Why should the headphones be divided into “L” and “R”?

Here will tell you

In our life, did you find somewhere in the headphones will be printed with

two letters "L" and "R"?

Most people know the "L" and "R" on the headphones represent the "left"

and "right" of the earbuds.

But why should the earphones distinguish between "left" and "right"?

(Not just because people have the left and right ears so simple)

01 To comply with the recording of music

When recording music, it mainly uses two microphones to record in

accordance with the left and right channels,

Ensure high reproducibility of playback

“L” is the left channel, which is the abbreviation of English letter "Left"

The ear will receive the sound of the corresponding left channel

“R” is the right channel, which is the abbreviation of the English letter "Right"

The ear will receive the sound of the corresponding right channel

So should distinguish between “L” and “R”

Music-compliant recording, it can make the ear listen to the left and right channels better. 

02 In order to create the stereo effect

People use two left and right ears to distinguish the difference

between left and right channels in space, direction and level, 

Allows the listener based on the recorded audio to identify the location of

the sound and restore the sense of space

Good stereo, the listener can distinguish the direction of the sound

The process of moving with the sound source

So distinguish between L and R

Can create a stereo effect

Let the ears better enjoy the sense of music space

03 In order to adapt to the structure of the left and right ears

Because the structure of the left and right ears are different

So wearing it backwards will cause discomfort to the ears

Wearing it for a long time may also cause ear pain

So a good earphone design will be based on

The difference between the left and right ear structure to create

The purpose is to make the wearer

Have a more comfortable use

04 Need for game identification

For gamers

Many times, the right and left ears

Will play a decisive role in the outcome of the game

Because many games need to listen

Keep track of the enemy's position at any time

The result of wearing headphones

Will be clearly heard the footsteps of the enemy on the left

Are ready to pose to kill each other

But found that he was killed

Teammates may have mistakenly thought that you gave the head deliberately

and so

In order not to let yourself be the "pig teammate" of ears and partners

Make sure you wear the "L" and "R" right!
