Sometimes, after buying or renting a Bluetooth earpiece, customers call our online store and say that the earpiece has stopped working. But for the most part, the wording is applicable: “I can't connect. If the same situation happened to you, do not panic. There are a number of nuances that you need to know and take into account when using a bluetooth earphone. Factors that make you feel that the device is not working may be: clogging of the speaker output with earwax, incorrect connection bluetooth headsets earpiece, incorrect placement of the earphone capsule in the ear, incorrect placement of the headset on the body, incorrect phone settings or incorrect battery placement. Let's consider each situation separately and understand how to act in this or that case.
Earwax clogging of the Bluetooth speaker output of the earpiece
There are situations when a person has connected and put on the headset correctly, but you still cannot hear anything in the Bluetooth earpiece. Most likely, the matter is not in the Bluetooth headset of the micro-earpiece. Most likely, due to non-compliance with the rules of hygiene, the speaker output is clogged with earwax. To date, there are already developments (for example, the company "Microtone"), which do not allow ear wax to clog speaker bluetooth micro-earphone: for an 11-mm earphone, the technology of "open sound labyrinth", for 6 and 9-mm earphones, the technology of a "closed sound labyrinth" (more about the types of micro-headphones). If you have an older earpiece that uses a felt filter to keep out speaker contamination, you will need to remove it and replace it with a new one. This is done with the help of available tools, for example, a needle for removing the battery.
You need:
1. Use a needle to remove the contaminated filter from the Bluetooth earpiece
2. Check availability earwax in or near dynamics
3. In case of dirt, carefully clean the speaker and the area around it, so as not to damage the speaker itself.
4. Replace the old with a new felt filter
5. Connect the Bluetooth headset of the micro-earphone and check how it works
Incorrect battery placement
As you already know, the earbud will not work without a battery. All Microtone bluetooth earphones use Camelion LR 521 batteries. Some 6 mm old-style earphones use 337 (SR416SW) batteries. And sometimes people are faced with the problem of incorrect placement of this battery in the earphone. Even from the course of school physics, we remember that you always need to observe the polarity of the battery (+/-). Accordingly, if you confuse the sides, then the earphone will not work ( detailed description micro headphone can be viewed). Correct battery placement:
For an 11 mm earpiece "+" outward, "-" inward, toward the speaker
For a 9 mm micro-earpiece "-" outward, + inward, to the earphone
For a 6 mm micro-earpiece "-" outward, "+" inward, to the earphone
An indication that the earphone is working is a slight noise that comes from the speaker after you insert the battery into the earphone connector. Based on this, we can say that the earpiece is in good working order and the problem is not at all in its performance.
Incorrect placement of the bluetooth headset on the body
In the catalog of the manufacturer's website microtone.com.ua there are 7 types of wireless bluetooth headsets for a micro-earphone. Three of them must be worn around your neck (Plantronics, Nokia, Plantronics MIC), since the loop that you put on your neck is an antenna that transmits the signal from the bluetooth headset to the earpiece. There are often times when a person has plugged in a headset but forgot to put it around his neck. Accordingly, in this case, he will not hear the interlocutor. Watch headset, like regular watch puts on the arm. The range of signal transmission of the Watch headset is approximately 20-40 cm. And, accordingly, without bringing your hand to your ear with the earpiece, you will not be able to hear anything either. Accordingly, you need to carefully familiarize yourself with the operating features of the bluetooth earphone headset and always place it correctly on your body.
Incorrect connection of the headset bluetooth earphone
When pairing with a headset for the first time, you need to find it in the list of active bluetooth devices and connect it to the phone. Since the headsets have the same name (PLT_MLXX, Nokia BH-108 or PLT_M20), you can simply confuse your device with the one you connected earlier. In this case, cancel pairing, delete all connected devices from the phone memory and start searching again. Now you will definitely connect your headset. Some phones suggest renaming the headset because the name has already been saved in the phone's memory.
