Currently it is proposed to choose from many species of various Blutuses of headphones, headset and speakers receiving sound through this protocol. Very often, when buying inexpensive headphones, there are problems with sound quality, namely stuttering sound and its delay. There are several ways to solve this problem ...
The main problem of stuttering Blutuz headphones is the quality of their manufacture and incompatibility of standards. The problem may be in a low-sensitive antenna and the power of the processor built-in to the device. And, accordingly, no power grip can be on the transmitting device: computer, tablet, telephone and Bluetooth module inserted in USB port PC, as well as the incompatibility of Bluetooth version.
It is still noticed that in the room the headphones work well, and on the street there is constantly interrupted. In the room where there are walls close, the signal is reflected from the walls and falls into the receiver of the wireless headset and everything works fine. Where there are no walls, the sound is lost.
It is noted that the same headphones on one smartphone work normally, and on the other they are stuttering. And it happens so that everything was fine, but after installation new program Or update the application, the sound is synchronized. It is also observed when the screen is turned off mobile device Or when switching the phone to the locked mode.
Particularly often occurring sound when installing, deleting or copy files from a flash drive to a USB flash drive. Since the system resources are used at this moment. All this worsens the sound quality in headphones. If this happens, then it must be borne in mind that the power of the processor lacks the sound and transmission to the Blutuz protocol.
Clean, loud sound without wires.
Chief Council, before buying a Blutuz headset, check the quality of playing it, as they say "without departing from the box office", immediately in the store. If this is not possible, keep the check and packing the goods, to return it back to the point of sale.
What if the product is not possible to return to the store?
How to solve sound stuttering in Bluetooth headphones?
1. If you have a PC and USB, the Bloom module is inserted into the rear port of the computer. Move the USB Bluetooth on the front side of the PC. Better to buy a USB hub on the wire, lift it higher and stack the USB Bluetooth module into it. If the Blutuz adapter is old, then it is better to change it to a newer and modern one.
Updating Driver Blutuz 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 have to start searching drivers windows tools. For this, select "Update".
If it does not help, then you must try to put different versions of the drivers and check, somehow can earn.
When synchronizing with a PC, the Bluetooth headphone models may have compatibility problems with Windows drivers.
3. Outside on the street to exclude interruptions in music playback, put your smartphone as close as possible to headphones. Shoot your smartphone from pockets in your pocket, and the higher the headphones, the better. Or put it in the upper, inner pocket jacket. Do not use headphones in the cold.
4. With the player settings or in the settings of the audio device on the PC, lower the quality of the playback of the audio stream, i.e. If you listen to music in 320kbbit / s or more, try the sound no more than 128kbbit / s. Audio MP3 files must be recorded with a low bit rate.
If you have a laptop with weak speakers And when playing the next volume of the volume of the built-in speakers, it is not enough for a comfortable view, you can use tips on increasing the volume on a laptop or telephone.

5. Make the BT mode on the transmitting device "visible to all". In this mode, the system loads less processor.
6. The devices are closer to each other for a few seconds or put the sound playing in the player or youtube pause, it is necessary to synchronize devices. To complete sound synchronization, you may need a few seconds.
7.The Android 6.0 in the settings there is an item: "application permissions", in it "Transmission via Bluetooth". Here you need to remove all the ticks, except for the "volume". Here we click: "Changing settings" and select the item "Do not disable".
8. Android Android OS can be dispersed through special programs Type: Setcpu, Tasker, Antutu CPU, TEGRAK, Overclock and others. Changing OS operation parameters is made in the "Performance" section. You need to change the following values: Government in "Perfomance", Scheduler in "CFQ". Even advise such a solution: Installing Kernel Adiutor C CPU Governor to Ondemand (+ "Apply On Boot" for convenience).
9. You can use the load on the system using a special software. There is such a DROIDWALL program that can control Internet access each application OS android. What to reduce the load on the processor, prohibit not necessary in this moment Time applications access to the Internet. You can do it through the program menu.
10. Put the antenna in the headphone housing or columns Bloom. If you remove the housing cover, then the feet should be a kite-shaped path. To this track, the craftsmen solder a piece of copper wire centimeter 4-5. After that, the signal quality rises and the sound stops stuttering.

11. The load of the processor on the PC can also be disabling the microphone on the Bloom headset. To do this, you need to go into the control panel \u003d\u003e sound \u003d\u003e record \u003d\u003e microphone \u003d\u003e properties \u003d\u003e Listen \u003d\u003e Remove the checkbox with "Listen to this device" And restart the computer.
12. Performances from other devices strongly affect the quality of the compound. If the wireless column or SAB is located next to the router, a TV, a computer, microwave and other sources of radio interference, then it / it must be moved away.
