Wireless headphones are convenient, practical and compact device to transmit audio that works wirelessly (hence the name). But why does one headset require a wired connection, while another can work at a distance, and what are its advantages and disadvantages? All answers about how to use wireless headphones in the article below.
What is Bluetooth and how does it work?
It is Bluetooth that allows wireless headphones to work without the use of forever torn wires. This is a technology based on the transfer of data between devices by exchanging information using radio waves.
"Bluetooth" is a radio frequency standard patented over 20 years ago, named after the King of Denmark, who ruled in the 900s. This is a spectrum of frequencies that other radio devices do not use - the range from 2.400 to 2.4835 GHz. In addition, this is a set of rules in the form of a protocol that normalizes the interaction of devices connected to each other.
Bluetooth appeared in response to the technology of data transmission via the infrared port, which was popular at that time, the disadvantage of the transmission method was the high requirements for transmitters - they had to be placed in direct line of sight to the receivers and on short distance from them. "Bluetooth" can even work through a wall and any surface that is capable of transmitting a radio signal.
Functioning wireless technology through special piconets. There are active and passive devices. The first connects to the second and transmits information in the form of bits. In this case, the transfer rate can reach up to 3 Mbps. Since Bluetooth uses low-power waves, data transmission does not drain the device's battery at all and uses a minimum of charge.
Bluetooth range. How far can wireless headphones work from a signal source
The key problem of this technology is the presence of many devices equipped with radio modules. Because of this, there may be interference in operation when third-party equipment is accidentally connected to the transmitter. But the developers of Bluetooth did everything possible to prevent the occurrence of such a problem - they reduced the Bluetooth range as much as possible and activated frequency hopping.
As a result, you will not be able to listen to music through a wireless earphone if it is further than 10 meters. And so that an outside device does not accidentally interfere with your data transmission channel, the transmitter changes its frequency every second. Even if the frequencies match, it will be a short break in communication that you will not have time to notice.
How to pair devices via Bluetooth?
Not all electronics are equipped with this technology, and if the device has Bluetooth, it is not certain that it will be suitable for pairing with headphones. The developers of this data transfer method, in order to avoid interference, made it so that each device has its own set of protocols with which they can work.
The easiest way to connect devices is when both of them have Bluetooth. Then it is enough to activate this function in both devices and connect through the active gadget to the passive one for data transfer. If Bluetooth is not available in the device, then you can connect a special adapter, which will act as a removable radio module.
Wireless headphones sometimes come with an adapter and a receiver. In this case, you only need to connect the transmitter to the equipment that transmits sound, and insert the receiver into the headphones. True, this is far from being true for any equipment, and depending on the configuration of the adapter, you can connect it to a USB connector or to an audio output, for example, of a music center.
What are the profiles of wireless headphones?
How to use wireless bluetooth headphones and get the best sound quality? Not all wireless headphones perform equally well. This is because they use different codecs and profiles in their work. That is, they are based different technologies, although they work using the same networks. There are 3 main profiles with which the headphones function:
- Headset Profile - the most basic profile that was created to transmit sound in two directions: so that you can listen to music, and. But the attempt was not entirely successful - the quality of the transmitted sound is very low - at best it is 64 Kb / s.
- Handsfree Profile is a more advanced profile, much like its predecessor. The sound quality is better, but you still won't be able to listen to music. But for talking through the Handsfree Profile headphones is very well suited.
- advanced audio Distribution Profile is the best profile for connecting headphones with other devices. Although it compresses the sound (and it won't work any other way, because Bluetooth technology is very limited), the sound quality remains about the same as if you were listening to music through wired headphones.
There is a so-called Bluetooth Profile, which describes the functionality of this wireless communication. In particular, the A2DP (Advanced Audio Distribution Profile) profile determines how well the audio will be transmitted (mono or stereo) when using Bluetooth.
In turn, A2DP supports several codecs that encrypt the original digital audio signal for transmission over Bluetooth. All Bluetooth-enabled devices support the so-called basic codecs (SBC), but may also support additional codecs such as Apt-X, AAC, MP3, etc. They provide better audio quality than SBCs and Apt-X is the most advanced audio codec available today.
The basic SBC codec uses a limited frequency range of the transmitted signal with a sharp drop in the frequency response above 14 kHz, so it is not suitable for high-quality music listening. getting worse.
