What Are Bone Conduction Bluetooth Headphones and How Do They Work?

Feb 21,2023 | David

Did you know that a new type of headphones is popular among young people now? They are bone conduction headphones. They're pretty cool, and a different type of headphone than all the ones that came before it. If you haven't read it, follow my article to find out.

What are bone conduction Bluetooth headphones?

Bone conduction headphones are headphones in which the sound generating unit is attached to temples. Their vocal units convert sound into mechanical vibrations, which cause bone vibrations, and transmit the sound to the auditory nerve.

They are vastly different from common headphones. Common headphones are air conduction, while the sound unit of them is a horn. When you play music, their horns convert the sound into sound waves, which travel through the air in your ear to your eardrum, causing the eardrum to vibrate and then send the sound to the auditory nerve, where it is finally heard by your ear. Bone conduction Bluetooth headphones convert sound into mechanical vibration when making sound, and directly transmit the vibration to the auditory nerve of the inner ear through the bone without passing through the air and tympanic membrane.

 

 

Because of this difference, the way bone conduction Bluetooth headphones are worn is also different. They don't need to be plugged into the ear, but hang on the pinna so that the sound unit is pressed against the temple. Of course, there is another type of clip-on bone conduction headphones, which are clipped to the ear when worn, and then the sound unit will stick to your auricle. But the vocalization and delivery of the sound is the same for both.

 

How do bone conduction Bluetooth headphones work?

When we speak, we ourselves actually hear the sound through the air (air conduction) and through the bones (bone conduction) at the same time. We may have become so used to it that we think that hearing our own voice is just transmit through the air. As an example,when you close your mouth while brushing your teeth, this ensures that there is no air-conducted sound, but you can still hear the brushing sound, and it is clearly heard, it is the sound through the bone.

Bone conduction technology is actually the technology of transmitting sound through bones. During the transmission process, the sound source causes the bone to resonate, thereby transmitting the vibration to the cochlea, which is the principle of bone conduction technology.

 

 

Bone conduction Bluetooth headphones are headphones manufactured based on bone conduction technology. When they work, people only need to stick the sound unit on the temple, and the sound unit will convert the sound signal into mechanical vibration, drive the skull to vibrate, and the skull will transmit the vibration to the cochlea. After the cochlea perceives the sound, it will be transmitted to the auditory nerve and brain. Finally, the sound is formed. This is how bone conduction headphones work.

Therefore, bone conduction headphones can hear the sound without being plugged into the ear. They can well protect the eardrum and maintain the hygiene of the ear canal, which is very helpful for ear health.In addition to be health and hygiene,the have a lot of advantages.

 

What are the advantages of bone conduction Bluetooth headphones?

First of all, because they use the principle of bone conduction to transmit sound instead of air conduction, most bone conduction headphones do not affect the acquisition of ambient sound by both ears when used. Therefore, it is very safe when you use it outdoors, and you will not ignore the possible dangers because you are immersed in the music when wearing it.

 

 

Secondly, because most of the them are close to the hard bone position (beside the ear), instead of directly blocking the ear canal like in-ear headphones, or clamping the soft tissue of the ear like clip-on headphones.After wearing bone conduction headphones for a long time,ear damage cause of Headphones is much less than in-ear headphones or clip-on headphones. For example, if you wear them for four hours, clip-on headphones may cause your ears to hurt unbearably, but even if you wear bone conduction headphones for a long time, you will basically feel nothing. Therefore, they are very comfortable to wear.

On top of that, common headphones can clog the ear canal, leading to the growth of a lot of bacteria that can lead to ear infections. Bone conduction Bluetooth headphones do not have these effects because they do not need to be worn in the ear, and they will not rub against the external auditory canal when worn. So they are more suitable for people with oily ears, otitis media, small ears, and some people with sensitive ears because they do not need to be inserted into the ears. They are also more suitable for people who need to wear headphones for a long time. Therefore, bone conduction headphones are very healthy.

Bone conduction headphones have relatively little hearing damage, because hearing damage generally occurs in the eardrum and inner ear, while bone conduction headphones directly bypass the eardrum to avoid eardrum damage. Moreover, the vibration waves of them are relatively moderate, and the impact on auditory hair cells will be less, so the damage to hearing caused by them is minimal. For these reasons, bone conduction headphones have become very popular these years.

