What are the advantages and disadvantages of bone conduction headphones?

(1) Health

Bone conduction is the principle of bone vibration and sound transmission, which transmits sound directly through the skull to the ear nerve inside the ear. Because the eardrum is not required, hearing is not affected.

(2) Security

Sounds around bone conduction headphones can still be heard and general conversations can be carried out, which also avoids the risk of accidents caused by not being able to hear outside sounds.

(3) Hygiene

Because bone conduction headphones do not need to be placed in the human ear, it is very helpful to maintain the hygiene inside the ear; At the same time, the bone conduction headphones have a smooth surface and are easy to clean. Traditional in-ear headphones are prone to bacterial deposits.

(4) Comfort

The bone conduction headphones are fixed on the head, and they will not fall off during exercise, which will not affect the good mood of running and listening to songs.

Disadvantages of bone conduction headphones:

(1) Sound quality

Because it is transmitted through the skin, bone and skull to the ear ossicles, the separation and reduction degree of ** is worse than that of in-ear headphones. However, everyone's feelings and preferences for ** are different, and you can only know how well the headphones sound after actually listening to them. However, in the case of sports earphones, in addition to the sound quality, it is more important whether they can fit snugly with the ears, not shift or fall off due to shaking, and not bring additional weight burden to the head and ears.

(2) Sound leakage

Although bone conduction headphones can clearly transmit sound through the skull to the inner ear, for the sake of wearing comfort, the bone conduction headphones do not adhere to the skull, so some of the energy will cause air vibration and cause sound leakage.

Classification of bone conduction headphones.

Bone conduction headphones are divided into bone conduction speaker technology headphones and bone conduction microphone technology headphones.

a) Bone conduction speaker technology headphones:

Using bone conduction technology, sound waves are transmitted directly through the bone to the auditory nerve by pressing close to the bone. Therefore, both ears can be opened without harming the eardrum. In the military and civilian fields, it is generally used to directly conduct sound on the cheekbones of the face.

b) Bone conduction microphone technology headphones:

Bone conduction technology is used to collect sound, and sound waves are transmitted through the bones to the microphone. In the civil field, bone conduction technology is generally used to reduce noise.

Due to the needs of military scenes, sometimes it is not possible to speak loudly, and the loss rate of sound conduction in the bones is much lower than that of air conduction, while bone conduction microphone technology headphones mainly use throat bone conduction. Due to the short distance, the loss is low. The soldier only needs to make a small sound to deliver exactly what he wants to say.

01 Advantages of bone conduction headphones: reduce the impact on ear hearing; Listening to songs with headphones can still hear the surrounding sounds, which improves the safety of outdoor sports; The headphones do not fit into the ear, which is very helpful for maintaining the internal hygiene of the ear; It is not easy to fall off, etc. Bone conduction headphones disadvantages:

**The degree of reduction is worse than that of the traditional in-ear type; There are sound leaks, noise, etc.

Advantages of bone conduction headphones:

1. Health: Bone conduction is the use of bone vibration sound transmission principle, does not enter the ear, does not need to be transmitted directly through the eardrum, the new concept of bone conduction directly through the skull to conduct sound to the internal nerves of the ear, the impact on ear hearing to the minimum.

2. Safety: Bone conduction headphones that do not fit into the ears, whether running, cycling, walking or commuting, etc., can still hear the surrounding sounds when listening to songs while wearing headphones, and can communicate with others normally, avoiding the danger of accidents caused by not hearing the sound of the outside world, and greatly improving the safety of outdoor sports.

3. Hygiene: Bone conduction headphones do not enter the ear, which is very helpful for maintaining the internal hygiene of the ear. It will not be clogged with a large number of bacteria due to sweating for a long time during exercise, which is more hygienic.

4. Comfort: Bone conduction headphones are generally fixed to the head in the over-ear style, and are generally anti-shake design, which is not easy to fall off.

Bone conduction headphones disadvantages:

1. Sound quality: Because it is transmitted through the skin and skull to the ear ossicles, the reduction degree is definitely worse than the traditional in-ear type, but from the perspective of sports headphones, in addition to the sound quality, the earphone fit is not easy to fall off, light and convenient is more important, and the poor sound quality is only compared with the same price in-ear headphones, it is not bad to enter the ear, and most of the bone conduction headphones have improved the sound quality to varying degrees.

2. Sound leakage: Bone conduction headphones can clearly transmit sound through the skull into the inner ear, but for the sake of wearing comfort, it will not be completely close to the skull, so some of them will cause air vibration and then produce sound leakage. This is unavoidable for all bone conduction headphones on the market, but with the rise of the technical level, the current bone conduction headphones on the market have reduced the sound leakage to varying degrees.

3. Noise: When shopping or taking public transportation, the environment is noisy, and the external sound will overwhelm the sound of the headphones, and the listening effect is not ideal, but at present, there are bone conduction headphones that have adopted effective noise reduction technology, and the normal use of listening is basically not affected.
