Basic classification of headsets:

1. Classification according to use:

Portable headphones: Earplugs can be classified as portable, and their fundamental feature is that they are lightweight.

Monitoring headphones: The monitoring referred to here refers to music monitoring. Headphones that can provide accurate sound reproduction can be used for monitoring purposes, and their fundamental feature is accurate reproduction. It doesn't matter whether it sounds good or not. These headphones are mostly closed-type because they require a quiet environment for listening. Sports headphones: Mainly worn during exercise. The main feature of this type of headphones is that they are lightweight, comfortable to hang and not easy to fall off. Noise-canceling headphones: This type of headphones is mainly used in noisy places. The basic principle is to record a period of ambient noise and process it in reverse phase. After it is sent to the driver, it cancels out the ambient noise. Noise-cancelling headphones usually come with a small microphone to pick up ambient noise. Voice headset: It is what everyone calls a headset, which is a headset or earplug with a microphone. Its main function is to realize voice communication, and so-called gaming headsets fall into this category. Wired earphones are classified according to the transmission method: Its characteristic is that it has metal wires directly connected to the audio source device. Wireless earphones: Wireless earphones are not bound by wires, but they have an additional wireless receiver and self-contained power supply, so they have great limitations. Before wireless technology was fully digitalized, wireless earphones were also susceptible to interference.

2. Distinguish by the way of wearing, mainly including: earplug type, in-ear type, head-mounted type, and ear-hanging type.

Earplugs are very common and have good sound isolation. Some people say that in-ear headphones hurt the ears. In fact, this is not the case. In-ear headphones enter the ear canal relatively deeply, so the sound does not need to be too loud, so there is no harm to the ears. People say it's so serious.

3. Classification of operating principles of different headphones: the common ones are dynamic coil, moving iron, and electrostatic.

Dynamic headphones are relatively efficient and can mostly be used to drive the headphone output of speakers. They are widely used, reliable and durable.

The advantages of moving iron earphones are long service life and high efficiency. The disadvantage is large distortion and narrow frequency response. The price is higher.

Electrostatic headphones are expensive and difficult to drive, and the sound pressure level they can reach is not as high as that of dynamic headphones. However, they have fast response speed, can reproduce various tiny details, and have extremely low distortion. .
