Many music lovers use headphones to listen to music. The same applies to the sound from the TV. There are two reasons for this:
1. There is a complete immersion in the music: you are not distracted by outside noise. And the quality of playback in headphones is often better than in music speakers. Of course, this applies to home equipment - serious acoustics simply do not fit in the conditions of the room.
2. You are not disturbing those around you. Perhaps someone in the room is resting, or wants to watch a second TV. Headphones help to separate comfort zones, and prevent conflicts with those around you.
It would seem that the problem does not need to be discussed - buy headphones, plug them into the TV, and enjoy a private immersion in the world of sounds. However, there are several problems:
- Not all TV receivers have an appropriate connector.
- Most headphones are equipped with a connecting cable not longer than 1.5 meters. And sitting at such a distance (being "tethered" by the cable to the TV) is uncomfortable, and unhealthy.
Content:
Connect headphones to your TV the normal way.
Look around the back (some models have the ability to connect on the front) of your TV receiver, or better yet, study the operating instructions. If there is a standard connection - deal with the technical side of the issue.
Standard for the connection of headphones is the so-called "jack", that is a pin jack with a diameter of 3.5 mm.

The connector consists of 3 cylindrical information pins: "ground", "left channel", "right channel".
If you have a headset with a microphone and not the usual headphones, there are two possible ways to arrange the connectors.
Separate plugs for the microphone and headphones. In this case, you connect only one plug to the TV.
There are headsets with an extended plug, for 4 pins. It is better not to use this connector to connect to the TV. Theoretically, the maintenance contact for the microphone is not involved, but it can be short-circuited to "ground". The equipment may fail.
This does not mean that you need to buy a new set of headphones. There are OEM adapters - splitters.
With their help, the information channel for headphones is allocated, and you use a separate plug.
Let's go back to the connectors on the TV. They are usually marked with a headphone icon, or the abbreviation H/P OUT:
It is necessary to look carefully at the marking. Connectors of this standard (3.5mm jack) are used for different purposes. If you see markings like: "AUDIO IN RGB/DVI", or "COMPONENT IN" - on no account connect headphones to them.
Next is the software part of the question. The headphone jack standard provides for automatic disconnection of the signal going to the TV speakers. That is, you plug in the headphones, and the loud sound from the TV disappears.
Note: Before disconnecting the headphones, remember to mute the sound. Usually when you listen to headphones, you turn up the volume.
There are some models of TV receivers that do not have this feature. Nothing happens after plugging in the jack. You need to go into the TV settings menu, and make a switch in the "sound output" section.
If your TV does not have a headphone jack
Unfortunately, many modern models do not provide the ability to connect headphones. There is a simple solution:
As a rule, any TV receiver has audio outputs for connecting external acoustics. These are in the form of RCA connectors (so-called "tunnels").
This is nothing more than a line output. It is not provided with a powerful amplifier, but for confident listening to audio information in headphones, it will be enough. To connect to the jack type "3.5", an adapter is used.
If the audio output is designed to connect 5:1 speakers, there will be 5 or 6 "tulip" jacks on the TV panel. In this case, the adapter is connected to the "FRONT L/R" connectors.
To disable the signal going out to the TV's loudspeakers, you must make a switch in the "sound output" menu.
Another "spare" option is a universal SCART connector
Present in almost every TV model.
Both audio inputs and outputs are present on this jack. The level is low: there is no power amplifier. As in the case of RCA jacks for external acoustics, the audibility in headphones is sufficient. When connecting to a SCART-type jack, you must also switch the sound in the TV menu.
Since there are no adapters from SCART to "jack", you need to install such a strip, which has two modes: "IN" and "OUT".
Switch to "OUT" mode and connect the headphones through the adapter from RCA to "jack".
If the cord in the headphones is short.
Of course, you can buy a second headphone with a 4 or 6 meter cable. But there is a more economical way: buy an extension cord.
No comment is needed. In any case, a long cord is a certain inconvenience. It can be snagged by housemates or pets. And lying on the couch with a pair of wires is not very comfortable.
The ideal solution is wireless headphones.
It also solves the problem of a TV without a headphone jack.
What kind of headphones will work with your TV receiver?
There are Smart TV models that have a Bluetooth module. However, its presence is not a guarantee of compatibility with wireless headphones. It is necessary to look at the technical specifications, and make sure that the function "output sound to a Bluetooth device" is present. You turn on this mode, and power the headphones. The receiver finds the new device - and you receive sound over the "air line".
If there is no function - you will have to look for headphones with a transmitting module. It looks like a normal USB flash drive.
Of course, your TV receiver must support such devices (again, look at the manual). The transmitter can use Bluetooth technology, Wi-Fi, or infrared signal. In the TV menu you switch on "sound output to USB" mode and your household will enjoy the silence.
Note: Not all TV models "know" how to transmit sound via USB. If you can connect a wireless mouse or keyboard to it, it does not guarantee compatibility with headphones.
If none of the above methods are not suitable, the only thing left is to upgrade the TV. You have to open up the cabinet, and solder a lead to the input of the low frequency amplifier (which you will build into the cabinet panel). But this is a job for an experienced electronic technician, in addition, this is followed by the deprivation of warranty.

It would seem that the problem doesn't need to be discussed - buy headphones, plug them into the TV, and enjoy a private immersion in a world of sounds. However, there are several problems:
Not all television receivers have an appropriate jack for connection.
Most headphones are equipped with a connecting cable no longer than 1.5 meters. And sitting at that distance (being "tethered" by the cable to the TV set) is uncomfortable, and unhealthy.
We solve the issues as they come up:
1.Connect the headphones to the TV the normal way.
Examine the back wall (some models have the ability to connect to the front panel) of your TV receiver, or better yet, study the instruction manual. If there is a standard connection - deal with the technical side of the issue.
The standard plug for headphones is a so-called "jack", that is, a pin jack with a diameter of 3.5 mm.

scart. The common headphone output remains free. We sacrifice stereo in favor of mono, but we get a good volume and lack of background. In series with the headphones you can put a resistor up to 1 kohm (I have 680 ohms) for a TV-safe connection. Paradox, but it works. With normal connection the volume is weak because of the uncoordinated high impedance of the signal source and low impedance of the headphones. Connecting the left and right earphone phones in series doubles the resistance. Aesthetic option - for installation we use the scart-rca adapter with the installation of an additional jack "mother jack 3.5. And in conclusion: I started watching movies, before 10 years I did not understand anything because of bad sound.