13. The trouble-charged battery is the reason for the lack of power of the processor of the device Blutuz.
14. The unaware models of Blutuz headsets may not be compatible with new smartphones and vice versa. This is the main reason for the instability and stuttering music. Therefore, before buying a wireless device, you must always check whether these two mobile devices will be well available.
More information about the Bluetooth protocol can be read in the article on Habrahabr.ru. There is analyzed the process of loss of signal with screenshots and graphs.
Analysis of human body impact on the transmission power of the audio data via Bluetooth protocol.
In the picture, it is shown that from the dump it is seen, the BitPool value for this portion of traffic is 48, but it cost me to close the way from the laptop to the column, as the BitPool value began to decline, accompanied by interrupts and clicks.

After the BitPool value settled at level 30, the clicks are disappeared, the playback of the audio has become more continuous. Everything indicated that the codec was performed by auto-adjustment, noting the degradation of the quality of the signal.
But did I really contribute such a significant attenuation? Well, time to look at the indication schedule for the power level of the received signal.
Despite the technological achievements, Bluetooth headphones still suffer from some unpleasant problems.
We looked at the most common problems of Bluetooth headphones and found several solutions.
My smartphone can not find Bluetooth headphones
You want to connect headphones to your smartphone, but for some reason headphones are not displayed in the list of Bluetooth devices? Here is a list how to solve the problem:
- Check if you enable Bluetooth connection on your phone. Surprisingly just skip.
- Check whether your headphones are compatible with your device and OS. If you are using iPhone, it should work at least on iOS 7, which originally supports Bluetooth Smart Ready. If you are on Android, make sure it works at least on Android 4.3.
- Make sure your smartphone and headphones are close to each other when you want to connect them. The best way Provide a good connection, it is closer to the devices at least 50 cm from each other.
- Check the manufacturer recommended by the manufacturer. Not all bluetooth headphones will connect to your phone in the same way; Sometimes it is just as easy as just turning on the headphones, in other cases it is a little more difficult. To avoid problems with the connection of your device, carefully read all the detailed steps about what you should do.
- Try turning off and turn it on again. This is an old method, but let's take the truth in the eye - sometimes it really works.
- Turn off or remove all interference. Perhaps for some reason your headphones are trying to connect to another device, and not to your smartphone.
- Get off from the Wi-Fi router. Perhaps yours wi-Fi router Uses the same spectrum as headphones, and thus causes some interference.
My Bluetooth headphones are periodically disconnected
There is nothing more disappointing than listening to music when suddenly your bluetooth headphones are simply disconnected. Sometimes the Bluetooth connection is completely disconnected and makes you connect again, at another time it will disappear for a few seconds before it connects. These problems are easy to solve:
- Stay within the range of your headphones and smartphones. It is very easy to move away from the smartphone and bluetooth will not work.
- Remove all unnecessary Bluetooth connections. It is possible that your smartphone is "overloaded" by the number of attempts to connect to it.
- Make sure your Bluetooth headset is charged. Bluetooth headphones tend to a periodic disconnection with a low battery charge level.
- Try to turn off the headphones, and then connect them again with your smartphone.
The connection between my headphones and smartphone works unstable
It also often happens that when you are trying to connect your headphones and smartphone together, you either get an error message, or the dispenser process will work unstable - without actual remediation. The simplest solution here:
- Delete all unused or unnecessary Bluetooth connections. Some devices begin to hang if there are too many devices in the Bluetooth connections list.
If it does not help, you can try any of the other ways that we have already indicated.
I hear noise in Bluetooth headphones
Despite the long way, Bluetooth technology is still susceptible to interference, such as static or crackling noises when you listen to music.
- First, you must disable or turn off other unused bluetooth devices in this district.
- If static will not disappear, try to reboot your headphones (you can easily understand this by contacting the manufacturer's site).
- Turn on the media player, then turn off the headphones for 30 seconds, and then connect them again.
- Reduce the distance between your smartphone and headphones, as it also helps to reduce (or even decide) any problems with noise.
All these are proven methods for solving some of the most unpleasant Bluetooth problems, but this is not full list. If none of these troubleshooting methods work, it is better to contact the manufacturer.
Have you tried any of these methods to troubleshoot problems with Bluetooth's own devices?
Get more and more distribution. Pushing the manufacturers of smartphones themselves, eliminating the 3.5-millimeter audio jack from the new models. Everything would be fine if not one "but". The sound quality in wireless headphones is most often medium or even low. And the user may encounter a sound latency in Bluetooth headphones. What caused these two troubles? Surely large companies still can't come up with a normal method of transmitting sound through air?
If with the average quality of sound, it is quite possible to terms, then when the music is interrupted - it quickly displays. These second or even semi-acean pauses make it back to wired headphones, connecting an accessory at least through the adapter.
