on a computer. But these are far from all the tricks that can help. What if all the previously listed scenarios did not fit?

The presence of a microphone on the PC plays an important role. It is he who often becomes the source of noise in headphones. What to do?

It is clearly not worth giving up the microphone. Instead, you will have to make small adjustments to the sensitivity and volume of the device. Then you will be able to get rid of unnecessary noise.

How to do it? It takes a little instruction to follow. It looks something like this:

1. Load your computer. Be sure to connect a headset with a microphone.
2. Click on the mixer on the right side of the RMB screen. In the menu that appears, click on "Sound recording devices ...".
3. Find the connected microphone. Double click on the corresponding line.
4. Go to the "Levels" tab.
5. Adjust the volume and sensitivity of the microphone by moving the sliders. If there is a PC Beep, turn it off (move the volume mark to zero).
6. In the "Improvements" section, check the box next to "Reduce noise level". You can also check the "Remove constant component" item.

All this will help to get rid of the noise in the headset very quickly. How do I set the correct microphone settings? This is an individual component, each user independently selects the option that suits him.

Conclusions and conclusions

It doesn't matter which headset is connected to the computer - wired or not. The main thing is that the bulk of the problems are found on all device models. for a computer with a microphone are connected and used most often without much difficulty. And the main reason for the noise in the headset is the high sensitivity of the microphone, as well as the really loud environment around the user.

How to remove noise from headphones? All of the above techniques will definitely help to correct the situation. If we are talking about a wireless headset, then in case of constant noise, it is recommended to change the USB socket used as a receiver. Otherwise, all the tips listed earlier remain the same.

Extraneous noise in headphones occasionally occurs due to infection with viruses. After the computer is disinfected, the headset starts working properly. Fortunately, this kind of event is not that frequent. And the main methods of dealing with the problem under study are to reinstall the driver, reduce and adjust the microphone. From now on, it is clear how to remove noise from headphones on a computer.

Currently, there are many types of different bluetooth headphones, headsets and speakers to choose from that receive sound using this protocol. Very often, when buying inexpensive headphones, there are problems with the sound quality, namely, sound stuttering and lagging. There are several ways to solve this problem ...

The main problem of bluetooth headphones stuttering is the quality of their workmanship and the incompatibility of standards. The problem may be in the insensitive antenna and the power of the processor built into the device. And accordingly, there may be a lack of power on the transmitting device: computer, tablet, phone and bluetooth module inserted into USB port PC, as well as the incompatibility of the BlueTooth version.

It was also noticed that the headphones work well indoors, but on the street the connection is constantly interrupted. In a room where there are walls nearby, the signal bounces off the walls and goes to the receiver of the wireless headset and everything works fine. Where there are no walls, the sound is lost.

It has been noticed that the same headphones work fine on one smartphone, but stutter on the other. And it so happens that everything was fine, but after installation new program or app updates, sound out of sync appears. This is also observed when the screen is turned off. mobile device or when the phone goes into locked mode.

Especially often there is a break in sound when installing, deleting or copying files from a USB flash drive to a USB flash drive. Since at this moment the resources of the system are being used. All this degrades the sound quality in the headphones. If this happens, then it must be borne in mind that the processor's power is not enough to compress the sound and transmit it via the Bluetooth protocol.

Clean, loud noise without wires.

The main advice, before buying a bluetooth headset, check the quality of its reproduction, as they say, "without leaving the checkout", immediately in the store. If this is not possible, keep the receipt and packaging of the product for returning it back to the point of sale.

What if the product cannot be returned to the store?

How to solve the problem of sound stuttering in bluetooth headphones?

1.If you have a PC and the USB bluetooth module is plugged into the back port of the computer. Then transfer the USB-Bluetooth to the front side of the PC. Better yet, buy a USB hub on a wire, raise it higher and plug the USB-BlueTooth module into it. If the bluetooth adapter is old, then it is better to change it to a newer and more modern one.

Updating Bluetooth driver in Windows Task Manager.

2.If you have a PC, change the drivers in the Device Manager to "Sound and Gaming Devices"and in the subsection" BlueTooth ". Here you need to start the search for drivers Windows tools... To do this, select the "Update" item.

If this does not help, then you should try to set different versions drivers and check, some can work.

When syncing with a PC, older models of Bluetooth headphones may have compatibility issues with Windows drivers.

3.On the street, to avoid interruptions in music playback, put your smartphone as close to the headphones as possible. Move your smartphone from pocket to pocket, and the higher up to the headphones, the better. Or put it in the top, inner pocket of your jacket. Do not use headphones in cold weather.

4.In the settings of the player or in the settings of the audio device on the PC, lower the playback quality of the audio stream, i.e. if you listen to music at 320kbps or more, try the sound no more than 128kbps. Audio mp3 files should be recorded with low bit rate.

