What Is The Difference Between Bluetooth Bluetooth bone conduction headphones and Air Conduction Headphones

Feb 28,2023 | David

In the last 2 years, Bluetooth bone conduction headphones are becoming more and more popular. Whether you go out for running, cycling, or going to the gym, you can see someone wearing them. As a star technology product, they are very different from common headphones. Undoubtedly they are not another headphones, but another kind of headphones.

What is the difference between Bluetooth bone conduction headphones and air conduction headphones

Their biggest difference is the way to transmit sound. Bluetooth bone conduction headphones use bones to transmit sound, while common headphones are air conduction headphones that use air to transmit sound. To understand this difference, I did a test. First put on Bluetooth bone conduction headphones, and then plugged my ears with my fingers, at this time I found that the sound became louder rather, which is amazing! But when I wear the air conduction headphones, when I do the same action, I find the sound becomes smaller.This is the secret of bone conduction transmitting sound!


The difference in sound transmission mode makes that you do not need to stuff the Bluetooth bone conduction headphones into the ear and only need to attach the vibrating unit to the temple to allow the ear to hear the sound. This feature also gives more design space for the headphones, and designers design them as hanging-ear type or clip-on-ear type so that they are more comfortable to wear. And because Bluetooth bone conduction headphones do not need to transmit sound through the air, their body do not need to leave holes for sound waves to enter and exit, which also allows them to have a better waterproof level.

The working principle of Bluetooth Bluetooth bone conduction headphones

Bluetooth bone conduction headphones are a kind of headphones that uses bone conduction technology, they are placed close to the bones, and sound waves are directly transmitted to the auditory nerve of brain through bones.

To understand the working principle of Bluetooth bone conduction headphones, we must mainly understand the sound transmission method and path. We can first look at the working principle of traditional headphones, and then make a comparison. Then it is clear.

Under normal circumstances, traditional headphones are essentially "air conduction headphones" that use the air in the external ear canal as the main sound transmission medium. In the air conduction process, the micro-horn of the headphones vibrates. Then sound waves are transmitted through the air in the external auditory canal to the eardrum, the ossicle, the labyrinth of inner ear and other parts. The vibration of the internal and external lymphatic fluid in the inner ear helps the spiral organ to complete the perception of sound, and then transmit to the auditory nerve. The auditory nerve produces nerve impulses and presents signals to the auditory center, and the cerebral cortex help us to "hear" the sound after comprehensive analysis.



The biggest unique feature of Bluetooth bone conduction headphones is that sound waves do not pass through the air in the external auditory canal and eardrum, but directly use the human bone as the sound transmission medium. When using, we need to put the sound source of the headphones against the skull behind the ear. And when the sound source vibrates, it will drive the skull to vibrate together, so that the sound wave is transmitted into the skull. And then the sound wave is directly transmitted to the ossicles through the skull bypassing the external auditory canal and the ossicles. And then the ossicles transmit sound waves into the bone labyrinth, so that the sound information is transmitted to the cochlea and auditory nerve etc..


More and more people are interested in Bluetooth Bluetooth bone conduction headphones, and more and more earphone manufacturers are joining this market. Then, how to choose the right Bluetooth bone conduction headphone is a problem. In the following, I recommend five earphones, all of which are of good quality and cost-effective

1. Wissonly Hi Runner Bluetooth bone conduction headphones


Recommended reason:

Wissonly bone conduction brand insists on technological innovation, its bone vibration technology is relatively leading. The team has 10 years of technical accumulation in the field of bone conduction. So they have mastered the core technology of the field, which is very important for the quality of the product.

Wissonly has exclusive sound leakage reduction technology and bone vibration technology, which are all applied to Wissonly Hi Runner Bluetooth bone conduction headphones. They can effectively reduce the problem of sound leakage by 90%. The latest bone vibration technology improves the overall sound quality performance of the headphones to make sound more spatious sense, and the sound quality characteristics are more prominent.

The overall body of Hi Runner is made of memory titanium that can self-adjust the contact area. So the headphones give people a good wearing experience and more users are taken into account.

As the core component of the product, the headphones chip plays a key role in the experience of the product. Wissonly Hi Runner are equipped with a Bluetooth 5.0 chip for a more stable connection. They also have 32G of built-in memory which is very important to me. I use the headphones completely as an MP3. They can store 5000 songs, which is crazy!

2.Philips A6606 Bluetooth bone conduction headphones


Recommended reason:

The Philips A6606 that weighs 35g is light and compact in the palm of the hand. With the skin-friendly material on the surface of the body, there is no pressure to wear on the pinna. It is equipped with LED night running lights on both sides of the rear end of the body. It can be worn in night walking and low visibility scenes and illuminate the road behind, so that the people around can perceive your own position and respond in time in the face of emergency situations. The safety factor for outdoor wearing is relatively high. It also supports IP67-rated water resistance and can support 9 hours of continuous music playback time, which is also good overall.


3.AfterShokz OPENRUN PRO Bluetooth bone conduction headphones


Recommended reason:

The body of the Openrun Pro weighs only 26g, and it adopts Qualcomm QCC3024 low-energy chip +PremiumPitch 2.0 improved double suspension vibration transmission system and suspension damping technology, CVC call noise reduction algorithm and double silicon microphone. The battery life lasts for 8 hours, and the charging method is magnetic charging. The charging interface has a liquid residue detection function to ensure that it has a good waterproof performance. Its waterproof grade is IP67, and there is no problem with normal sweat. A short period of rain can be used, but it can't be used for swimming.

4.earsopen SS900 Bluetooth bone conduction headphones


Recommended reason:

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.Nank Runner CC3 Bluetooth bone conduction headphones

Recommended reason:

Runner CC2 is an entry-level bone conduction headset, but its overall performance is very good. The headphone body is made of aviation grade material, which has good flexibility and is not easy to be damaged. The weight of the body is only 28g, combined with skin-friendly food-grade silica gel as the surface material, which brings a skin-friendly and comfortable wearing experience. Its waterproof grade reaches IPX6 level, which can meet the basic life-class waterproof.


Among the above five Bluetooth bone conduction headphones, Wissonly and Philip are my favorites. Their products are of excellent quality. In contrast, if I have to choose one, I will choose Wissonly because it has better cost performance.