The Apt-X codec uses ADPCM audio processing technology, which is a lossless data compression with support for 16 and 24-bit processing, and a dynamic range width of up to 120 dB. In fact, the differences between it and MP3/AAC codecs are the same as between audio files compressed in MP3/WMA and FLAC/WAV. At the same time, the Apt-X codec can transmit audio encoded in MP3 and AAC without additional processing, without degrading its quality.
How to connect wireless headphones to your phone, computer or tablet?
As a rule, in the package with the purchased headphones there are detailed instructions. If it was not at hand, then you will have to do the following:
- Set up Bluetooth on the transmitting device.
- Connect to headphones.
- Start audio transmission.
In the Bluetooth phone, it is very easy to set up. Just go to settings and enable wireless network bluetooth. Next is activated automatic search available devices. Check that the headphones are turned on (usually, they are equipped with lights or indicators that allow you to quickly verify that the network is working). To turn on the headphones, find a special button on their case. When connecting, a password will be requested - enter "0000" or look for a different PIN on the headphone manufacturer's box.
It will be more difficult to connect to the headphones through a computer, since stationary PCs do not have a radio module. You will have to buy a separate Bluetooth adapter. Plug it in via the USB hole, insert the driver disk, and then through the "Toolbox" in " network adapters» Find your wireless network and activate it. To connect with headphones you will need to download special program. Each headphone has its own, so ask about it in the instructions or call the manufacturer.
Wireless headphones are connected to the tablet in the same way as to a smartphone. Please note that when you connect for the first time, the device will be found in the search, but after connecting it will disappear, since synchronization will take place automatically.
How to improve the sound quality of wireless headphones?
In order for the sound not to hurt your ears, you need to achieve the maximum accuracy of the audio transmission through the headphones. To do this, use the Advanced Audio Distribution profile. To configure it, you need to install the appropriate drivers - you can try installing Bluesoleil different versions, just keep in mind that they will work differently.
If you turn on the headset on the computer, do not let the headphones initiate the connection, otherwise they will do everything in their own way. Make sure that the sound is not spoiled by neighboring devices operating at a similar frequency. For example, it can be a router (Wi-Fi can take one or more of the 79 Bluetooth channels). Also, do not place the transmitter and receiver behind thick walls, as this will shorten the Bluetooth range.
And be careful not to use the headphones for too long, especially for mono devices. If you use a mono earpiece in one ear every day, it will degrade over time. Keep an eye on the transmitter volume so that a sharp grinding or interruption of the radio frequency does not deafen you or deafen your hearing!
What to do if the device does not see the Bluetooth headset?
The reason may be as follows:
- The headphones have run out of batteries.
- you have not enabled device sync;
- did not turn on the headphones.
Sometimes the phone is deactivated automatic synchronization, so you have to connect to the headphones manually every time. On a computer, you already have to do this - each time you connect to the headset through a special program. Make sure the headphones are working before diving into the transmitter settings.
How to use bluetooth headset? Despite the fact that such devices have been in wide demand for a long time, the number of users is still growing every day. This is not strange, because wireless HandsFree is very convenient, even for listening to music at home.
But before moving on to the question of how to use Bluetooth headset, you should understand what it is all about? After all, this is the basis that will allow you to better understand the principle of operation of such equipment.
Description and features of Bluetooth technology: Video
What is a wireless headset
It is worth noting that there are a huge variety of different types, types and options for such accessories:
- Stereo or mono.
- Supporting different standards (2.1, 3.0, 4.0 and so on).
- FROM additional features, for example, the ability to connect to two phones at once.
- Vacuum, liners and overhead, and much more.
To answer the question of how to properly wear a Bluetooth headset, you should start from what type it is. For example, on-ear headphones are worn on the head and fixed with a bow. If a we are talking about vacuum, they are inserted into the ear canal, as well as regular earplugs.
The main rule is that you should be comfortable in them. In addition, you should hear the interlocutor well when talking.
How to connect a headset to a phone or tablet
There is nothing terrible and complicated here. As a rule, instructions are included with the headphones. But in any case, everything happens according to the same principle. Turn on bluetooth adapter on a smartphone. Now on the headset, find the power button and press it. Hold the button until the indicator flashes blue and red (color may vary depending on the model).