Exposing the wrong phone settings
In this case, everything depends on the phone model. For some models, for example, for the iPhone, the sound, by default, may be transmitted not to the bluetooth headset of the micro-earpiece, but to the phone's speaker. To fix this, in the call menu, you need to change the sound source to the bluetooth headset of the micro-earphone. Below is an example for iPhone how to do it:
Similarly, this can be done, if necessary, in the call menu of any other brand of phone.
Incorrect placement of the earpiece bluetooth capsule in the ear
It is very important to place the bluetooth earpiece correctly in your ear. The earpiece speaker has a small diameter and narrow directivity. We recommend placing it in your ear exactly parallel to the ground. Because if you put it at the wrong angle, you can push the speaker output against the wall of the ear canal and partially or completely stop hearing your interlocutor. In order to correctly put the bluetooth micro-earphone in your ear, you can call your assistant before the exam and, at the time of your communication, align the earphone in your ear so that the sound volume is maximum.
1. Falling from a height of more than 1m can disable it.
2. The earpiece must not be pressed or squeezed
3. Ingress of moisture
4. After use, do not leave the battery in the earpiece, as this may cause oxidation of the contacts.
5. Do not bend the loop of the Bluetooth headset of the micro-earphone at an acute angle, as you can break the inductive winding of the wires.
If you follow everyone the above tips, then you are unlikely to have any difficulties when using wireless bluetooth earphone. For our part, we wish you only successful use of the device and are always ready to help you. If you cannot solve the problem on your own, please contact us.
Bluetooth is a wireless connection.
The task of the device is to connect different devices as well as transfer and exchange of files.
The adapter functions like a conventional radio receiver that is configured to send and receive signals. Just enabling the function will not be enough for the job.
For top level device detection is disabled in it. That is, in order for other opponents to see you, it must also be “activated”. Only then is the equipment ready for operation.

One of the main malfunctions in the adapter is that the bluetooth does not see the device. There are many reasons for this.
The most common:
- The software is not working properly.
- Discovery is not enabled on the device being searched.
- Big interference.
- The device to be connected is outside the range of the adapter.
Therefore, before proceeding to fix the problem, you need to figure out why the device does not see the device.

Sooner or later, everything needs adjustment. Bluetooth is no exception, which can also fail. What if the bluetooth on the laptop does not see the device? Let's solve this problem.
The adapter on a laptop may malfunction over time or immediately, on the first attempt to connect it. Find out the cause of the problem and proceed to troubleshoot it.
We will consider options for changing configurations using utilities and how to configure a device in BIOS.
Working utilities in a laptop

Interestingly, the utilities can toggle the state of the bluetooth. So, for example, "airplane mode" can turn it off altogether. For computers different brands these are different utilities, but there are many of them.
If after reinstalling windows systems if you do not want to install those utilities that the package provides for configuration, try downloading the necessary ones from the official support page of your laptop.
There are options when only using utilities you can change the configuration of the Bluetooth module.
It happens that it is possible to switch the state of the adapter only with their help (if there are original drivers).
BIOS settings
There are laptops in which you can configure the bluetooth functions in the BIOS system.
These include HP, Lenovo and others. By default, in the “Advanced” tab there is an item in which you can turn off and on the function.
Sometimes - in the System Configuration tab, in the Onboard Device Configuration, Wireless, Built-in Device Options sub-items. The Enabled value must be “enabled” in them.
If the BIOS does not have bookmarks with the word Bluetooth, you should try to switch the WLAN and Wireless items to the Enabled state.
Sometimes one tab is responsible for the active and inactive state of all wireless devices.
Bluetooth drivers: installation on a laptop
The reason for the adapter malfunction is quite common - the wrong drivers are installed or none at all.
How to recognize this problem in Device Manager:
- There is a yellow exclamation mark next to the word Bluetooth.
- There is "unknown equipment" on the list.
- In general, there are no similar subclauses.
- The Generic Bluetooth Adapter sits where Bluetooth should be.
Let's say you've updated the fixture drivers and the system reports that no more update is needed, but the module still doesn't work. This does not mean that the message is true. It's just that Windows has nothing more to offer you.
To solve this problem, you need to install the driver and see if it helps. Download it from the site that represents your laptop model.
