What is the difference between right and left headphones?

In some situations, it is very important to understand the location of the left and right audio channels. For example, to watch a movie or play a game with clear positioning of sound sources. Where you heard a rustling sound in a thriller, or from which side the enemy is firing at you in a game. The design of gadgets is sometimes such that wearing them incorrectly will also be uncomfortable. And modern musical compositions will not sound right if you mix up the right and left headphones. So today we’ll figure out how to check this.

Determining headphone channels by appearance

It is better to start checking the right-left headphones with a thorough inspection. After all, the manufacturer always leaves designations. True, there is no one specific place for marking, and it can be located anywhere on the body.

I think everyone knows what the designation looks like, but for the sake of order I’ll still remind you:

1. The right one is marked with the letter "R", and sometimes with the full word "right". If color positioning is used, then there will be a red icon on the body - a dot, a line. For example, in headphones with a detachable cable, such marks correspond to both the plug and the connector.
2. Left is denoted by the letter “L” or the word “left”. If in color, then green or blue.

By the way, letters are sometimes not noticeable externally, but they can be found by touch. The icons are located on the outside, front or back, at the junction with the cable.

Interesting fact! Different sounds in the ears create the same effect of stereo or surround 3D sound. Such effects help you hear complex compositions not as some kind of sound mush, but in a very detailed and realistic way, as if you were sitting in front of an orchestra.

Why is it important to wear headphones correctly (left and right)

Stereo sound is not a repetition of the same sounds in both ears, but two different channels, so the sound seems surround. When listening to music, for example, ambient music, which contains sophisticated effects, the difference is noticeable if the headphones are mixed up.

In movies and video games, sounds from the left side of the screen go to the left ear, and sounds from the right side go to the right ear. Disorientation occurs if the crash does not come from where the explosion occurred on the screen, and the impression of the special effects is lost.

Reference! In games, it is very important to navigate by sounds. The gameplay result will be disappointing if the enemy is on the right, but you can hear him on the left.

Helpful advice: if there is no marking, it has been erased, or you are simply too lazy to think for a long time about which earphone is which, a simple life hack will help: buy replacement earplugs (ear pads) of a different color and replace one. For example, the right one will remain white and the left one will be black. It's difficult to confuse.

How to determine if there are no inscriptions

Unfortunately, often the markings are applied only with paint, then over time the letters are simply erased, and it will no longer be possible to find the left and right earbuds this way. Therefore, I will list other ways to check headphones for the right and left channels:

1. If the device is wired, then, as a rule, a microphone is located at the wire connection. And if you put your ears on correctly, the microphone hole will be on the outside.
2. Some models have different wire lengths on the left and right. So the right one will be shorter, since the microphone in the headset is usually made on this side.

1. Sometimes the designation on the body appears in the form of convex dots. One, two or three, which can be felt with your finger on the left body.
2. Anatomically designed models will be comfortable only if the ears are positioned correctly. Since the shape of the case, the curves are created for positional wearing.
3. You can check the headphones by turning them off, then the sound on the right will disappear faster.
4. The bass is more pronounced on the left, but the vocals and highs are louder on the right.
5. There are risks in devices with a detachable cable. And when connected, they will match in location and color.

Determining the left and right channel of headphones using a music player

I decided to add a piece of humor to this article and show how to change the balance between channels using the example of the long-known but now forgotten WinAmp player.

So, run WinMap of any version available to you. In the standard interface you will find a slider (highlighted in the screenshot) that is responsible for channel balance. In my case, I completely switched the music playback to the right channel. If you move the slider to the far right position and the sound comes from the right headphones, everything is fine. If not, look for a problem in the headphone connection.

Methods of checking online, as well as using special programs and applications

1. Online test on special sites. Where you can not only decide on left-right in headphones, but also evaluate the sound of different frequencies, the presence of background and the overall quality of audio playback.
2. There is a freely available video on YouTube for positioning sound by channel. It's called "Left and Right Earphone Detection". https://www.youtube.com/watch?v=RXVyvCsDi6E
3. If you do not have access to YouTube, you can check the channels at https://www.audiocheck.net/audiotests_stereo.php.
4. In Windows, open audio playback devices. To do this, right-click on the speaker icon in the tray and select “Playback devices”. Then select the connected device (indicated by a green checkmark), right-click on it again and go to “set up speakers.” Next, simply select the right or left channel and listen to where the sound will come from.

5. Some audio or video players contain a special control that determines the balance of volume on the right and left. Checking the headphones - move the slider left and right, the sound will become stronger in one ear and muffled in the other.
6. For smartphones, you can download any audio application. These can also be proprietary programs from the ear manufacturer with an equalizer and other gadgets to reveal their full potential. And there, in the settings, you can find the positioning of the sound on the left and right channels.