If you do not have an indicator light, then just hold the power button for about 15-20 seconds. In this way, you will turn on the discovery feature so that the phone can find and connect to the equipment. Now go to your Bluetooth settings on your smartphone.
Here you will see a list available connections. Select a headset and click Connect.

Charging the headphone battery
Since Bluetooth headphones require additional power to operate the adapter, as well as to play sound, it is logical to assume that there is a battery inside. Hence another question, how to charge a Bluetooth headset?
Immediately it should be noted that not every model has the ability to charge. In other words, some headphones run on conventional batteries that cannot be recharged. In this case, the interface for connecting charging is simply not provided and you certain moments need to change the power supply.
In addition, there are also such options, complete with which the docking station is attached. She is also a charger.
However, these options are more expensive. In the bulk, however, Hands Free has a standard interface for connecting charging. He can be different types. Since the vast majority of smartphones and tablets nowadays use a micro USB connector, it is recommended to choose a headset with the same interface. This will allow you to charge all devices with one power supply.
Listening to music on a wireless headset
Often users ask the question, is it possible to listen to music through a Bluetooth headset. There really is no single answer. The fact is that some models support the Headset and A2DP functions. These features allow you to listen to music through a wireless headset, but are typically only available on stereo headphones.
If you are using a budget option with one speaker, then in this case, you will not be able to listen to music in the usual way. But, do not rush to get upset. You can download and install the "Mono Bluetooth Router" program. The application allows you to use any type of Hands Free to listen to music. This is the answer to the question how to listen to music through a Bluetooth headset.
Fm radio is a separate issue. The answer to the question of how to listen to the radio through a Bluetooth headset is just like listening to music. The main thing is that your smartphone or tablet has an FM receiver function. It is worth noting that certain models of headphones have a built-in receiver, so you don't even need to connect them to your phone to listen to FM stations.
Wireless Bluetooth headphones are comfortable, convenient and the ability to always stay in touch, even if your hands are busy. All you have to do is choose the right one Bluetooth headset and connect it. It is important to know that you need a Bluetooth adapter to connect wireless headphones to your computer. How it looks and how to choose it, read in this article.
Why the phone does not see the Bluetooth headset: Video
More recently, in the noughties, with the phrase “wireless headphones”, the imagination drew something completely different from what it is now. In this newfangled category at that time, quite massive monitor headphones were most often located, receiving a signal from the docking station. She, in turn, was powered from the outlet and connected to the sound source using an aux cable. Together, a massive structure was formed, which even at home looked unaesthetic and took up a lot of space, not to mention the fact that someone wanted to take it outdoors or on a trip.
Since that time, technology has stepped far forward and the term "wireless headphones" means something light, almost weightless, with which it is convenient to play sports or walk to work in the morning.
All wireless headphones can be divided into 2 large categories. The first includes models where there are no wires at all. Detached earbuds stow away in the battery case when not in use, preventing them from getting lost and prolonging the time battery life. The second includes devices in which the left and right headphones are connected by a wire. It most often houses the battery and the playback control panel. One of these models will be discussed today.
JBL has a lot of experience in creating audio accessories. In their model range have headsets different levels, the E25BT model occupies a niche of budget devices. The price in different stores ranges from 2590 to 3490 rubles.
Headphones are supplied in a dense cardboard package and, in addition to the headset itself, the kit comes with interchangeable ear pads of two sizes, short USB cable- micro-USB, a storage case and a clothespin that is held on by the battery and clings to the collar of the clothes so that the headphones are held evenly, I will talk about it in more detail, but a little later.
Appearance
Most models of this form factor look similar, and this one is no exception. The left and right earphones are connected by a wire that is dense to the touch, on which the battery pack and the control panel are located in the center on the right side. With it, you can turn the device on and off, stop / continue playback, select the next or previous song. The remote has a microphone for using the headset function. In general, the model is designed in a serious style, not striking, but it does not look cheap either.
Sound
The E25BT sound good, but nothing more. The main emphasis is on low frequencies, however, after an hour and a half you get used to it and high and medium gain their features. Fans of electronic music, I'm sure, will be pleased. If you look in the direction of something heavier, then the vocal parts and high notes of the guitars will not sound very correct. Classical lovers will note the unnatural predominance of bass instruments over the rest. For those who don’t, it’s important whether the headphones are with a wire or not, but you need the most good sound I would recommend the Sennheiser CX-3.00. The price is the same, but they sound better.