You can find a site by scoring in search engine the phrase "laptop_model support". If desired driver no, use the most similar one.
In the case when something is already installed on your computer. You need to disconnect from the Internet and delete it.
Now you need to start installing the new software.
Often on the site, the representative offers not one, but several drivers for one version of the adapter.
In order not to be mistaken and choose the right one, you need to click in the device manager right click Misha on the word Bluetooth.
Then, go down to the sub-item "Properties" / "Information" and find the "Equipment ID". You will need the last line from the "Values" field.
Copy it and paste it into the search engine at devid.info. The system will sort the drivers that are most suitable.

If there are problems in the operation of the device on the phone. The very first thing to do is to determine the nature of the problem.
It is necessary to understand whether it is activated or not, does the problem arise when the device is turned on, or does it not work in principle?
Adapter won't turn on
If the device as a whole does not activate in any way and shows constant load, the fault of this incident is a hardware malfunction, a system malfunction, a virus in the phone, or a program with which there was a conflict is installed.
Try restarting your phone to fix the problem.
This action would be appropriate if the problem was lack of space due to overabundance temporary files or system glitch.
By doing this action, all your photos, songs and videos will be deleted. In order to preserve them, overwrite this data to another medium before resetting the settings.
In order to commit full reset settings, you should follow this algorithm of actions: "Settings" / "Reset settings".
If, after performing this option, the problem has not disappeared, then the device is simply broken. The situation can be resolved only with the help of a service organization for the repair of equipment.
In the case when it does not turn on in the newly purchased phone, change it under warranty.
The mobile does not see the bluetooth device, but the adapter turns on
If such a situation occurs, you need to check if Bluetooth is turned on.
Turn on Bluetooth
If yes, then you need to enable the device visibility mode and disable the "Discovery timeout" options. The device will now work in the correct mode.
Adapter turns on but no data transfer
In the case when in your mobile old version operating system, then there is no data transfer function in its BT-module.
To solve this problem, you need to update the OS - if you receive auto-updates on your phone. Or download bluetooth app Fle Transfer from Play Market.
It is very convenient to use bluetooth to exchange information between the phone and personal computer or to listen to music using the devil wired headphones.
But there are unpleasant situations when, after bluetooth updates, Windows 10 does not see the device. What to do in this case? Let's consider the situation in more detail.
Bluetooth device and driver status
First you need to determine if your bluetooth is still in place after the update? Are the drivers installed and how well do they work?
To check whether it is worth it on the computer, go to the "Control Panel", in the "Device Manager" section.
There, one of the sub-items should be "Bluetooth". If it is present, do you need to check if the drivers are installed on it? To do this, click on the name with the mouse and open the contents of the folder.
There must be an attachment in it. The main thing is that there would be no opposite exclamation mark... This means that all settings are correct and everything is installed.
There are times when a failure occurs and the required module is turned off. In this case, a black arrow is shown in the name fidgeting.
To change the settings to "enabled", you need to right-click on the name and activate the device.
If, nevertheless, the drivers are not installed, in the device manager, in the sub-item "other devices", " unknown device"Which, most of all, is your adapter.
To solve this problem, you need to update the drivers and register the path to them.
There is another option when in the device manager you will not see anything connected to bluetooth and to unknown devices.
You need to double-check and make sure that the adapter is generally present on the PC. If not, you should purchase it from a specialist store and install it. The simplest adapter looks like this:
What does Bluetooth look like on the toolbar?
If bluetooth is fully functional, present on your computer and even turned on, it should be displayed special badge on the toolbar.
Location - in the lower right corner, near the clock.
If it is absent, do not worry - it may simply be turned off. Auto-off is most likely inherent in laptops, since such programs consume an excessive amount of energy.
To activate it, you need to go to the menu on the toolbar and select the "Parameters" sub-item.
Then, go to the "Devices" section and select the "Bluetooth" sub-item.
If you are using a laptop, you need to find on the keyboard special key, with the help of which the module is switched on and off. In the case when you do not know where such a button is located, you can accidentally turn off the bluetooth all the time and puzzle over what is happening with the adapter.
