What Are True wireless Bluetooth Bone Conduction Headset Phones and Are They Harmful to Health?

 Wireless Bluetooth bone conduction headset phones are a new type of headphones, because they have many advantages that traditional headphones cannot match, so they are gaining the favor of a large number of users. But at the same time, some merchants sell fake wireless Bluetooth bone conduction headset phones in pursuit of short-term profits. So what are real wireless Bluetooth bone conduction headset phones? How should we tell the difference? let me tell you in the article.

What Are True wireless Bluetooth bone conduction headset phones?

A wireless Bluetooth bone conduction headset phone is a type of headphone that uses human bones as a sound transmission medium. They are generally ear-mounted, and the vibration unit is attached to the temple, and the vibration is transmitted to the inner ear through the skull, so that people can hear the sound. The fake wireless Bluetooth bone conduction headset phones are actually a kind of air conduction headphones that look like wireless Bluetooth bone conduction headset phones. They rely on two external speakers attached to the temples to produce sound, and then transmit the sound to the eardrum through the air, causing the eardrum to vibrate, and then to the eardrum, and the inner ear.

For real wireless Bluetooth bone conduction headset phones, their body has no openings and is generally an integrated body with a relatively high waterproof level. Since they rely on bone conduction sound, you can try to plug your ears after wearing them, and you will find that the sound of the real wireless Bluetooth bone conduction headset phones will be louder, while the sound of the fake ones will be significantly smaller. This is the easiest and most convenient way to distinguish between real and fake wireless Bluetooth bone conduction headset phones.

What is the working principle of wireless Bluetooth bone conduction headset phones?

Before understanding the principles of wireless Bluetooth bone conduction headset phones, 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.

Wireless Bluetooth bone conduction headset phones 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. wireless Bluetooth bone conduction headset phones 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 wireless Bluetooth bone conduction headset phones 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.

Are wireless Bluetooth bone conduction headset phones harmful to health

Some people may worry that wireless Bluetooth bone conduction headset phones are harmful to health. This concern is unnecessary, and there is no evidence that this kind of headphones are bad for health. We can analyze this problem from several perspectives on the effects of them on the ears, nervous system, bones, and skin.

1. The effect of wireless Bluetooth bone conduction headset phones on the ear

They do not need to be tucked into the ear canal when worn, which avoids damage to the ear canal caused by headphone plugging in and out. They also do not need to transmit sound through the ear canal and eardrum, which makes them have no harm to the eardrum. The oscillation of wireless Bluetooth bone conduction headset phones is relatively gentle and stable, and will not cause damage to the cochlea.

2. The effect of wireless Bluetooth bone conduction headset phones on the nervous system

Any electronic product has electromagnetic waves, and strong electromagnetic waves can damage the auditory nerve and brain nerves. The electromagnetic waves of them are very weak, and the intensity is close to that of the electromagnetic waves present in nature, so they do not harm the auditory nerve and brain nerve.

3. The effect of wireless Bluetooth bone conduction headset phones on bones

The sound unit of them vibrates and drives the bone vibrate to achieve sound transmission. Excessive vibration may theoretically lead to bone damage, but this theoretical vibration rarely happens. There are currently no records of wireless Bluetooth bone conduction headset phones causing bone damage.

4. The effect of wireless Bluetooth bone conduction headset phones on the skin

They are worn against the temple, do not over-squeeze the skin, and therefore does not cause damage to the skin. And many wireless Bluetooth bone conduction headset phones are made of skin-friendly materials, and are also more friendly to skin.

Therefore, wireless Bluetooth bone conduction headset phones are not harmful to health, but one kind of healthiest headphones. They are safer and more hygienic when used, and are a kind of excellent headphones.

Now that we are sure that bone conduction headset phones are safe.So how to choose the most appropriate headphones? My suggestion is to choose brands with accumulated technology in this field. These brands are excellent in terms of sound quality, sound leakage reduction technology, safety, etc. Next, I will recommend some excellent headphones.