I will say a little about the microphone, the interlocutor almost never understood what I was trying to tell him. Even when I was in a quiet room.
Peculiarities
In the E25BT, I can note several pleasant technical features. For example, to find out the battery level, you need to connect the headphones to your smartphone and next to the battery level indicator of your mobile device, the headset charge will be displayed.
The headphones also store 2 devices in memory for fast switching between them. First you need to connect to the first one, then hold the middle key and “+” simultaneously for three seconds and select “JBL E25BT” on the second device. After that, reconnection from one to another will happen quite quickly.
Quality
I've got portable speaker, JBL Pulse, which has served faithfully almost every day for four years. Partly because of this, I looked towards JBL when choosing wireless headphones. However, what was my disappointment when, just three months after buying the E25BT, serious problems began with them.
I was walking down the street listening to something from System Of A Down when one song was over and the next one was about to start. However, after a second pause between songs, nothing happened. Moreover, the headphones stopped responding to any actions on my part, and a lone blue indicator. The headset did not respond to any pressing, and I could not even reboot it. Everything was back to normal when I put the device on charge. After that, a similar refusal to work as it should was repeated 1-2 times a day and for some reason it was on the road, and since I don’t carry an external battery, I spent a good half of the way without my favorite songs. Presumably, the problem lies in the battery, but it is doubtful to repair or replace it on such headphones.
At the same time, the clothespin fell apart into small parts, so I apologize for the fact that the photos in which it is visible are not mine, but taken from the network. It is not convenient to use the E25 BT without a clothespin, because due to the asymmetric weight of the design, the headphones constantly move to the right side.
I also note that the places for attaching the wires to the battery and the control panel look very weak. It feels like the cable is about to rub against the plastic.
You can say: "Marriage happens everywhere, don't you think that everyone is like that?" I read reviews and comments from other owners and an unusually high percentage of them experienced the same problems.
Let's move on to the pros and cons, and then I will voice the conclusion.
Strict design
Acceptable sound
Good battery life
Convenient attachment to clothes (until it breaks)
Weak microphone
Battery problems
Build quality
A short-lived clip on clothes, without which use is inconvenient.
JBL E25 BT would suit many, due to ease of use, good sound and pleasant appearance However, if you don’t want to constantly experience inconvenience with glitches while listening to your favorite music, faced with marriage, I would not recommend taking this model as wireless headphones.

If you don't have a microphone, you can take your headphones to connect to an audio device and use them as a microphone. The methods of this connection may depend on the type of audio devices you are using.
When connecting earpieces (read more) to a device that is designed to work with a dynamic type of microphone, then you do not need any matching circuit. If the instrument has a 3.5mm microphone jack, you can simply plug in headphones without making any changes. You will need to speak to the right side, so the left one will be shorted inside the nest.
In order to use both emitters as a microphone, you must cut off the plug from them, and then attach another monophonic one to them. If you only have stereo on hand, you must connect the common contact to the middle one. The “silver” or “gold” wires must be connected together and connected to the common contact of the plug. You must connect the green or blue wire to the red or orange, after which it must be connected to the far contact.
There are also devices that are designed to connect a dynamic microphone that is equipped with other types of jacks. An example of this is most karaoke systems that have a 6.3 mm jack, and tape recorders are equipped with five-pin connectors. You have to cut off the plug from the headphones, replace it and connect it to a 6.3 mm jack using the method described above. If the player has two jacks, then you can use two pairs of headphones through which four people can sing at the same time.
To connect headphones instead of a microphone to a tape recorder with a five-pin socket (DIN, or ONTS-VG), gold or silver wires must be connected together and connected to the middle pin of the plug, and green or blue together with orange or red on the right side. If this microphone does not work, you must swap the last pair of wires to the left side.
Sound cards not designed to work with a dynamic microphone. If you try to directly connect a microphone, you will get a barely audible sound. In order to amplify the signal, you must use microphone amplifier ready-made or homemade. However, we must not forget that without correction frequency characteristics even the best amplifiers will give out a loud, but booming sound. Therefore, use an amplifier that is equipped with corrective circuits. Excellent results can be achieved using an amplifier board from a conventional music player. Its gain is very strong and you may need to install an attenuator.
