In daily life, the sound of teeth colliding can be clearly heard by us, but people around us cannot hear it. This is probably the nearest case of bone conduction technology around us. When you collide your teeth, you may hardly imagine that this sound transmission method will be applied by talented engineers to create the latest popular product-bone conduction earphones.

what are headphones with bone conduction?

Bone conduction headphone is a type of headphone using bone conduction technology. Its biggest feature is that it uses bone conduction to transmit sound, uses human bones as the medium for transmitting sound, and directly transmits sound to the auditory nerve to form hearing.

This distinctive technical feature has also revolutionized the way it is worn. The wearing method of bone conduction earphones has changed from traditional in-ear wearing to hanging ear wearing. When wearing it, you only need to hang the earphone on the auricle and put the vibration unit close to the temple, and the whole ear is completely open. The change in the way of sound transmission and wearing has made headphones with bone conduction another type of earphone, which is a huge upgrade compared to traditional earphones. Many ear doctors also highly recommend them, because they are better and healthier for ears.

Are headphones with bone conduction good for your ears?

Headphones with bone conduction are good for the ears, they cause less damage to the ears and are the healthiest kind of headphones.

1. Does not harm the ear canal

headphones with bone conduction do not need to be plugged into the ear canal when wearing them, so the damage to the ears caused by wearing headphones will not happen.

2. No damage to the eardrum

headphones with bone conduction do not need to use the ear canal and eardrum to transmit sound, so the eardrum will not be damaged.

3. Does not harm the cochlea

The vibration waves of headphones with bone conduction are relatively gentle and stable, and will not damage the cochlea.

4. Does not harm the auditory nerve

The electromagnetic waves of headphones with bone conduction are weak, which is close to the intensity of electromagnetic waves in nature, so they will not damage the auditory nerve.

Special attention should be paid to the fact that if any headphone is used at high volume for a long time, it will cause damage to the ears, and the same goes for headphones with bone conduction. Therefore, pay attention to volume control when using headphones with bone conduction, and it is recommended that the volume not exceed 60%. At the same time, every 2–3 hours of use, you should rest for 10–15 minutes.

In addition to the advantage of being good for the ears, headphones with bone conduction have many advantages, such as

1.They are safer

They do not need to be inserted into the ear canal when worn. While listening to music, you can still pay attention to the surrounding sound. When exercising outdoors, wearing with headphones with bone conduction, you can also hear the sound behind you, so as to avoid some dangerous situations.

2. They are more hygienic:

headphones with bone conduction do not need to be worn in the ear, even if they are worn for a long time, they can keep the ear canal clean and hygienic, avoiding the growth of bacteria caused by blocking the ear canal, which can cause otitis media, otitis media and other diseases;

3. They are more comfortable:

headphones with bone conduction are very light, and there is no sense of weight when worn, and the surface of many headphones with bone conduction is made of skin-friendly soft materials, which is very comfortable to wear.

Headphones with bone conduction that are good for the ears are also safer, more hygienic, and more comfortable headphones. These advantages are determined by their working principles.

What is the working principle of headphones with bone conduction?

Before understanding the working principles of headphones with bone conduction, we need to review our middle school physics to understand the three mediums for sound transmit: air, solids, and liquids. Air conduction is what we know most about, such as ordinary conversation is the case that sound transmit through air. When your place ear to the railway, and when a train comes in the distance, you can hear the sound, which is the case of sound transmission by solid. When we dive, we can hear the sound of the engine of a ship in the distance, which is the case of sound transmission by liquid.

Headphones with bone conduction are a device that transmits sound through solid (bone) conduction. It transmits sound by vibrating your skull. This is unlike the air conduction of traditional wired and wireless headphones. headphones with bone conduction do not transmit sound through the eardrum, so even if the volume is slightly louder, it will not easily damage the eardrum.

We can compare the sound transmission paths of bone conduction and air conduction

Bone conduction pathways: sound waves, skull, bone labyrinth, inner ear lymph, spiral organ, auditory nerve, auditory center of the cerebral cortex

Air conduction pathways: sound waves, auricle, external auditory canal, periosteum, ossicles, vestibular window, internal and external lymph, spiral organ, auditory nerve, cerebral cortex auditory center

We can see that bone conduction has a shorter sound transmission path than air conduction, and that it takes a shortcut. And this shortcut helps headphones with bone conduction not to be stuffed into the ear or wrapped around the ear. So the headphones will not cover the ear canals and have no damage to the eardrums, and the damage to the auditory nerve is relatively low.

It can be said that headphones with bone conduction are good for using, and the following i will recommends several good headphones to everyone.

1. wissonly Hi Runner headphones with bone conduction

Reason for recommendation:

Wissonly’s core team is a team engaged in the research and development of bone conduction products earlier. They have accumulated 10 years’ technology in this field. They have adopted the best acoustic laboratory in the Eastern Hemisphere for sound adjustment.
