* **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 and disadvantages
#### Advantages
1. **Reduce external noise**: In-ear headphones can effectively isolate external noise and provide a quiet listening environment due to their closed design.
2. **Improve sound quality**: In-ear headphones can produce higher volume and better bass effects, while reducing sound leakage and increasing the performance of music details.
3. **Physical noise reduction effect is good**: In-ear headphones have a significant physical noise reduction effect, suitable for use in noisy environments, such as public transportation, gyms, etc.
#### Disadvantages
1. **May damage the eardrum**: Because in-ear headphones can produce shocking bass, long-term use may cause damage to the eardrum.
2. **Wearing comfort**: Wearing in-ear headphones for a long time may bring pressure to the ears, especially for users who are more sensitive to the ear canal.
3. * * health risks * *: regular use of in-ear headphones also easy to make the external ear canal skin cuticle swelling, blocking hair follicles, become a hotbed of bacterial growth, increase the risk of ear infection.
