Are Bone Conduction Headphones Harmful to Health?How About Their Working Principle?

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 headphones 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 bone conduction headphones which have become popular in recent years.

Bone conduction headphone is a kind of healthy earphone, which will not harm health.

Are bone conduction headphones harmful to health

Some people may worry that bone conduction headphones 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 bone conduction headphones 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 bone conduction headphones is relatively gentle and stable, and will not cause damage to the cochlea.

2. The effect of bone conduction headphones 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 bone conduction headphones 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 bone conduction headphones causing bone damage.

4. The effect of bone conduction headphones 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 bone conduction headphones are made of skin-friendly materials, and are also more friendly to skin.

Therefore, bone conduction headphones 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.

The safety and health of bone conduction headphones have been recognized by many consumers. These advantages are determined by their working principles.

How do bone conduction headphones work?

When it comes to the working principle of bone conduction headphones, you must first understand the "essence of sound". Simply put, the sounds we hear every day are vibrations in the air. For example, have you ever seen a scene of “loud high-pitched sound shatters a glass window”on TV? This phenomenon is caused by the treble that transmits strong air vibrations to the glass window, causing the glass window to resonate.

We hear sound as vibrations in the air. Sound travels through the ear canal to the eardrum, then through a spiral organ called the cochlea to the brain, where it is finally perceived by us. While common headphones that fit into the ear canal use this "standard" path to transmit air vibrations to the brain, bone conduction headphones work quite differently.

The sound transmission path of common headphones: sound source vibration → external auditory canal → eardrum → cochlea → brain

The sound transmission path of bone conduction headphones: sound source vibration → skull → cochlea → brain

So, with bone conduction headphones, you can enjoy music without ear canals or eardrums. Bone conduction headphones do not need to be plugged into the ear canal when worn, which will cause less damage to the eardrum and better hygiene for the ear canal, so they are the healthiest headphones.

Because bone conduction headphones are so safe and healthy, I strongly recommend that people who love sports have one.Here are some excellent headphones recommended for you.

1. Wissonly Hi Runner bone conduction headphones

Reason for recommendation:

This is the fastest growing brand of bone conduction headphones in the last six months. The team are all engineers with 10 years of accumulation in the field of bone conduction technology. They started to develop bone conduction headphones that don't hurt ears as early as 2012. To solve the problem of sound leakage of bone conduction headphones, wissonly has made comprehensive improvement in the aspects of vibrator, body design and software optimization. The final result has been applied to Wissonly Hi Runner, and the final sound leakage can be reduced by 90% after laboratory test. I actually used the test myself. At a distance of 2cm, the volume reached 70%, but I still didn't hear the sound of the headphones, which protected my privacy.

Wissonly Hi Runner’s body is made of titanium, which can self-adjust the fitting position to ensure a good wearing experience for headphones, so that more people can wear it. As the core component of the product, the headphones plays a key role in the product experience. Hi Runner model is equipped with Bluetooth 5.0 chip, which makes Bluetooth connection faster and more stable. It also has 32GB of built-in storage so you can use it as an MP3 player.

Other parameters of Wissonly Hi Runner are also excellent. For example, the waterproof level reaches IPX8, and you can wear it to swim or even dive. The battery life reaches 8-10 hours, which is very important to me, because I go out for sports on weekends, and I go out for a whole day.

2.Philips A8606 bone conduction headphones

Reason for recommendation:

The most peculiar point of Philips is that it is equipped with LED night running lights at the rear end of the fuselage, and the A8606 is also the same. The back of both sides of the headphones has rain-shaped lights flashing, wearing it at night can make people around you alert to your location. And turning on them during exercise can improve the safety factor, and night travel can also achieve the effect of not being collided. The Bluetooth version of 5.0 can maintain the smoothness of listening to songs at a short distance, and the 13.3mm vibrator makes it have a good performance in sound quality.

3.AfterShokz OPENRUN PRO bone conduction headphones

Reason for recommendation:

AfterShokz Openrun Pro's headphones are very light, weighs only 26g. It's very light and comfortable to run on your ears. The whole machine is made of titanium alloy, and the headphones on both sides are wrapped with skin-friendly silica gel, which make it has a IP67 waterproof grade.

The structure adopts the back-hanging design and can't be worn in the ear, which is very friendly to users who often wears it. The whole machine is also equipped with Bluetooth 5.0 three-core chip, which can realize fast connection, stable sound quality connection within 10 meters, and intelligent identification by algorithm, which can effectively filter the ambient sound and make the voice clearer.

4 Earsopen BT5 bone conduction headphones

Reason for recommendation:

earsopen BT5 bone conduction headphones are originated in Japan and can play music continuously for up to 6 hours. They adopt IPX7 waterproof design, are not afraid of sweat in sports, and are very suitable for use in sports scenes. Their unique audio equalization technology and high-performance vibration unit support sound of different frequencies. BT5 have an echo reduction function to minimize echo.

5.Nank Runner CC3 bone conduction headphones

Reason for recommendation:

The titanium alloy body of the Runner cc2 bone conduction headphones is more flexible and durable, and there is no need to worry that the paint of wearing the headphones for a long time.