Electronics malfunction sometimes occurs. Sometimes it's the fault hardware, sometimes the problem is software. But most often it is a combination of various factors.
If you connected the headphones to the charger and the indicator lights up, then everything works in normal operation and you just have to wait full charge battery.
If you connected the headphones to the charger and the indicator did not light up within a few minutes, the headphones may be out of order and you need to contact the nearest authorized service center for the repair of electronics.
Make sure the outlet you are connecting to Charger, working. If you connect USB earphone a cable to the computer, make sure that the USB port of the computer can work in charging mode, not all USB ports can transmit required level current to start charging the headphones. Typically USB ports on laptops that are capable of charging external devices, are indicated by characteristic pictograms in the form of a lightning bolt, an image of a battery or something similar. If when connected to one USB port nothing happens, try connecting to another or to another computer.
Your phone or computer cannot see your wireless headphones because they are turned off
Wireless headphones have a so-called "standby mode". It turns on when there is no active data transfer session to the headphones from the sound source. Those. you are not listening to music and the phone is not sending any sound to the headphones. At this moment, the headphones are still connected to the phone or computer, but they are in "sleep mode", power consumption is significantly reduced, but the battery is still consumed. And if you leave the headphones in this mode for several days, the battery will be completely discharged and they will stop working. Just charge your headphones and turn them on.
Pairing procedure
If you are connecting Bluetooth headphones to a phone or computer for the first time, you need to carry out the pairing procedure so that the phone and headphones transmit authentication codes to each other and start working in a pair. Without pairing the devices, your headphones will not work with the phone and the phone will not see the headphones in the list available devices... You need to put the headphones into pairing mode with a new device. Find out how to do this from the instructions below.
From the link above, you can familiarize yourself with detailed instructions initial pairing of devices. After carrying out this procedure, it will be enough for you to simply turn on the power of the headphones, after which they will automatic mode will connect to the phone within a few seconds.
Wireless headphones do not connect to the phone due to disabled Bluetooth on the phone
This is very commonplace reason, but you will be surprised how many people do not realize that it is necessary to turn on the Bluetooth module in the phone. Check, this is usually done in the panel quick access or in the "Settings" menu. Just find the "Bluetooth" item there and check if it works. 
In some phone models, the hide option is enabled by default Bluetooth phone from others Bluetooth devices, i.e. even if all devices are in good working order and work as needed, they will not see the phone and will not be able to receive a signal from it. Try to disable this option. In the screenshot above, I showed how it looks on my phone. Xiaomi- called "Visibility". As you can see, in my case, it is disabled, so all surrounding devices can see my phone and connect to it from using bluetooth... If I activate it, only previously paired devices can connect to the phone, and new wireless headphones will not see the phone and will not be able to connect to it.
Wireless headphones do not work with the phone due to different hardware versions of the Bluetooth module
V general case This should not be the case, Bluetooth is a backward compatible technology, i.e. Bluetooth 3.0, Bluetooth 4.0 and must be compatible with each other. But this is in theory, but in practice it may happen that due to software errors or a combination of hardware and software failures, the headphones and the phone may not see each other. This happens very rarely, but it does happen. Therefore, pay attention to what version of Bluetooth your phone and headphones have, if it is different, there may be a possibility of incompatibility between these two devices specifically.
In this case, try connecting the headphones to a different phone, preferably a different Bluetooth version... If the headphones work fine with another phone, then most likely you are faced with a rare problem of incompatibility between two specific gadgets. The only way to overcome the problem in this case is to replace the headphones or phone with another model.
Once again, I want to draw your attention to the fact that this is a very rare problem and should be considered only if you have tried all other ways to connect wireless headphones and they did not work.
Distance between sound source and wireless headphones is key for reliable signal reception
Make sure the audio source is within 10 meters of the wireless headphones. Please note that 10 meters is a reliable range of Bluetooth devices without obstacles such as walls, cars and trees. If you want to install a sound source in one room and listen to music in another, be prepared for the fact that serious interference may occur, up to a complete loss of signal. Bluetooth has a rather low radio signal strength and is therefore designed to operate over a very limited distance. But on the other hand, electricity is consumed in very moderate quantities.