When you decide to purchase a gadget such as Bluetooth wireless headphones or headphones with headset capabilities, in order to get rid of annoying wires, you should know certain features of working with them. Unlike conventional headphones, Bluetooth headphones are a gadget with its own control system, connection and use features.
Therefore, so that you can choose the model that is optimal in terms of capabilities and most comfortable for you, check out the typical recommendations on how to use Bluetooth headphones. Please note that the possibilities different models may vary significantly, so please read carefully before purchasing. specifications and controls of the gadget you like.

Basic Functions of Wireless Headphone Controls
Bluetooth headphones usually contain at least 3 hardware buttons, the functions of which can be combined depending on the options for pressing and holding the button. Here are the features that are typical for most gadgets:
- Inclusion. In most models, this is a combined button that turns the headset on and off by holding it for a long time (several seconds). There are models with a separate power button, including in the form of a microswitch.
- Volume "+" and volume "-" allow you to adjust the power of the built-in amplifier. Often they combine the function of rewinding to the next and previous tracks when listening to music.
- Play/pause start button. Used to control the player. Often combined with the functions of turning on / off, receiving a call, calling the last number, turning on voice dialing.
- Buttons for switching rewind to the next and previous track are used to control the player.
- A separate button for accepting a call, it also serves to end the conversation and dial the last number.
- A hardware microphone switch can also be found on some models of Bluetooth headphones with headset functions.
- Button for switching the signal source, for example, to FM radio or an installed SD card.
Obviously, the more functions assigned to one gadget button, the less quickly you can manage it. Therefore, the presence of the controls you need should be given special attention when choosing a specific model.
Connecting Bluetooth Headphones
Connecting Bluetooth wireless headphones to mobile devices, laptops and personal computers has several distinctive features. You should be aware of them, especially if you plan to use the headphones in conjunction with different devices.
Connecting wireless headphones with a microphone to a computer via bluetooth 
Connecting Bluetooth headphones to mobile devices
Connecting Bluetooth headphones to a smartphone or tablet is the easiest way. To do this, the first time you need to turn on the headphones, the Bluetooth receiver is in mobile device and search for available hardware. After that, you need to pair the found device. Then, if necessary, configure the parameters of data transfer protocols. For subsequent connections, simply turn on the headphones and Bluetooth on your smartphone or tablet. The connection should complete automatically.
Connecting Bluetooth headphones to a laptop
Most modern laptops include a Bluetooth module, so you don’t need to buy anything extra. As preconditions for the ability to connect Bluetooth headphones, you can name the included hardware or software Bluetooth module in the laptop and correctly installed drivers bluetooth.
You should look for them on the disk or on the manufacturer's website for the one you have installed. operating system. Selecting and connecting to a device is done through the computer's device management interface, which differs depending on the operating system.
If there is no Bluetooth module or it cannot be configured due to the lack of drivers, the problem should be solved in the same way as connecting wireless headphones to a personal computer.
Connecting Bluetooth headphones to a personal computer
AT personal computer there is no standard Bluetooth module, so you will have to buy it, install it in one of the free USB connectors and configure the drivers. If you initially plan to actively use Bluetooth headphones with a computer, you might want to consider buying headphones with a base that connects to your computer with a standard USB cable.
Such a model will cost more, but you are guaranteed to save yourself from possible difficulties with setting. In addition, the range of such systems is usually greater.
How to charge Bluetooth headphones
The need to periodically charge Bluetooth headphones is a kind of payment for freedom from wires. Charging is usually done using a standard USB cable that comes with the kit. It is recommended immediately after purchase to discharge the headphones before turning off, and then fully charge them. You can repeat 2-3 full charge-discharge cycles.
The built-in controller will not allow you to discharge the headphones to a deep discharge state and recharge it. However, it is recommended not to leave a fully charged gadget plugged in for a long time.
If you do not plan to use the headphones for some time, charge them first. You can find out the operating time of Bluetooth headphones after a full battery charge from the instructions. However, keep in mind that the average operating time in the main modes is shown there, which may differ depending on the mode of use of the headphones.
