Despite the ease of operation, sometimes we still encounter certain problems, such as extraneous sounds like hissing and wheezing, due to which the overall sound quality deteriorates significantly. To fix this problem, you need to know the possible causes of its occurrence.
It is important to know that, despite the elementary nature of this device, to a person who has not previously encountered problems in his work and eliminate them, this problem may seem very serious.
In order to understand where the hiss in the headphones comes from, you need to understand at least a little how they are arranged. Pay attention to whether you hear hissing sounds constantly or only intermittently.
One of the reasons why this problem may occur is the incorrect connection of the headphones, or rather, the selection of the wrong settings. In addition, if the headphones are not new, check if the contacts with which you connect them are working.

Noises in the headphones caused by a malfunctioning sound card
Such a detail as a sound card has the most direct impact on how well the melody is reproduced by the equipment. If the part is defective, the personal computer cannot accurately transmit sound signals, which is why the normal sound is complemented by hissing, crackling, the sound seems to “break” and “jump”. In this situation, only the replacement of a defective part will help, and then the sound will no longer be accompanied by extraneous noise.
Faulty wires
The manufacturer of the model is often responsible for the correct operation of the headphones and the correct transmission of sounds.
You should know that there are two types of headphones: wireless and wired. Extraneous sounds, as a rule, appear in models that work through a cable connected with a plug. If the copper strand of the cable is damaged or stretched, noise interference and intermittent sound breaks will occur.
A damaged wire often leads to noise in the headphones on the iPhone. This is due to the fact that the material of the cable is thin and flexible, it breaks easily. A damaged conductor sends incorrect signal characteristics to the sound card, and this is reflected in the sound. How to eliminate wheezing headphones? This can be done by removing a torn or bare section of the wire, in extreme cases, you will have to buy new fittings.
Broken USB input
Incorrect sound may occur after connecting other gadgets to the USB connector. A mouse, or a faulty keyboard, can cause the problem. In this case, pressing the key, you will hear clicks. There are quite objective reasons why this happens.
When information is transmitted, the load on the PC increases. To reduce it, you need to do the following:
1. Switch the plug to another port.
2. You can also purchase a splitter and fix the old connectors to connect.
3. Start using wireless devices.
The problem is that very often users do not pay due attention to the computer, they do not immediately repair the problems that have appeared. As a result, USB connectors become unusable one after another, and only one remains, into which a splitter is connected and it is on it that the entire load falls, which causes its increase.
How to wear in-ear headphones correctly 
Mouse noise
When you scroll the page with the mouse, sometimes you can also notice noises, sometimes they are just unbearable. The solution to the problem is to replace the mouse, switch the mouse to a nearby USB port, or install an external sound card.
Lack of grounding sockets
This problem is not often, but still occurs, interfering with the normal operation of the headphones. Lack of grounding can also cause pops, clicks and other noises in the headphones. If you have already checked your headphones and found no problems, also check the outlets that your computer is connected to.
This nuance applies only to desktop computers, laptop boards are usually grounded at the stage of their production.
When you use headphones connected to a laptop, incorrect sounds are most likely caused by internal device malfunctions. Do not delay contacting the service center, where your device will be diagnosed for problems.
The sound source itself does not work correctly
Violation of the rules for using headphones often leads to a violation of their work, and in particular to the sound. Also, problems arise in the operation of the main sound source. Rarely, but still, driver errors occur. Program errors and failures in the operation of the operating system cause interference in the form of noise and crackling.
The problem can be detected by checking the device by connecting various headsets. If their work is equally unacceptable - unpleasant sounds will be heard in all headphones, then the problem lies precisely in the device driver.
If you are used to listening to music at a very high volume, you may also notice the appearance of hiss and crackling. As a rule, this happens if you purchase inexpensive headphones.
Insufficiently powerful power supply is another reason for extraneous noise when headphones sound (this problem sometimes occurs with laptop owners who have not yet figured out all its features). Fixing this issue is easy with the following tips.