Headphones broke
Wireless headphones are more expensive than their wired counterparts, so many people are trying to save money and buy inexpensive wireless models... remember, that free cheese does not happen, and if you bought very cheap Bluetooth headphones, you can become a victim of the manufacturer's total savings on every element of the headphones, from hardware filling to software... The likelihood of breakage increases significantly.
If your headphones don't work with your phone, make sure they are in good working order at all. Try turning them on. If they do not turn on, put it on charge. If they do not charge and do not turn on, the verdict is obvious, they are broken. If they are charging but do not turn on, try entering them into pairing mode by holding the power button for a long time, depending on the model, you may need to hold the button for up to 10 seconds. If after that the headphones do not turn on and the phone does not see them, most likely they are broken and need to be repaired or replaced.
Another reason for the failure of wireless headphones is poor quality built-in battery. You bought headphones, listened to them for a couple of weeks, and now they began to hold a charge for just a few tens of minutes instead of the promised few hours. If this happens, this is a factory defect and you need to try to return the headphones to the manufacturer. Or, if there is such a desire, to repair it under warranty.
Another type of hardware failure is constant interference during sound reproduction even if the sound source is located a few centimeters from the headphones. If, even at a very close distance from the source, the sound is reproduced in interference or is interrupted, this is a breakdown of the transmitting Bluetooth module... Return the headphones to the manufacturer or have them repaired, depending on the situation.
Water - main enemy wireless headphones. Unless the packaging or instructions clearly state that they are protected against moisture or splash, try not to expose the headphones to water, and even walking in light rain can be fatal to the electronic filling. It is for this reason that I highly discourage using regular headphones during hard physical training. During training, you actively sweat, and sweat is much more aggressive than ordinary water affects electronic components... If at least one drop gets inside the headphones, there can be serious problems up to the complete breakdown of the device. You can only play sports with headphones that are sweat and moisture resistant.
If the tips in this article did not help you - describe your problem in the comments. I will try to help with advice.
After purchasing a Bluetooth headset, many users face certain difficulties in pairing it with mobile phone and further customization. A similar problem due to the fact that not all models of wireless headphones are able to work with music files... Therefore, we will consider how to set up a bluetooth headset on Android so that it can be used not only to make calls, but also to listen to audio.
Initial configuration of the Bluetooth module
Before you start using the hands-free, the first time you connect it to a smartphone, you will need to pair two devices: Android and a Bluetooth headset. For this, it is necessary that on mobile device the opportunity was foreseen wireless transmission information on the radio channel.
Initial configuration of a Bluetooth headset is performed as follows:
After successful pairing, the recognized headset will appear in the Connected Devices section. 
Now, in order for the sound when making calls to go not to the speaker of the smartphone, but to the Bluetooth headset, in its settings, you need to check the item "Sound during a call". Checking the box next to "Multimedia Sound" will allow you to listen to all multimedia files hands-free. 
Play music via bluetooth headset
In some wireless headphones, the manufacturer does not provide the ability to broadcast a multimedia stream. Such products are used only for conversation during telephone calls. Such restrictions are laid down at the software level, so they can be bypassed with the help of special software.
One of the programs that allows you to expand the functionality of your wireless headset is Mono Bluetooth
... It works as follows:
By activating media redirection via Mono Bluetooth, your earphone will always be in active state and play sounds from audio and video players, games, system applications etc. This drains the charge on the headset's power supply. Therefore, if unnecessary this program better off.
Bluetooth headset connection problems after Android update
After upgrading the software, many owners of smartphones and tablets encounter malfunctions of certain modules on mobile device... If updated android completely refuses to work with a wireless earphone, it can be argued that the problem is programmatic nature... However, solving it is sometimes quite difficult. This is due to the fact that the radio module does not have its own settings - they are sewn into the system and closed from external interference. Therefore, you will not be able to update or roll back the parameters of the Bluetooth module separately.
