In-ear headphones, also known as canal headphones, in-ear plugs or in-ear monitors (IEM), are earphones designed to be inserted inside the human ear canal. The following is a detailed introduction to in-ear headphones:

 

### 1. Definition and Classification

 

* **Definition**: In-ear headphones are small headphones that are inserted into the ear canal through a colloidal plug to form a sealed hearing environment.

* **Classification**: In-ear headphones are mainly divided into wired and wireless types, both of which are part of In-Ear-Monitor-System (IEMS).

 

### 2. working principle

 

The working principle of in-ear headphones is mainly to generate vibration through the moving coil drive unit, thereby generating sound. The moving coil drive unit usually consists of a coil, a magnet and a diaphragm. When an electric current is passed through the coil, the magnet generates a magnetic field, which generates a force that causes the diaphragm to vibrate, which in turn produces sound.

 

### 3. Advantages

 

1. **Reduce external noise**: In-ear headphones are designed to be close to the ear canal, which can effectively isolate external noise and provide a quiet listening environment, especially suitable for use in noisy environments, such as public transportation, gyms, etc.

2. **Good sound quality**: Because in-ear headphones can form a sealed environment, they can provide higher volume and better bass effect, rich sound details, and are suitable for users who pursue high-fidelity sound quality and immersive listening experience.

3. **Reduce sound leakage**: A closed environment for in-ear headphones greatly reduces sound leakage, making the sound more concentrated and clear.

 

### 4. Disadvantages

 

1. * * May damage eardrum * *: In-ear earplugs can get more shocking bass due to less leakage, but this deliberate increase in a certain frequency band of sound signals may cause greater damage to the ear.

2. **Wearing comfort**: Long-term wearing of in-ear headphones may cause pressure on the ear canal and increase the risk of ear canal infection, especially for users who are more sensitive to the ear canal, they may feel uncomfortable.

3. **Safety hazards**: Wearing in-ear headphones when walking or riding outdoors can easily ignore the changes of surrounding vehicles, and there are certain safety hazards.

### 6. purchase suggestions

 

1. **Consider the use of scenarios**: according to the use of individual scenarios to choose the appropriate type of headphones, such as noisy environment can give priority to in-ear headphones.

2. **Pay attention to sound quality performance**: For users who pursue high-fidelity sound quality and immersive listening experience, they can choose in-ear headphones equipped with high quality audio units and audio technologies.

3. **Focus on comfort**: Users who wear headphones for a long time should pay attention to the comfort design of the headphones to avoid oppression of the ear canal.