Unfortunately, to find out the exact causes of the micropause almost impossible. The fact is that Bluetooth is very different from the same Wi-Fi - this method of transmitting the signal is less standardized, and there is often not enough power to be "Blue Zeub". If Wi-Fi quietly penetrates even through the walls of the house, then the Bluetooth signal can also interfere with the lining of the jacket. That is, try to pull the smartphone from the inner pocket - it is possible that the sync cleanliness will significantly improve.
Unfortunately, he derses sound in Bluetooth headphones and then when the accessory is right next to the smartphone. This indicates the low compatibility of the chip in the headset with the module located in the phone. It is possible that the latter is used by some unsuitable codec. After all, if you did not know, no analogue is transmitted by air, and digital sound. Headphones still need to be decrypted, only after that playing. If the electronics in the product is not the most powerful, then from time to time, micropauses can really occur.
If the purchase of Bluetooth headphones is only to be, then be sure to read technical characteristics Accessories. Try to choose such an instance that has supported precisely those profiles that are built into the Bluetooth of your smartphone. It is also desirable that the version of the "blue tooth" was also the same. In particular, now many smartphones have on board Bluetooth 4.0 - a similar version should have a wireless headset.
If the headphones are connected to the computer, you can "fold" with the settings of music players to remove the audio interrupt. Change the sound output from the DirectSound on Waveout - sometimes it can help. Unfortunately, in the smartphones, the Bluetooth-connections settings are noticeably less, so it is impossible to favor experiments here.
Bad sound
The quality of sound depends on several factors. Basically, this parameter affects the Bluetooth version. In each fresh version, some new profiles and technologies appear. For example, now smartphones and wireless headsets Gradually go to the APTX HD codec, providing sound transmission in hardly CD quality. If you are not limited to financial resources, it is better to purchase an accessory with support for this codec. But do not forget that then the smartphone will need the appropriate.
The sound quality depends on which music files are reproduced. Pay attention to the MP3 Music Bitrate - the best sound will be with files with a 320 Kbps parameter. The real music lovers must go to files with a lower compression degree - for example, on FLAC. Weighing such music will be more, but when it is saved to these compositions, too high or too low frequencies. However, an increased bit rate can lead to micropauses - Bluetooth data transfer rate is strongly limited.
Of course, first of all, the purity of sound depends on the design of the headphones themselves. Stupid to expect good sound From the simplest "plugs" for 2000 rubles. Want to enjoy music without using wired connection? Then you will have to fork out for an expensive headset from the well-known manufacturer. Difficult to choose from? Focus on the selection.
Conclusion
Alas, but modern wireless technologyserving to drive sound, do not let somehow play the settings. If some problems arise, it most often talks about poor compatibility of headphones and smartphones. And in the case of not good sound, it is necessary to blame the underdeveloped design of the headset (or a weak chip). That is why when choosing wireless headphones Do not save.
Despite the ease of operation, sometimes we still face definite problems, such as extraneous sounds, similar to hissing and wheezing, because of which the sound quality is generally deteriorating significantly. To eliminate this problem, need to know possible reasons Her appearance.
It is important to know that, despite the entire elementality of this device, a person who has not had to faced problems in his work and eliminate them, this problem may seem very serious.
In order to understand where the hiss in the headphones arises, you need to understand a little about how they are arranged. Pay attention to the fact that you constantly hear hissing sounds or only periodically.
One of the reasons why this problem may occur is incorrectly connecting headphones, or rather, the choice of incorrect settings. In addition, if the headphones are not new, check if the contacts are working with which you connect them.

Noise in headphones caused by faulty sound card
Such a part, as a sound card, has the most direct impact on how high-quality melody is reproduced by equipment. If the item is faulty, personal Computer can not accurate sound signalsWhat is why the normal sound is complemented by hissing, a crash, the sound seems to be "rehearsed" and "jumps". In this situation, only replacing the faulty item will help, and then the sound will no longer be accompanied by outsiders.
Faulty wires
For the correct operation of the headphones and the correct transmission of sounds often corresponds to the manufacturer of the model.
It should be known that there are two types of headphones: wireless and with wire. Outsided soundsAs a rule, appear in models running through a cable connected by a plug. If the copper cable live is damaged or stretched, noise noise and jump-shaped sound interruptions.
The damaged wire often leads to noise in headphones on the iPhone. This is due to the fact that the cable material is thin and flexible, it is easy to break. The conductor with damage sends the sound card to incorrect characteristics of the signals, and this is reflected on the sound. How to eliminate the hoarse of headphones? This can be done, removing the overshadled or bare area of \u200b\u200bthe wire, as a last resort, will have to buy new fittings.
Broken usb input
Incorrect sound may occur after connecting other gadgets to a USB connector. Call the problem can mouse, or defective keyboard. In this case, by pressing the key, you will hear clicks. There are quite objective reasons why it happens.