 

Bone conduction Bluetooth headphones have obvious advantages, which is why they have become star products in the past two years.So, how to choose the right headphone? I think the sound quality, sound leafage reduction ,comfort and product configuration should all be considered. Now I will recommend some excellent products below.

 

1 Wissonly Hi Runner bone conduction Bluetooth headphones

 

Reason for recommendation:

Wissonly is one of the few bone conduction headphone brands that have mastered bone conduction vibrator technology, and one of the few brands in the industry that have sustained experience in using bone conduction technology to protect hearing. Wissonly Hi Runner advocate a healthy way to listen. They perfectly combine the principles of healthy hearing and bone conduction sound transmission, to create a non-in-ear and non-ear-damaging bone conduction headphone which can effectively protect hearing.

Due to the particularity of the technical principle, sound quality of bone conduction headphones is more difficult to be improved . To this end, Wissonly Hi Runner subverts the traditional sound quality scheme, makes a breakthrough to use the large-size bone conduction vibrator. Through structural optimization, the effective vibration area of the vibrator is increased by 35%, thereby improving the vibrator sound efficiency, making the sound more powerful.It also optimizing the direction of sound transmission, reducing sound loss during sound transmission, and making the sound more concentrated.

The skin-friendly silicone material of the Wissonly Hi Runners body is a product that can be in contact with the skin for a long time. It is naturally a better choice and feels good to the touch. Because the entire headphone is made of skin-friendly material, it is very comfortable to wear. Even if you wear glasses, you can still hang it firmly on your ears. The headphone frame uses memory titanium, which has the advantage of being stretchable and lightweight.

 

2. Philips A6606 bone conduction Bluetooth headphones

 

Reason for recommendation:

In terms of appearance, A6606 adopt a simple and solid color design. Except for the logo at the end of the ear hook, there is no unnecessary decoration. The overall sense is very strong, and they visually give people a simple sense of technology. They feel quite good to wear, neither compressing the head and cervical vertebrae nor messing up the hair. A6606 do not need to be worn into the ears. They do not hurt the eardrum during long-term wearing ,and they will not cause you sweat during exercise, and are comfortable and breathable. In addition, their IP67 dustproof and waterproof rating, 9-hour battery life, Bluetooth 5.2 and other features make the bone conduction headphones a good choice.

 

3.AfterShokz OPENRUN PRO bone conduction Bluetooth headphones

 

Reason for recommendation:

Openrun Pro bone conduction headphones with ergonomic ear-sticking design, which is worn by hanging ears, it have a light body, so they are comfortable and stable to wear. It supports IP67 waterproof, adopts magnetic contact to avoid water seepage for charging, and in order to be waterproof, it is coated with antioxidant nano-coating to isolate water vapor on the chip. Normal sweat and ordinary washing are no problem, even in the rain for a short time is ok, but it can't be used for swimming.

 

4.earsopen SS900 bone conduction Bluetooth headphones

 

Reason for recommendation:

It adopts the 5.2 Bluetooth protocol, which can start automatic connection when the charging compartment cover is opened. It is low latency during use, and the anti-interference ability is also strengthened. In terms of sound quality, BoCo's miniature bone conduction vibrator is adopted, which has good performance at low frequencies, but which has harsh noise and serious sound leakage at high frequencies. The 8G single-earphone body is basically comfortable during the whole wearing process.

 

5. vidonn F3 bone conduction Bluetooth headphones

 

Reason for recommendation:

The weight of this bone conduction headphone is only 29g, and there is comfortable when it is used, whether it is hanging on the neck or hanging on the ear for a long time. The charging port of F3 headphones is a universal standard MICRO-USB interface. The charging port is waterproof with a soft rubber plug, which is not connected to the body, so there is a risk of loss. The disadvantage is that the sound quality is average, and the sound leakage is serious.

 

Among the several bone conduction headphones recommended above, wissonly and aftershokz are my favorite brands. Compared with them, Wissonly is more cost-effective and worth buying.
