What are Bluetooth Bone Conduction Earphones and Best Bone Conduction Earphones in 2023

Have you ever heard music with headphones on while walking on the road, when the car behind you honks to remind you, everyone around you heard it, but you didn’t know it; or when you listened to music while wearing earphones in the office at work, even if your boss yells next to you, it can't wake up your ears that were kidnapped by music. These awkward moments happen a lot in life, and they're always unpleasant. However, there is a kind of headphone that can perfectly help you avoid these embarrassments, that is bluetooth bone conduction earphones that have become popular in recent years.

What are bluetooth bone conduction earphones?

Bluetooth bone conduction earphones are headphones that are worn differently from traditional earphones. They don't have earbuds in your ears like common earphones do, and they don’t need the sound to travel through the air in the ear canal to the eardrum like common type do. They are generally hung on the auricle, so that the sound unit is against the temple, and the mechanical vibration signal of the sound unit is transmitted to the auditory nerve of the inner ear through the skull, and finally people hear the sound.

Bone conduction technology is widely used in the military, emergency rescue, hearing assistance and other fields. Bluetooth bone conduction earphones are a new application of this technology in the field of consumer electronics. They are mainly positioned in the field of sports earphones. The existing products include running earphones, swimming earphones, cycling earphones and so on. They are becoming more and more popular due to the advantages that traditional earphones do not have, such as safety, health, hygiene, etc.Their advantages are determined by their working principles

How does bluetooth bone conduction earphones work?

The propagation medium of sound includes solid, liquid, and air. In general, there are two ways for sound waves to enter the inner ear of the human body: air conduction and bone conduction. It then travels to the inner ear via the auditory ossicles. Bone conduction is the vibration of sound waves through the bones of the head such as the skull and jaw, which transmits the sound to the inner ear. It is another very important hearing method besides air transmission. People use this method to manufacture many bone conduction hearing devices.

Common earphones mainly transmit sound through the air, while bluetooth bone conduction earphones use the temporal bone of the head to transmit sound. It transmits sound directly to the auditory nerve in the form of sound waves, instead of passing through the air to the eardrum and then to our auditory nerve.

Currently, bone conduction hearing devices mainly include electromagnetic bone conduction earphones and piezoelectric bone conduction earphones. Electromagnetic bone conduction earphones have better working performance, but they have electromagnetic radiation, which is easy to cause harm to the user's body. Piezoelectric bone conduction earphones use piezoelectric vibrators as sounding components. When people wear it the human body is less affected by electromagnetic radiation which also has the advantages of small size and low power consumption.

Advantages of bluetooth bone conduction earphones

The way bluetooth bone conduction earphones are worn without earbuds brings tangible benefits:

Safer: It does not block your ears when wearing it, allowing you to maintain awareness of the surrounding environment, making outdoor sports safer;

Healthier: it uses bones to transmit sound, and the sound is directly transmitted to the auditory nerve, avoiding damage to the eardrum, and can protect hearing well;

More hygienic: Bluetooth bone conduction earphones do not need to be worn in the ear, even if worn for a long time, they can keep the ear canal fresh and avoid otitis media, otitis media and other diseases caused by blocked ear canal;

More comfortable: They are very light, and there is no sense of weight when worn. The surface of many bluetooth bone conduction earphones is made of skin-friendly soft material, which is very comfortable to wear;

Unique appearance: wearing bone conduction earphones with unique design can help you attract more people's attention;

When keeping in touch with the outside world, you can communicate with friends or colleagues while listening to music, and you will not neglect them because of listening to music.

There are two sides to the coin, bone conduction earphones have many advantages, but it also has some disadvantages. Two of the most common shortcomings are sound quality and sound leakage.

In terms of sound quality, the sound quality of bluetooth bone conduction earphones is slightly worse than that of traditional noise-canceling headphones. Due to the working principle of sound generation and sound transmission of them, when the sound unit vibrates the skull, it also vibrates the air, resulting in sound leakage. These two shortcomings, all bluetooth bone conduction earphones have, those ones that claim to be completely free from these two problems do not exist.

Of course, the sound quality of bluetooth bone conduction earphones is not so bad that it is intolerable. The sound quality of some good headphones is very close to that of common earphones. You can hardly feel these leaks under normal social distance and normal volume. There are also some brands by structural optimization, and the problem of sound leakage has been greatly improved.

So, to be honest, bluetooth bone conduction earphones are becoming more and more worth buying.Here are some excellent earphone products below.