If you have a laptop with weak speakers and when you play the next movie, the volume of the built-in speakers is not enough for comfortable viewing, then you can use the tips to increase the volume on your laptop or phone.

5. Make the BT mode on the transmitting device "Visible to all". In this mode, the system loads the processor less.

6. Bring the devices closer to each other for a few seconds or pause the sound playback in the player or youtube, this is necessary to synchronize the devices. For complete synchronization sound may take a few seconds.

7. In Android 6.0 in the settings there is an item: "Application permissions", in it "Transfer via bluetooth". Here you need to uncheck all the boxes, except for "Volume". Here we click: "Change Settings" and select the item "Do not disable".

8.Android OS kernel can be overclocked via special programs types: SetCpu, Tasker, Antutu CPU, Tegrak, OverClock and others. Changing the operating parameters of the OS is done in the "Performance" section. The following values ​​must be changed: Governor in "perfomance", Scheduler in "cfq". Another recommendation is this solution: installing Kernel Adiutor with CPU Governor in the ondemand position (+ "Apply on boot" for convenience).

9. To reduce the load on the system, you can use special software. There is a Droidwall program that can control the Internet access of each Android OS application. To reduce the load on the processor, deny access to the Internet for applications that are not needed at a given time. This can be done through the program menu.

10. Soldering the antenna in the headphone or bluetooth speaker case. If you remove the housing cover, there should be a serpentine track on the board. The craftsmen solder a piece of copper wire 4-5 centimeters to this track. After that, the signal quality improves and the sound stops stuttering.

Video: 5 Bluetooth headphones. Parcel from China.

11. To reduce the load on the processor on the PC, you can also turn off the microphone on the bluetooth headset. To do this, go to Control Panel => Sound => Recording => Microphone => Properties => Listen => uncheck "Listen with this device". And restart your computer.

12. Interference from other devices greatly affects the quality of the connection. If wireless speaker or the sub is next to a router, TV, computer, microwave oven and other sources of radio interference, then she / he must be moved away.

13. Poorly charged battery - the reason for the lack of processor power of the bluetooth device.

14.Old models of bluetooth headsets may not be compatible with newer smartphones and vice versa. This is the main reason for the instability and stuttering of music. Therefore, before buying a wireless device, you should always check whether these two mobile devices will connect well.

You can read more about the BlueTooth protocol in the article on habrahabr.ru. It analyzes the signal loss process with screenshots and graphs.

Analysis of the impact of the human body on the transmission power of audio data via the BlueTooth protocol.

The picture above shows that from the dump you can see that the bitpool value for this portion of traffic is 48, but as soon as I closed the path from the laptop to the column with my body, the bitpool value began to decrease, accompanied by interruptions and clicks.

After the bitpool value settled at 30, the clicks disappeared, and the audio playback became uninterrupted again. Everything indicated that the codec performed auto-tuning, noticing degradation in signal quality.

But did I really introduce such a significant attenuation with my mortal body? Well, time to take a look at the graph showing the power level of the received signal.

The world has stepped into the wireless era. Keyboards and mice, data transfer, Internet access - everything has long gone away from cables. However, there are still certain things that literally hold us like a stone in this terrible world of wires. And besides the most obvious - for example, chargers, there are also less noticeable, but far from less important accessories - headphones. After all, you see, not everyone has to like every time to think about where and how to "stick" the wire just to go out into the street. And when playing sports, it is generally better not to remember about headphones. What is really there - hasn't it ever annoyed you that they should be taken off in order to get up from the computer? Therefore, for many, the question of buying wireless headphones is quite acute. It would seem that there is everything for this - on this moment this market is already saturated enough to find a suitable option. But, unfortunately, there are a number of problems. Indeed, in fact, bluetooth headphones have not made significant quality breakthroughs since their inception.

But on a certain day, such a question came before me. Confident that the technology had matured by the current year, I quickly chose my gadget - Jabra Halo 2. [Lyrical digression]: yes, we can say that the Jabra Halo 2 is not an indicator and a bad example. However, not every average buyer can afford an advanced technique like or - although it is possible that they will be devoid of all the disadvantages listed below. Moreover, even Jabra Halo 2 cannot be called budgetary - let me remind you that for the same one thousand hryvnia you can buy quite serious wired headphones [end of lyrical digression]. And after almost a year from the beginning of operation, he is ready to tell about all aspects of life with bluetooth headphones of the middle class.

