What are the advantage and disadvantage of in-ear earphone and over-ear noise-cancelling headphones?
In-ear earphones, also known as ear canal earphones and in-ear earplugs, are generally of the moving iron type with good resolution. Headphones used inside the human hearing organ are designed to seal against the user's ear canal when in use.
Advantage
1. The physical noise reduction effect is good, the external noise and other interference are small, and the details of the song can be heard at a relatively low volume in a noisy environment.
2. To achieve the most intimate contact with the ear, most of the in-ear type adopts a closed design, and the space between the ear canal and the headphone diaphragm is closed, which greatly reduces sound leakage.
3. This type of earphone increases the texture and volume of low frequency, and increases the performance of music details. At present, low-end in-ear earplugs mostly use to increase the texture and volume of low frequency, while high-end in-ear earplugs mostly use to increase the performance of music details.
Shortcoming
1. For some people, wearing in-ear earplugs is a painful thing, and it is not suitable for ears such as otitis media;
2. Using in-ear earplugs may scratch the ear canal;
3. It is used by many people; it is easy to cross-infect some bacteria;
4. The principle of sound production is unnatural (the sound is produced in the ear canal through a small tube).
Headphones are different from in-ear earbuds and are a type of earphones worn on the head. Generally, it is a moving coil type, which consists of two parts, a signal transmitter and an earphone with a signal receiving and amplifying device (usually a moving coil type).