On your laptop, go to "Control Panel", then to "System and Security" and finally to "Power Options", and select the "High Performance" mode. After completing the setup, check the sound quality in the headphones.
They are getting more and more widespread. Smartphone manufacturers themselves are pushing to make a purchase, eliminating the 3.5 mm audio jack from new models. Everything would be fine if not for one "but". The sound quality in wireless headphones is often average or even poor. And the user may experience audio delay in Bluetooth headphones. What caused these two troubles? Is it possible that large companies still cannot come up with a normal method of transmitting sound over the air?
If it is quite possible to put up with the average sound quality, then when the music is interrupted, it quickly infuriates. These second or even half-second pauses make you return to wired headphones, connecting the accessory at least through an adapter.
Unfortunately, it is almost impossible to find out the exact causes of micropauses. The fact is that Bluetooth is very different from the same Wi-Fi - this method of signal transmission is less standardized, and the power of the "blue tooth" is often not enough. If Wi-Fi quietly penetrates even through the walls of the house, then even the lining of the jacket can interfere with the Bluetooth signal. That is, try to pull your smartphone out of your inner pocket - it is possible that the purity of synchronization will improve significantly.
Unfortunately, the sound in Bluetooth headphones is delayed even when the accessory is right next to the smartphone. This indicates the low compatibility of the chip in the headset with the module in the phone. It is possible that some unsuitable codec is used last. After all, if you did not know, not analog, but digital sound is transmitted through the air. Headphones still need to decrypt it, only after that playback occurs. If the electronics in the product is not the most powerful, then from time to time micropauses can really occur.
If you are planning to buy Bluetooth headphones, then be sure to check the technical specifications of the accessories. Try to choose an instance that supports exactly those profiles that are built into the Bluetooth of your smartphone. It is also desirable that the version of the "blue tooth" is also the same. In particular, now many smartphones have Bluetooth 4.0 on board - a wireless headset should also have a similar version.
If the headphones are connected to a computer, then to eliminate the interruption of the sound, you can “play around” with the settings of the music players. Change the sound output from DirectSound to WaveOut - sometimes this can help. Unfortunately, in smartphones, there are noticeably fewer Bluetooth connection settings, so you can’t really indulge in experiments here.
Bad sound
The sound quality depends on several factors. Basically, this parameter is affected by the Bluetooth version. In each fresh version, some new profiles and technologies appear. For example, now smartphones and wireless headsets are gradually switching to the AptX HD codec, which provides sound transmission in almost CD quality. If you are not limited in financial resources, then it is better to purchase an accessory with support for just such a codec. But do not forget that then you will need an appropriate smartphone.
The sound quality also depends on the music files being played. Pay attention to the bitrate of MP3 music - files with a 320 Kbps parameter will have the best sound. Real music lovers should switch to files with a lower compression ratio - for example, FLAC. Such music will weigh more, but when saving these compositions, too high or too low frequencies are not cut out. However, an increased bitrate can lead to micro-pauses - the data transfer rate via Bluetooth is very limited.
Of course, first of all, the purity of the sound depends on the design of the headphones themselves. It is foolish to expect a good sound from the simplest "plugs" for 2000 rubles. Want to enjoy music without using a wired connection? Then you have to fork out for an expensive headset from a well-known manufacturer. Difficult to choose? Focus on the collection.
Conclusion
Alas, modern wireless technologies used to transmit sound do not allow you to somehow play around with the settings. If there are any problems, then this most often indicates poor compatibility between the headphones and the smartphone. And in the case of insufficiently good sound, the unfinished design of the headset (or a weak chip) should be blamed. That is why when choosing wireless headphones you should not save.
