As a music lover, out of the pursuit of sound quality and wearing comfort, I have bought many types of earphones, including wired earphones and wireless Bluetooth earphones. There are two different audio transmission methods. The characteristics are also different. As for the latter wireless Bluetooth headset, in today's main demand that people are pursuing convenience, ease of use, and comfort, there is a branch that breaks through the existence of conventional in-ear headphones-open headphones.
Open earphones are a type of earphones with unique design features, which are obviously different from closed earphones in design. The characteristic of open earphones is that the earphones are worn in such a way that they do not enter the ear. They are usually worn in ear-hook, suspension, etc., so that air and sound can circulate freely inside and outside the earphones.
In contrast, closed earphones use a more airtight design to isolate the ear from the external environment. In addition, the sound transmission methods of open earphones are also divided into bone conduction technology and air conduction technology. There are great differences in working principles, but what they have in common is that they can bring users a wider range of audio experience. Also due to the characteristics of the wearing method, it has a more comfortable open wearing experience.

2. What is the concept of open earphones?
The concept put forward by the open-back headphones is that the design concept aims to provide users with a more natural and open audio experience.
In the built-in design of the fuselage and the speaker, the main purpose of the open earphone is to reduce the audio blocking in the ear as much as possible, and to allow the natural sound of the surrounding environment to mix with the audio in the earphone. This creates a more realistic sound field.
Therefore, open earphones will be more suitable for users who pay more attention to natural sound quality and comfortable wearing. At the same time, open earphones are also very suitable for user groups who need to constantly perceive changes in the surrounding environment. Therefore, open-back headphones can be applied to many scenes and human groups.
3. What is the difference between open earphones and closed earphones?
When we see the word "open", we can't help but think of its corresponding "closed"; nowadays, earphones on the market can be divided into closed, semi-open and open according to the degree of openness. types. In fact, the biggest difference between traditional closed earphones and open earphones that break through the tradition is that there is a big difference in the effect of sound insulation.
Closed earphones, as the name suggests, explain that this type of earphone needs to be placed in the ear canal, and the sound insulation effect is the best. However, long-term use can also cause some health problems in the ears, such as otitis media, etc. Put it on top.
The design feature of open earphones is that during use, the back or shell of the earphone has a certain open hole or grid structure, allowing air and sound to circulate freely inside and outside the earphone. The sound insulation effect is slightly lower than that of closed headphones. However, thanks to the open ear design, it brings a healthier and more comfortable wearing experience.
4. What are the sound transmission technologies of open earphones? Is there any difference between them?
The sound transmission technology of open earphones can be divided into bone sound transmission through the vibration of ear bones and air transmission technology through the air for audio transmission.
Bone conduction, bone conduction technology bypasses the traditional auditory pathway of the ear by transmitting sound vibrations directly to the skull. This sound transmission method keeps the ear canal open, and the user can hear the sound of the external environment while enjoying audio playback.
Air-transmission technology, air-conduction technology is to transmit the sound vibration in the air to the ear to realize the auditory perception. This way of sound transmission creates a more natural and open sound field, while maintaining a certain sense of environment.
Both bone sound transmission and air sound transmission have their own advantages and applicable scenarios. Bone sound transmission is more suitable for situations where awareness of the external environment needs to be maintained, such as outdoor sports or occasions where simultaneous voice calls are required. The air transmission sound is more suitable for focusing on sound quality performance and sound field sense, suitable for daily listening to music, entertainment or office environments.
5. What are the advantages of open earphones?
1. Audio spillover: Open-back headphones allow part of the audio to overflow the ear canal, allowing people around to hear some of the audio as well. This design creates a more natural and open sound field, allowing users to experience a more realistic music environment.
2. Natural sound range, maintaining perception: By reducing the closure of the ear canal, open-back headphones allow ambient sound to enter the ear canal more naturally. This allows users to maintain awareness of their surroundings while wearing the headset without being completely cut off from the outside world.
3. Permeability and comfort: Due to the escape of audio and the entry of ambient sound, open earphones create a wider sound field, giving people a sense of openness. This sense of sound field makes the music more real and three-dimensional, and enhances the listening enjoyment.
6. What are the more mature brands of open earphones? How to choose open-back headphones?
The rise of open earphones is inseparable from the new upsurge in the circle, and the efforts of various audio brands that are constantly in-depth research in the open field and strive to break through. At present, the technically mature brands in the open headphone market include Nanka, Sony, Philips, Shaoyin and other deadly audio brands.
7. What aspects should we pay attention to when purchasing open earphones?
We can make a comprehensive connection from the aspects of headphone brand, sound transmission method, audio protocol, appearance design and wearing comfort before making a purchase decision.
First of all, starting from the headphone brand, we can start with brands with relatively mature technology, such as South Carolina, Sony, Philips and other well-known brands, which are guaranteed in terms of word-of-mouth, quality and after-sales.
Secondly, understand whether the sound transmission technology of the earphone is the bone sound transmission technology or the air sound transmission technology, because these will affect the sound quality experience when we are about to use the earphone; there is also the size of the dynamic unit, because different Each size has its own suitable audio part.
Again, pay attention to the audio transmission protocol supported by the headset, which is also one of the most important key factors affecting the sound quality of the headset. The better the decoding of the audio transport, the higher the sound quality will be.
The next step is to look at the configuration performance of the earphone style, for example, is the Bluetooth chip version from Qualcomm or other manufacturers? The Bluetooth version is 5..0, 5.2 or 5.3 technology chip; if necessary, you can also pay special attention to the waterproof level of some earphones.
Finally, the appearance and wearing design of the earphones. As a fashion item, earphones not only pursue the performance of the earphones, but also the aesthetics of the appearance is a small point that can improve happiness.
