What Is Bluetooth Bluetooth bone conduction headphones and How Do They Work?
Mar 11,2023 | David
In daily life, the sound of teeth colliding can be clearly heard by us, but people around us cannot hear it. This is probably the nearest case of bone conduction technology around us. When you collide your teeth, you may hardly imagine that this sound transmission method will be applied by talented engineers to create the latest popular product-bone conduction earphones.
what are Bluetooth bone conduction headphones?
Bone conduction headphone is a type of headphone using bone conduction technology. Its biggest feature is that it uses bone conduction to transmit sound, uses human bones as the medium for transmitting sound, and directly transmits sound to the auditory nerve to form hearing.
This distinctive technical feature has also revolutionized the way it is worn. The wearing method of Bluetooth bone conduction headphones has changed from traditional in-ear wearing to hanging ear wearing. When wearing it, you only need to hang the earphone on the auricle and put the vibration unit close to the temple, and the whole ear is completely open. The change in the way of sound transmission and wearing has made Bluetooth bone conduction headphones another type of earphone, which is a huge upgrade compared to traditional earphones. Many ear doctors also highly recommend them, because they are better and healthier for ears.
How do Bluetooth bone conduction headphones work
Bluetooth bone conduction headphones are a product that "attaches the sounding unit on the temple of the head, and the vibration of the sounding unit triggers bone vibrations, thereby transmitting the sound to the auditory nerve".
Normally, when the air vibrates, the eardrum vibrates and a person perceives sound. It needs to be clarified that it is not the eardrum that really feels the sound, but the cochlea. The eardrum is only one step in the sound transmission process. Vibrations of the eardrum are transmitted through the ossicles to the cochlea at the back of the ear where they are perceived as sound, which is how air conducts sound.
In the process of air conduction sound, there is a medium that is listening to the ossicles. So, is it possible to transmit sound directly from bones? It's possible, and it's real. The vibration caused by the sound unit drives the bones around the ear to resonate so that the sound signal is transmitted to the cochlea, which is perceived as sound by people. This is the principle of bone conduction technology.
After understanding the way sound is transmitted and the principle of bone conduction technology, we can better understand how Bluetooth bone conduction headphones work. When they are in working condition, as long as the sounding unit is pasted on the temple, the sounding unit converts the sound signal into mechanical vibration, drives the bone to vibrate, and transmits the vibration signal to the auditory nerve in the cochlea, thereby completing the transmission of sound. This is how Bluetooth bone conduction headphones work.
Therefore, Bluetooth 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.
Next, I will recommend some excellent bone conduction headphones for you all.
1. wissonly Hi Runner Bluetooth bone conduction headphones
Wissonly's core team is a team engaged in the research and development of bone conduction products earlier. They have accumulated 10 years' technology in this field. They have adopted the best acoustic laboratory in the Eastern Hemisphere for sound adjustment. Wissonly Hi Runner has good technical solutions to the problems of sound leakage, sound quality and waterproof of pseudo-Bluetooth bone conduction headphones.
Wissonly bone conduction vibrator adopts a unique full-wrapped design, which makes the vibrator work in a closed environment, reducing the impact on the shell, thus reducing the vibration of the shell and finally reducing the sound leakage by 90%.
Wissonly uses a large-size bone conduction vibrator, and the effective vibration area of the vibrator is increased by 35% through structural optimization. At the same time, the sound transmission direction is optimized, the sound loss is reduced, and the sound is more concentrated.
Wissonly Hi Runner adopts integrated molding technology, with no holes in the headphones’ body and it is no splicing, which realizes IPX8 waterproof, and can be used for swimming and bathing. Even in the depth of 20 meters, diving is no problem.
It also has 32G of built-in memory, which can store 5000 songs. You can use it as amp3 player when you don't have a mobile phone.
In a word, Wissonly Hi Runner is a product with powerful functions, stable technology and high cost performance.
2.Philips A8606 Bluetooth bone conduction headphones
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 Bluetooth bone conduction headphones
Openrun Pro Bluetooth bone conduction headphones are worn in an ear-hanging structure with both ears. The body frame is made of titanium alloy, which makes the weight of the headphones very light, only 26g, and there is no sense of weight when wearing them. The body is made of soft and skin-friendly silicone material, which also makes it more comfortable to wear. As the body is integrated, this also makes Openrun Pro inherently has a good waterproof performance. Its waterproof rating reaches IP67, and there is no problem in sweating and getting wet in the rain. However, it is not professional waterproof after all. Therefore, it can't be used when swimming.
4.earsopen PEACE TW-1 Bluetooth bone conduction headphones
The earsopen PEACE TW-1 headphones can be charged magnetically through the charging case, which is small and convenient to carry around. The headphone shape adopts separate design that is achieved for the first time in the bone conduction industry. The headphone body is a T-shaped design, that adopts the clip-on wearing method. At the same time, it also supports IPX7 waterproof performance. When traveling on rainy days or running to burn fat, there is no need to fear sweat and rain erosion, it can be used with peace of mind.
The T-shaped structure design of earsopen PEACE TW-1 adopts the form of wearing behind the ear with curved support frame. It is more comfortable when worn. But because of the wearing method, the pinna will be a little uncomfortable after wearing for a long time. The sound quality is average, and there is a little sound leakage. But as an innovative style in the bone conduction category, it is also worth considering.
5.Nank Runner CC3 Bluetooth bone conduction headphones
Since the body of the runner CC3 is made of silicone material in the part that fits the skin, wearing it has a feeling of summer coldness, which can fully stimulate the fans of sports.
Its sound quality is not a big problem, and it has built-in 4G storage, which can store 1000 songs. And you could enjoy music in places when meet poor phone signal. The wearing comfort and stability are not bad.
It is that the waterproof level is not high enough, and it is not suitable for rain or water sports.
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.