Checking stereo sound right and left using a test track

It's easier to check stereo using a music track. To do this, find music on the Internet. Professional studio recording is also suitable. Such a test is not exact, but it will allow you to understand whether the sound is satisfactory or the device is working.

When downloading audio, you should make sure that the player through which you will listen to the track is of high quality. After all, a bad signal source compresses and deforms the sound, producing poor results.

Those who prefer not to watch the video, but to test their headphones in another way, should turn to the test tracks. The most popular entries are:

1. There's a knock on the door. First there is a knock in the right speaker, after which the sound moves to the left channel. Listening will quickly reveal which one is performing worse or not functioning at all.

1. Frequencies 20 Hz – 10 kHz. Testing involves sending the signal evenly to both speakers. The absence of problems in the left and right speakers is understood by the identical sound on both sides.

If there is a delay in sound on the left or right, it is heard off-center, then it will be easy to determine whether the speaker is faulty. To fix the problem, you should contact specialists who also check by serial number or try to fix the problem yourself.

You can determine a possible defect if you download a file that reproduces the knock and frequency. There are options with phrases in the audio file. It sounds when turned on and identifies the channel.

Simultaneous sound from both sides indicates a problem with the jack. Most often, breakdowns occur in areas where the signal wiring of the channels is soldered.

If you can’t test using a track, you can use a PC program. It is used to perform the procedure for positioning sounds in headphones.

To check for imbalance between channels and volume level, turn on the track in Mono mode, adjust the volume and check the audio recordings.

They also select the appropriate sound, start the song and listen to it. If the key shifts, the channel imbalance is obvious. Defective models should produce rich and realistic sound.

To identify problems with overtones, a monophonic sweep top is used. Mechanical difficulties in the low frequency region arise when the membrane is touched by something or when there are cracks in the membrane. This is accompanied by the appearance of resonance at specific levels. Rattling at low frequencies can be heard if a hair gets on the membrane.

Music tracks play low frequencies first, gradually moving towards high frequencies. The sound of one channel louder than another indicates a problem.

Test tracks allow you to independently evaluate the sound quality of the software player, check the characteristic distortions from the influence of the OS system mixer and other effects.

How to swap channels in a sound card driver

Sometimes, after checking the headphones, it turns out that the left and right do not correspond to the channels that the sound card sees. The reasons are incorrect wiring at the factory, crooked drivers, or the filling of the device, which distributes sound. But what if the correct positioning of the ears on the right and left is extremely important? There are at least 2 ways to fix this:

1. Update sound card drivers. Automatic updates don't always work. Look up the name of your sound card in Device Manager or using the AIDA program, for example. Go to the manufacturer's official website, download the latest drivers and install them manually. Don't forget to restart your PC. The situation may improve.
2. In cases where the culprit is not crooked software, but an incorrectly assembled device, you can use the special Equalizer APO utility, which will save you from resoldering contacts.

How to change the left and right channels after checking the headphones using Equalizer APO:

• After downloading and installing the program, go to Program Files (my computer, local drive C);
• Open the Equalizer APO folder;
• Next is the config folder;
• Create a text file and call it any name;
• Open the file and copy the following inscription “Copy: L=RR=L” there;
• Close all tabs;
• Launch Equalizer APO;
• There will be a line in the window with the map settings. They need to be deleted by clicking on the minus icon;
• Now click on the plus, then control, and then Include (Include Configuration File);
• The new line with the settings will contain an error warning - No file selected. Select the folder icon, and then find the folder you created earlier;
• Run and save the changes with the Power button next to the new configuration line;
• Check the headphones for left and right.

Attention! Changes made using the utility affect all playback devices, not just headphones. The columns will also change places. But you can disable the configuration at any time.

Other ways to check where headphones are left and right

Although most devices on the market have appropriate channel markings, some may not. In addition, over time, the designation may be erased. However, you shouldn’t rush to the store to buy a new accessory. There are a variety of ways to help determine the correct location of the channels.

To do this you will need to do the following:

1. Carefully feel the device body. There are usually several miniature bumps on the left cup. It is worth keeping in mind that this method is not suitable for checking overhead, monitor or full-size models.
2. Measure the length of the wire. The cable coming from the right bowl is usually longer than the cable from the left.
3. Microphone. If this is a headset, then its design includes a microphone. It is always attached to the body of the right cup. Therefore, if you put on the headphones correctly, the headset will be in front of your face.

4. Plug color. The plugs are painted in the color corresponding to the channel. The right one will be pink, and the left one will be blue or green.
5. Checking using audio files. Put on the accessory and turn on any music or movie. After this, with a sharp movement, pull the plug out of the socket of the laptop or system unit. The sound always disappears on the right earbud first. In addition, you can include an audio file with rich low frequencies. Bass sounds better on the left channel.
