Differences between open and closed earphones

The shell of open earphones is open. Open earphones are light in weight, natural in sound, and free from pressure. Because it is open, sound will leak out and external noise will enter.

Semi open earphones mean that the earphones are selectively opened, that is, they are only open to certain frequencies and closed to other frequencies, or they are open in a certain direction and closed in other directions.

The enclosure of closed earphones is closed to prevent external sound from entering and reduce sound leakage. It is widely used in professional monitoring. Generally speaking, the sound is excellent, the details are rich, and the low-frequency response is very good. For most people, closed earphones have a closed texture.