When the information is transmitted, the load on the PC is raised. To reduce it, you need to do the following:
1. Switch the plug to another port.
2. You can also purchase a splitter and repair old connectors for connecting.
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 emerging problems. As a result, USB connectors one after another come to unsuitability, and only one remains, in which the splitter connects and it is all the load that it becomes the reason for its increase.

Noise from working with mouse
When you make a scrolling page with the mouse, sometimes you can also notice noise, sometimes they are simply unbearable. Solution of the problem will be the replacement of the mouse, switching the mouse to the neighboring USB port or installation of external sound card.
No grounding sockets
This problem is not often, but still arises, interfering with the normal operation of headphones. The absence of grounding can also cause a cod, clicks and other noise in headphones. If you have already checked the headphones and did not find any problems, check the sockets to which the computer is connected.
This nuance concerns only stationary computers, Laptop cards are usually ground at the stage of their production.
When you use headphones connected to a laptop, incorrect sounds are most likely provoked by internal malfunctions of the device. Should not tighten with the appeal to service centerwhere your device is propagated for troubleshooting.
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 occur in the work of the main sound source. Rarely, but still occur the driver errors. Program errors and malfunctions operating system cause interference in the form of noise and cod.
The problem can be detected by checking the device using the connection of various headsets. If their work is equally unacceptable - unpleasant sounds will be heard in all headphones, it means that the problem is hiding in the device driver.
If you are used to listening to very high volume music, you can also notice the appearance of hissing and cod. As a rule, it happens if you purchase inexpensive headphones.
There is not enough powerful power supply - another reason for extraneous noise at the sound of headphones (such a problem is sometimes found at the owners of laptops, which have not yet understood with all its features). Eliminate this problem simply using the following prompts.
On your laptop, go to the "Control Panel", then in "System and Security" and, finally, in "Power Supply", and select High Performance Mode. At the end of the setup, check the sound quality in headphones.
The world stepped into a wireless era. Keyboards and mice, data transmission, Internet access - everything has already left the cables for a long time. However, there are still certain things that literally keep us in this terrible world of wires. And besides the most obvious - for example, charger, remain and less noticeable, but far from less important accessories are headphones. After all, you will agree, not everyone falls on the temper every time to think about where and how to "push" the wire only to go out. And when sports about the headphones, it is generally better not to remember. Why so there - did you never annoy you that they should be removed to stand because of the computer? Therefore, for many, the issue of buying wireless headphones is quite acute. It would seem that everything for this is - at the moment this market is already saturated enough to find a suitable option. But, unfortunately, there are a certain number of problems. After all, in essence, Bluetooth headphones did not make significant high-quality jerks from the very moment of their appearance.
But on a certain day, such a question became before me. Being confident in the fact that the current year did the technology, I quickly chose my gadget - Jabra Halo 2. [Lyrical retreat]: Yes, we can say that 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 deprived of all the following flaws. Moreover, even Jabra Halo 2 budget can not be called in no way - I will remind you that for the same one thousand hryvnia you can buy quite serious wired headphones [End of lyrical retreat]. And after almost a year since the start of operation, it is ready to tell about all aspects of life with Bluetooth middle class headphones.
The first minus surfaced almost immediately - as soon as the phone turns out in pocket jeans, the signal begins to get lost. We had to put the phone in the pocket of the jacket, the jacket, or in the bag (however, it turned out that the connection is much better in the right pocket of jeans, but it did not solve it completely). And in general, the interruption of sound is the most common problem. Interference can catch you literally at any time, and they are so nasty that you start to unwittingly turn the phone in your pocket in the search for "optimal position." Moreover, it happens that the environment affects the environment - near the local stadium, for example, interference is observed almost always. Also, the gap will pursue you in the first minute or two after connecting to the device.
Second problem - sound quality. Yes, in fact, Bluetooth headphones sound perfectly - but with a connected wire. On the wireless connection, they are suitable except for listening to podcasts, radio, watching rollers with YouTube and communicating with friends. Music connoisseurs will be increditious to turn the nose (and fairly), although not particularly arrogant users (like me) and others will be satisfied.
And it is logical that a little lame speed of work. From the sound itself until its playback in headphones, there is some time within a second. And from the very first day, the user will notice that before to start playing the sound, the headphones will turn on the barely noticeable noise (on the background of the music it is completely lost), and when playback is over - this noise will disappear, while with a sufficiently sharp click, which is high Volume can noticeably hit the ears. However, it is possible to get used enough to this.
And at least these three minuses are already predetermined by the fate of wireless headphones. There is no practical meaning in them. It can be seen that this direction is gradually developing, but specifically at the moment - this is a waste of money. It seems that the market exists in order for it to be at all - and the user still finds. Believe me, freedom from the wires are not worth all the problems described above. Although there are positive moments with such headphones, but my advice to you: either buy expensive Bluetooth headphones, or take good and wired.