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 must admit, not everyone has to think every time about where and how to “poke” the wire just to go out into the street. And when playing sports, it’s better not to remember about headphones at all. Why, didn't it ever annoy you that you had to take them off to get up from the computer? Therefore, for many, the issue of buying wireless headphones is quite acute. It would seem that there is everything for this - at the moment this market is already saturated enough to find a suitable option for yourself. But, unfortunately, there are a number of problems. After all, in fact, bluetooth headphones have not made significant qualitative breakthroughs since their inception.
But on a certain day, such a question arose in front of me. Being confident that by the current year the technology had already matured, I quickly chose my gadget - Jabra Halo 2. [Digression]: Yes, you can say that Jabra Halo 2 is not an indicator and a bad example. However, not every average buyer can afford advanced technology like or - although it is possible that they will be devoid of all the shortcomings listed below. Moreover, even Jabra Halo 2 cannot be called a budget one - let me remind you that for the same one thousand hryvnia you can buy quite serious wired headphones [end of digression]. And after almost a year since the start of operation, I am ready to tell about all aspects of life with middle-class bluetooth headphones.
The first minus surfaced almost immediately - as soon as the phone is in a jeans pocket, the signal starts to get lost. I had to put the phone in the pocket of a jacket, jacket, or in a bag (however, it turned out that the connection is much better in the right jeans pocket, but this did not completely solve the problem). And in general, audio interruption is the most common problem. Interference can catch you literally at any time, and they are so nasty that you start to involuntarily turn the phone in your pocket in search of the "optimal position". Moreover, it happens that the environment affects the signal - near the local stadium, for example, interference is almost always observed. Also, the gap will haunt you in the first minute or two after connecting to the device.
The second issue is the sound quality. Yes, in fact, bluetooth headphones sound great - but with a wire connected. On a wireless connection, they are only suitable for listening to podcasts, radio, watching YouTube videos and chatting with friends. Music connoisseurs will turn up their noses in disbelief (and rightly so), although not particularly fastidious 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 the sound, the headphones will turn on a barely noticeable noise (it is completely lost against the background of the music), and when the playback is over, this noise will disappear, while with a rather sharp click, which is at a high level. The volume level can hit your ears quite a bit. However, you can quickly get used to this.
And at least these three minuses already predetermine the fate of wireless headphones. They have no practical meaning. It can be seen that this direction is gradually developing, but at the moment it is a waste of money. There is a feeling that the market exists in order for it to exist at all - but there will still be a user. Believe me, freedom from wires is not worth all the above problems. 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.
Currently, there are many types of different bluetooth headphones, headsets and speakers that receive sound using this protocol. Very often, when buying inexpensive headphones, there are problems with sound quality, namely sound stuttering and its delay. There are several ways to solve this problem...
The main problem with stuttering bluetooth headphones 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 the USB port of the PC, as well as the incompatibility of the BlueTooth version.
It has also been noticed that the headphones work well indoors, but the connection is constantly interrupted outdoors. In a room where there are walls close, the signal bounces off the walls and hits the wireless headset receiver 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 another. And it happens that everything was fine, but after installing a new program or updating the application, the sound is out of sync. This is also observed when the screen of the mobile device is turned off or when the phone goes into locked mode.
Especially often there is a break in the 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 power is not enough to compress the sound and transmit it via the Bluetooth protocol.
Clear, loud sound without wires.
The main advice, before you buy a bluetooth headset, check the quality of its reproduction, as they say "without leaving the cash register", right in the store. If this is not possible, keep the receipt and packaging of the goods in order to return it back to the point of sale.
What should I do 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 a USB bluetooth module is inserted into the rear port of the computer. Then transfer the USB-Bluetooth to the front of the PC. Better yet, buy a USB hub on a wire, lift it up 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.
Update Bluetooth driver in Windows Task Manager.
2.If you have a PC, change the drivers in the Device Manager to "Sound and Game Devices" and in the "BlueTooth" subsection. Here you need to start searching for drivers using Windows tools. To do this, select "Update".
