Open Headphones Are A Common Type of Headphones with Features That Include

1. **NATURAL SOUND FIELD**: The open headphone design allows ambient sound to pass through the headphone housing, making the audio sound more natural and open. This design allows the listener to feel as if the music is coming from the surrounding environment rather than being limited to the inside of the headset.

2. **Comfort**: Open-back headphones typically have a lightweight, breathable design that is more comfortable for extended wear. Because of their ventilation, open headphones are less likely to make your head feel stuffy when you wear them.

3. **AUDIO ACCURACY**: Open headphones are designed so that the audio does not bounce or reverberate inside the housing, thus providing a more accurate audio performance. This makes open headphones widely used in audio production, professional recording and other fields.

4. **Socialization**: Open headphones allow the sound of the surrounding environment to pass through, which is very convenient for situations where you need to communicate with others, such as in the office, at home, or during outdoor activities.

5. **AUDIO PERMEABILITY**: Since ambient sound can pass through the headphone shell, open headphones allow users to enjoy music while remaining aware of their surroundings, which is especially useful for activities such as walking and running, and improves user safety.

6. **NOT SOUND INSULATED**: The design of open headphones means that they are not effectively sound insulated, which means that in noisy environments, outside sounds can interfere with the user's music experience. Therefore, closed headphones may be more appropriate in situations where they need to be used in a noisy environment.

Overall, open headphones are favored for their natural soundstage, comfort and sociability, but they are relatively limited in their ability to isolate sound, which is a factor users need to consider when choosing headphones.
