What is The Difference Between Air Conduction and Bone Conduction Headphones?
As more and more people realize the harm of in-ear Bluetooth headphones, bone conduction Bluetooth headphones has become a new choice. At present, this field has just begun. On the one hand, many small factories can’t break through the technical barriers of bone conduction; on the other hand, the long research and development cycle of the field requires a certain scale of investment. Therefore, many brands have just started in the field. Because bone conduction headphones are becoming more and more popular, some dishonest manufacturers directly take out the semi- finished products like air conduction or pseudo-bone conduction and come out to pretend them to be bone conduction headphones, which also makes many people who don’t know much about bone conduction be deceived. I hope this article can help you deepen your understanding of this type of headphones and decide whether you are suitable for them according to your own actual situation.Through in-depth discussion of the characteristics of bone conduction headphones, we can help you choose these products scientifically
Difference between air conduction and bone conduction headphones Under normal circumstances, all the sounds we hear need to pass through our ears. The ears sense the vibration of sound waves, convert them into sound signals, and pass them to our brain, and then parses them into the sounds we hear. Whether it’s common wired headphones, Bluetooth headphones and noise-reducing headphones, they all belong to “air conduction headphones” in essence, that is, vibrating air and transmit sounds to our eardrum,and vibrate and drive other organs such as ossicles to transmit sound to our brain.
Bone conduction is the direct use of human bones as the medium for sound transmission. For example, In daily life, we hear the sound of teeth colliding and scratching our heads, which is actually the sound of bone conduction. Bone conduction does not need ears to collect sound, not need ear canal to transmit sound ,It doesn’t even require eardrum vibration.This sound transmission method saves the work of these organs and directly transmits sound to auditory nerve through bones. It has a very prominent point, that is, the sound transmitted by bones is less irritating to auditory nerves, so this is the reason why bone conduction can relieve auditory fatigue and avoid hearing loss. The unique sounding principle of bone conduction headphones can effectively avoid various ear diseases caused by in-ear headphones.So this type of headphone has been recommended by otologists and audiologists.
How to distinguish true and false bone conduction headphones? After understanding the difference between air conduction and bone conduction headphones, it is much easier for us to judge true and false You only need to observe whether the sound unit of the headphones is sealed and whether there is a sound outlet, so you can make a good judgment. Because the bone conduction headphone vibrates and transmits sound by the internal bone vibration unit, its sound generating unit is completely sealed. Most pseudo-bone conduction devices only have a built-in speaker, and in order to transmit sound, it must have a sound outlet in the body.
If you still can’t understand this, the easiest way to identify it is to put on headphones to block your ears. The sound of bone conduction headphones will become louder, the sound quality will become better, the stereo effect will become stronger.The sound of false bone conduction headphones will become smaller, and the sound quality will become blurred while blocking your ears.
I try to use the most popular language to popularize bone conduction headphones, hoping to help you choose a good product. If you still don’t know how to choose bone conduction headphones after reading the above popular science content, then let me recommend some for you.
- Wisonly Hirunner bone conduction headphones
Recommended reason:
When Wissonly Hi Runner started crowdfunding online, I started to pay attention to them. Later, I saw on some online forums that all otologists were recommending them, so I bought it. This Hi Runner is their flagship product, and its overall function is the most perfect. This headphone uses the latest research results of wissonly Lab. It effectively increases the vibration area of the vibrator by 35%, while optimizing the sound transmission direction, making the sound range wider and the music more spatial. The brand claims to reach the HI-FI sound quality. My own actual test shows that the sound quality is very close to the HI-FI level, but it doesn’t reach this level. Of course, the current sound quality is satisfactory enough.
Wisonly Hi Runner bone conduction headphones are also equipped with a new Bluetooth 5.0 chip, which has stronger anti-interference ability, and can easily cope with various outdoor complex scenes, so as to ensure that the good mood during exercise will not be disturbed by disconnection. The stable connection also brings ultra-low delay performance while listening to songs, chasing dramas and playing games ,it meet all the daily use. What’s more, it has 32G built-in memory, which can store 5,000 songs and helps you to enjoy music without your mobile phone when you are outdoors.
Wissonly performs well in terms of comfort. It’s very light, less than 30g, and you don’t even feel like you’re carrying it when you wear it. The body is made of titanium alloy, which makes it fit well. You don’t need to worry about falling off during exercise.
The waterproofness of Wissonly Hi Runner needs special mention. It reaches IPX8 grade, which means that you can carry it under water for 20 meters and still use it normally. This is crazy!
- AfterShokz OPENRUN PRO bone conduction headphones
Recommended reason:
The main body of the Openrun Pro is an ear-hanging structure worn by both side of the ears, but thanks to the light materials such as titanium alloy used in the basic frame of this headphone, the overall weight of it is only26g. It is worth mentioning that this headphones has IP67 waterproof and dustproof grade, which can be rinsed and washed with water. In addition to the coating process on its surface, of course, Openrun Pro is structurally waterproof in the Integrated body design. In addition, it also uses a double silicon microphone. On the right side of the headphones, you can see the microphone opening reserved by the headphones for the microphone. It is equipped with CVC noise reduction algorithm, it can effectively eliminate the call effect in complex environment.
- Philips A8606 bone conduction headphones
Recommended reason:
Philips A8606 is designed as an ear-hook headphone, and its ear hook is made of titanium alloy, which has the characteristics of good elasticity, high strength, wear resistance, etc., and the overall hand feeling is also very light. In terms of waterproof performance, A8606 supports IPX5 waterproof certification, which can adapt to daily use. A8606 uses the mainstream
Bluetooth 5.0 technology, which has the characteristics of low latency, low power consumption and stable transmission. It has strong adaptability and quick connection, and at the same time, the signal in this is stable, and there has never been a stuck situation. Its disadvantage is that its sound quality needs to be improved, and the sound leakage is also serious.
- Nank runner cc2 bone conduction headphones
Recommended reason:
Runner cc2 is an entry-level headphones ,it has relatively simple functions, but it is also enough to meet daily needs. Runner cc2' s weight is only 28g, so it won’t be felt heavy when it is hung on ears, and never cause swelling or squeezing when worn for a long time. The headphones can link quickly and the signal is stable, and the linkable range is about 10 meters. In terms of waterproof ability, it has reached IPX6 level, and daily waterproof and sweat prevention are basically no problem.