If this does not help, then you need to try to install different versions of the drivers and check if some one can work.
When syncing with a PC, older Bluetooth headphones may have compatibility issues with Windows drivers.
3. While outdoors, to avoid interruptions in music playback, place your smartphone as close to the headphones as possible. Shift your smartphone from pocket to pocket, and the higher 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 player settings or in the audio device settings on the PC, lower the audio stream playback quality, i.e. if you listen to music at 320kbps or more, try no more than 128kbps. Audio mp3 files must be recorded with a low bitrate.
If you have a laptop with weak speakers and when playing 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. It may take a few seconds for the audio to fully sync.
7.In Android 6.0 in the settings there is an item: "App Permissions", in it "Transmission via bluetooth". Here you need to uncheck all the boxes except "Volume". Here we click: "Change Settings" and select the item "Do not disable".
8. The Android OS kernel can be overclocked through special programs such as SetCpu, Tasker, Antutu CPU, Tegrak, OverClock and others. Changing the parameters of the OS is done in the "Performance" section. The following values need to be changed: Governor to "perfomance", Scheduler to "cfq". They also recommend this solution: setting Kernel Adiutor with CPU Governor to ondemand (+ "Apply on boot" for convenience).
9. You can reduce the load on the system using special software. There is such a Droidwall program that can control Internet access for each Android OS application. To reduce the load on the processor, prohibit applications that are not needed at the moment from accessing the Internet. This can be done through the program menu.
10. Soldering the antenna in the case of headphones or bluetooth speakers. If you remove the case cover, then the board should have a snake-shaped track. Craftsmen solder a piece of copper wire 4-5 centimeters to this track. After that, the signal quality improves and the sound stops stuttering.

11. You can also reduce the processor load on your PC by turning off the microphone on the bluetooth headset. To do this, go to Control Panel => Sound => Recording => Microphone => Properties => Listen => uncheck "Listen to this device". And restart your computer.
12. Interference from other devices greatly affects the quality of the connection. If a wireless speaker or subwoofer is next to a router, TV, computer, microwave and other sources of radio interference, then it / it must be moved away.
13. A poorly charged battery is the reason for the lack of processor power of the bluetooth device.
14.Older models of bluetooth headsets may not be compatible with new smartphones and vice versa. This is the main reason for 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 an article on habrahabr.ru. It analyzes the signal loss process with screenshots and graphs.

After the bitpool value settled down to 30, the clicks disappeared and audio playback became continuous again. Everything indicated that the codec performed autotuning, noticing the degradation of signal quality.
But did I really bring in such a significant attenuation with my mortal body? Well, it's time to take a look at the received signal strength indicator graph.
Connecting any device to a computer is a process that requires special attention. The more complex the peripheral component, the more difficult the procedure. Quite 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 idea is brought to life, it often takes a long time to configure these components. They work with errors. Most often, users think about how to remove noise in headphones on a computer. Why does he even show up? What is required to fix the problem? And can you really get rid of it? If you manage to answer all the questions asked, connecting a headset and working with sound on a PC will not cause trouble.
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 various reasons. It is problematic to predict which alignment helps to correct the situation. For example, noise can be caused by hardware damage or broken settings. Next, you have to figure out how to get rid of noise on the computer.
Sound card
The first reason that can affect the sound quality in the operating system is a bad one. If it is damaged or outdated, noise appears in the headphones.
The sound "breaks", a variety of crackling, creaking and other noises may appear in the headphones or speakers. The situation is corrected only by replacing or repairing the sound card. Only after that the headphones will disappear.
grounding
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. In this case, various kinds of noise 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, for laptops, it is the boards on the motherboard that may not be grounded. You will either have to replace them, or put up with the problem. In some cases, users prefer not to use a particular laptop.
USB devices
Noise in the headphones on the computer? Usually different kinds of sounds occur when you connect a variety of devices. They appear immediately, not after a while.