The first minus surfaced almost immediately - as soon as the phone is in the jeans pocket, the signal starts to be lost. I had to put the phone in a jacket pocket, jacket, or in a bag (however, it turned out that communication is established much better in the right jeans pocket, but this did not completely solve the problem). Anyway, audio interruption is the most common problem. Interference can find you literally at any time, and it is so nasty that you involuntarily start to twist the phone in your pocket in search of the "optimal position". Moreover, it happens that the signal is affected by the environment - near the local stadium, for example, interference is almost always observed. Also, the gap will follow you in the first minute or two after connecting to the device.

The second issue is sound quality. Yes, in fact, bluetooth headphones sound great - but with the wire connected. Wirelessly, they are only suitable for listening to podcasts, radio, watching videos from YouTube and chatting with friends. Music connoisseurs will turn up their noses in disbelief (and rightly so), although not particularly picky users (like me) will be satisfied with such.

And it is logical that the speed of work is a little lame. From the sound itself to its playback in the headphones, it takes some time within a second. Moreover, from the very first day, the user will notice that before starting to play sound, the headphones will turn on a barely noticeable noise (it is completely lost against the background of music), and when playback is over, this noise will disappear, while with a rather sharp click, which on high level volume can hit your ears perceptibly. However, you can get used to it quickly enough.

And at least these three minuses already predetermine the fate of wireless headphones. There is no practical sense in them. It can be seen that this direction is gradually developing, but at the moment it is a waste of money. One gets the feeling that the market exists in order for it to exist at all - but there will still be a user. Trust me, freedom from wires is not worth all the problems described above. Although there are positive aspects of using such headphones, my advice to you is: either buy expensive bluetooth headphones, or take good and wired ones.

Despite the technological advancements, Bluetooth headphones still suffer from some nasty issues.

We've looked at the most common Bluetooth headphone problems and found several solutions.

My smartphone cannot find the bluetooth headphones

Do you want to connect headphones to your smartphone, but for some reason the headphones do not appear in the list of Bluetooth devices? Here is a list of how to fix the problem:

• Check if you have actually turned on the Bluetooth connection on your phone. Surprisingly easy to miss.
• Check if your headphones are compatible with your device and OS. If you are using an iPhone, it must run at least iOS 7, which natively supports "Bluetooth Smart Ready". If you're on Android, make sure it runs at least Android 4.3.
• Make sure your smartphone and headphones are close enough to each other when you want to connect them. The best way to ensure a good connection, this is to bring the devices at least 50 cm from each other.
• Check the manufacturer's recommended connection process. Not all Bluetooth headphones will connect to your phone in the same way; sometimes it's as easy as just plugging in your headphones, other times it's a little more complicated. To avoid connection problems with your device, please read carefully all the detailed steps on what you should do.
• Try turning them off and on again. it old method but let's face it - sometimes it does work.
• Turn off or remove all interference. Perhaps for some reason, your headphones are trying to connect to a device other than your smartphone.
• Move away from your Wi-Fi router. Perhaps your wifi router uses the same spectrum as the headphones and thus causes some interference.

My bluetooth headphones turn off periodically

There is nothing more frustrating than listening to music when all of a sudden your Bluetooth headphones just go off. Sometimes the Bluetooth connection disconnects completely and forces you to reconnect, other times it will disappear for a few seconds before it reconnects. These problems are easy to solve:

• Keep within the range of your headphones and smartphone. It is very easy to move away from the smartphone and the bluetooth will not work.
• Delete any unnecessary Bluetooth connections. It is possible that your smartphone is "overloaded" with the number of attempts to connect to it.
• Make sure your Bluetooth headset is well charged. Bluetooth earphone have a tendency to intermittently shut down when the battery is low.
• Try unplugging the headphones and then pairing them with your smartphone again.

The connection between my headphones and my smartphone is unstable

It also often happens that when you try to pair your headphones and smartphone together, you will either get an error message or the pairing process will be unstable - without actually pairing. The simplest solution is here:

• Remove any unused or unnecessary Bluetooth connections. Some devices start to freeze when there are too many devices in the Bluetooth connection list.

If that doesn't work, you can try any of the other methods we have already indicated.

I hear noise in the Bluetooth headphones

Despite the long journey, Bluetooth technology is still susceptible to interference such as static or crackling noises when listening to music.

• First, you must disable or disable others unused devices Bluetooth in the area.
• If the static persists, try restarting your headphones (you can easily figure this out by referring to the manufacturer's website).
• Turn on the media player, then unplug the headphones for 30 seconds and then reconnect them.
• Reduce the distance between your smartphone and the earbuds, as this also helps reduce (or even fix) any noise issues.

These are all proven methods of solving some of the more troublesome bluetooth problems, but this is not a complete list. If none of these troubleshooting methods work, it's best to contact the manufacturer directly.

Have you tried any of these methods to fix problems with your own Bluetooth devices?