The following steps will help to restore the bluetooth to work after the Android upgrade.
Wireless headphones make it much easier to use a smartphone during a call when a person's hands are busy. Any malfunction this device is a problem, so if your phone doesn't see your bluetooth headset, it's worth checking out how to diagnose and troubleshoot problems.
There are several reasons why wireless headphones stop functioning:
- The headset is simply not turned on or is already paired with another gadget.
- The device has run out of battery.
- The sync function is disabled in the settings.
- There are technical problems with the gadget.
The smartphone does not see the headset if the devices are incompatible, so before buying it, you need to find out which models can be used for a particular brand.
Visual information about diagnostic methods is reflected in the video:
How do I fix the problem?
To figure out why the phone does not find a bluetooth headset, you need to exclude some shortcomings:
- Make sure the batteries in both gadgets are charged.
- Make sure the accessory is not being used by another device.
- Check if the synchronization of the smartphone with the headset is activated.
- Eliminate technical problems.
Before connecting wireless headset, you need to make sure that Bluetooth is turned on in the device, and then reboot the accessory. When you turn on the headphones for the first time, they go into automatic connection for about 3 minutes, and for further pairing, you need to do the following:
- Bring the headset to the device and search for available devices by going to "Settings", then - "Connections" and "Bluetooth".
- When the gadget sees bluetooth headphones, click on their name and pair.
- Usually the password is 0000, 1111 or 1234.
Many users cannot connect a bluetooth headset to the phone due to a malfunction of the latter. How to find out which gadget has the problem:
- Connect the communication device to another gadget. If the pairing is successful, it means that the malfunction should be looked for in the device.
- Connect another headset to the device via bluetooth. The lack of contact indicates a problem with it.
Wireless accessories are now in great demand, because they make life much easier for people: they allow you to drive a car, work and do other things without using your hands. Most often, pairing problems can be solved on their own, but if after repair the situation remains the same, you should take the headset and smartphone to the service.
Device compatibility
Among all the reasons, it is worth highlighting the use different versions bluetooth, as a result of which pairing is impossible. For example, a wireless device is equipped with bluetooth v.5, and your cell phone supports a set of protocols for version 3.
If ordinary wired headphones were purchased for talking and listening to music, the problems may lie in them:
- Broken wire. Visually, this is imperceptible, but at a certain position of the cord, a sound will appear, which indicates a problem with it.
- Clogged contacts. For diagnostics, it is enough to direct a beam of light there and see if there is a plaque there. If there is, it can be cleaned with rubbing alcohol and a piece of cotton wool over the needle, but be careful.
When it seems that the problem is with the headphones with wires, try connecting them to another gadget. If the sound is reproduced, you need to look for flaws in your smartphone.
Technical problems with your phone
If you can determine that the headset is fully functional, you need to make sure of the following:
- The phone connector contacts are OK. To do this, turn off the device by holding the power button for about 10-15 seconds, then pull out the memory card and SIM card. Next, you should remove the panels, unscrew all the bolts and inspect the contacts in the corresponding socket.
- Contacts are not oxidized, short circuit did not have. The check is performed in the way presented above.
Sometimes a problem in the phone occurs due to a blockage random access memory, and here's the best way to do a factory reset:
- We go into the phone settings, find "Restore and reset" or just "Reset".
- We select "Reset all parameters to default values".
It should be remembered that after Hard reset all data, including photos and videos, will be deleted, so it is necessary to copy them to a PC or SD card in advance.
If no other reasons unrelated to the smartphone were found, it is necessary to inspect the headset itself and read the instructions that came with it. Perhaps the point is in the banal incompatibility of devices, or the contacts in the headphones have moved away, which is extremely rare.
All models of headphones are in most cases universal and suitable for a wide range of gadgets, however, it will never be superfluous to make sure that they are compatible with a specific brand of device before purchasing.
Conclusion
If the phone does not see the Bluetooth headset, this makes it impossible to use it. To resolve the situation and continue using the wireless communication device, you need to know what causes the problem and how to fix it yourself.