For example, when a mouse is attached, a monotonous sound can be heard. And if we are talking about the keyboard, most likely, clicks will be heard when pressing the keys.
This happens due to:
- Active transfer of information to the computer. Then it is recommended not to connect USB devices to any of the ports. It is advisable to look for other places. Or even start using a wireless headset and other devices.
- USB port damage. It is proposed to carry out a repair. In practice, users simply reconnect all devices to other ports.
Fortunately, this situation does not occur very often. Modern computers and laptops are designed so that users can work comfortably at the machines. Therefore, such an arrangement is unlikely to be encountered in practice.
Cable
How to remove noise in headphones on a computer? Much depends on which headset model the user has. The thing 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 connected via cable. Therein lies the main problem. For example, if the cable from the microphone or headphones is damaged, all sorts of noises occur. This happens due to poor-quality transmission of information to the sound card.
It is likely that the cable is damaged. Then the damage must be repaired. If wireless is used, such a layout will not help.
Another trick that is advised to users with a wired headset is to unplug the cord from the jack and plug it back into the computer. It is this method that often helps to get rid of noise.
Drivers
But the following source of the problem is relevant for all devices. But in practice it rarely occurs. The thing is that the strong noise in the headphones on the computer is a consequence of damage or lack of a sound card or device driver.
In such a case, you simply need to reinstall or update the appropriate software package for the operating system to work properly with the connected device. For wireless headphones, as a rule, the corresponding drivers are included on a separate disk. As a last resort, you can download them from the sound card or headset manufacturer's website.
Maximum sound - problems are guaranteed
Background noise in headphones of any model is often found when the sound settings are incorrectly set. It doesn't matter if a microphone is connected to the PC or not. After all, nothing depends on him in such a situation.
If the sound settings are set to maximum, you may experience noise or wheezing on your computer. Users who bought cheap speakers or a headset suffer from a similar problem.
Everything is fixed simply - by reducing the sound. For example, through a mixer in the operating system. You just need to click on the image of the gramophone (near the clock and date), then move the slider down. So that the noise disappears. Nothing difficult or special. That is why it is recommended to buy average-priced headphones. They are less likely to experience this problem.
Microphone - good or bad
Now it’s clear how to remove noise in headphones on a computer. But this is not all the tricks that can help. What to do if all the previously listed options for the development of events did not fit?
An important role is played by the presence of a microphone on the PC. It is he who often becomes the source of noise in the headphones. What to do?
It is clearly not worth giving up the microphone. Instead, you will have to make a small adjustment to the sensitivity and volume of the device. Then it will be possible to get rid of excess noise.
How to do it? It is required to follow a small instruction. It looks something like this:
- Download computer. Be sure to connect a headset with a microphone.
- Click on the mixer on the right side of the RMB screen. In the menu that appears, click on "Sound recording devices ...".
- Find the connected microphone. Double click on the corresponding line.
- Go to the "Levels" tab.
- 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).
- In the "Improvements" section, check the box next to "Reduce noise". You can also check the item "Removing the constant component".
All this will help to get rid of the noise in the headset very quickly. How to correctly set the settings for the microphone? This is an individual component, each user independently selects the option that suits him.
Findings and Conclusions
It doesn't matter what headset is connected to the computer - wired or not. The main thing is that the majority of problems occur on all models of devices. for a computer with a microphone are connected and used most often without much difficulty. And the main cause of 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 in headphones? All of the above methods will definitely help to correct the situation. If we are talking about a wireless headset, then if there is constant noise, it is recommended to change the USB socket used as a receiver. Otherwise, all the tips listed above remain the same.
Extraneous noise in the headphones occasionally occurs due to virus infection. After curing the computer, the headset starts working properly. Fortunately, these kinds of events are not so frequent. And the main methods of dealing with the problem under study is to reinstall the driver, reduce and adjust the microphone. From now on, it’s clear how to remove noise in headphones on a computer.
