If you have carefully observed your headphones, you must know that the two headphones are printed with the letters "L" and "R", and they all know that they represent Left and Right headphones, and they will distinguish between left and right headphones when they are used.

     But do you know why earphones are divided?

     What kind of experience is it if you wear it backwards? What effect will it have 

on the sound quality and the feeling of wearing? Today, let's work together to raise 

posture.

1. In line with the principle of music recording

     First of all, it is because the music is recorded using two microphones according 

to the left and right channels, in order to ensure the high reducibility of the sound 

field, the headset as a transmission carrier also needs two channels, that is, we 

usually say stereo effect.

     That is to say, the headset must have the corresponding left and right channels, 

and be worn in the correct direction, so that the ear can receive the corresponding 

music.

2. Create stereo effect

     People have two ears, and the left and right ears can hear different sounds to 

restore the real scene of the sound, and can distinguish space, orientation and 

level.

     For example, the sound is on the left side, our human ear must feel the left ear first, we can judge the location of the sound source, the simplest example is the "listening to the location" of the chicken game, can quickly determine what the enemy is in, is approaching or leaving.

     The left and right channels can form a stereo system, forming a surround sound effect, when you listen to music such as symphony, you can feel the strength and distance of various instruments, and you can also experience the voice and background sound through stereo when watching movies, and completely integrate into the movie scene. 

3 Different ear structure

     The structure of our left and right ears is not the same, the design of headphones must match the structure of the ear, such as the current popular in-ear headphones to adapt to the structure of the human ear, so that users have a better wearing experience, will be special design for the different structure of the left and right ears, with different shapes to make users more comfortable to wear.

     In order to wear more comfortable, the left and right ears will have the corresponding fine tuning, recognize the right and left wear, not only can better fit the ear, the sound will be clearer.

What's it like to wear it backwards?

     If the left and right earphones are worn backwards, the most common problem is that the ears will feel uncomfortable, and even cause pain, because the earphones are designed based on different structures of the left and right ears, and the ears will not fit when worn backwards, which very affects the wearing experience and is easier to fall.

     In addition, the left and right headphones represent the right and left channels, wearing the reverse will cause auditory confusion, can not effectively restore the sound of the scene, the original left sound is transmitted to the right ear, resulting in the opposite direction.

     Unexpectedly, a small design of headphones originally contains so many principles, in order to give yourself a better audio experience, when wearing headphones remember to recognize "L" and "R"!
