Apr 06,2023 | David
Wireless Bluetooth bone conduction headphones are becoming more and more popular among sports enthusiasts. Driven by them, more and more people are interested in this new type of headphones. To help you better understand them, here are some facts about this type of headphones.
1. Wireless Bluetooth bone conduction headphones are new headphones developed using bone conduction technology, which transmits sound through bones;
2. They do not cover the ears, nor do they need to be inserted into the ears;
3. They will not damage the ears, they are the healthiest headphones for the ears. Because their sound transmission does not require the use of the eardrum, damage to the eardrum and auditory hair cells is minimal.
4. Wireless Bluetooth bone conduction headphones are not noise-canceling headphones. They don't sound as perfect as traditional noise-canceling headphones. But if you're using them for normal music listening, their sound quality is perfectly fine.
5. Bone conduction is a mature technology, wireless Bluetooth bone conduction headphone is a new application of this mature technology, and you can use it with confidence;
6. Wireless Bluetooth bone conduction headphones are not headphones with external speakers. It relies on the vibration unit to generate mechanical vibrations, and the sound is transmitted to the inner ear to make people hear the sound.
7. Wireless Bluetooth bone conduction headphones generally have better waterproof performance. Their sound generation and sound transmission methods make them not need to reserve holes in the fuselage, and the entire headphone can be integrated.
How do wireless Bluetooth bone conduction headphones work?
Let's start with a story. Beethoven was a great composer, and he is still loved by many people with representatives such as "Fate Symphony", "Eroica Symphony ", "Ode of Joy Symphony " and so on. In fact, Beethoven suffered from hearing impairment in his later years. Even in this state, he continued to compose, which is a bit bizarre. How did he do it? When playing, Beethoven held his baton in his mouth and put the other side on the piano,and then hear the sound.. This was the earliest application case of bone conduction.
In Beethoven's case, the vibrations caused by the piano as a source of sound are transmitted through the baton to the jawbone on the side of the mouth, and then from the frontal bone to the inner ear, which eventually formed hearing.
You may have found that the entire sound transmission process was the participation of solids such as batons and bones, without the participation of air and the eardrum. This seems to be a little deviated from our daily cognition. If we look through the physics books in middle school, we could know that there are three mediums for sound transmission: namely air, liquid and solid. Human bones are solids, and of course, they can also act as a medium for transmitting sound.
With the above knowledge, it would be easy for us to understand how wireless Bluetooth bone conduction headphones work.
Wireless Bluetooth bone conduction headphones are a type of headphones manufactured by using bone conduction technology. Bone conduction is a sound conduction method with bones as the medium. It converts sound into mechanical vibrations of different frequencies to transmit sound waves through the human skull, bone labyrinth, inner ear lymph, spiral organ, and auditory center.
When they work, you only need to put the sound unit close to the temple, do not need to stuff them into the ear canal. They are good to the cleaning of the ear canal, and cause no harm to the eardrum.
What are the benefits of wireless Bluetooth bone conduction headphones
Since wireless Bluetooth bone conduction headphones do not require the use of both ears, they also bring some health benefits. They do not need to be stuffed into the ear when worn, they can keep the inside of the ear canal clean and hygienic. And the surface of them is smooth, easy to clean, and its body can keep clean. Traditional air conduction headphones are worn either into the ear or covering throughout the ear, which will cause bacteria to deposit inside the ear. So wireless Bluetooth bone conduction headphones are of great help to the ear health. They use the principle of bone conduction to transmit sound that does not need to pass through the eardrum. So unless the volume is turned up too much, normal volume will not affect hearing when the headphones are used.
Wireless Bluetooth bone conduction headphones are also very friendly to be used in sports scenes. Wireless headphones themselves are sport-friendly, and the non-in-ear characteristics make them more suitable for sports scenes than other headphones. They are also much more stable in wearing than traditional wireless Bluetooth headphones. Their integrated body structure is tightly fastened to the temples on both sides,and no matter how you move, they will firmly stick to the ears, following the rhythm of your body. So you do not worry about their falling off.
At the same time, wireless Bluetooth bone conduction headphones can provide higher safety and security compared to common headphones. They are placed on the cheekbones in front of the ears when used. They directly conduct sound through the skull to the inner ear. Both ears are always open, so the phones will not affect any external environmental sounds into the ears. Users can even listen to music while chatting with friends around them. Therefore, in outdoor occasions, on the bus and subway, and when walking on the road, you can hear the sound of outside world, so as to avoid accidents.
Of course, wireless Bluetooth bone conduction headphones are not 100% perfect, and they also have some disadvantages. For example, their sound quality is not as good as that of traditional noise-canceling headphones. For example they have problems of sound leakage. Fortunately, the entire industry is working hard to solve these problems. And some excellent brands, such as Wissonly and Aftershokz, have improved the sound quality and sound leakage perfectly.
It can be said that wireless Bluetooth bone conduction headphones are good for using, and the following i will recommends several good headphones to everyone.
1, Wissonly Hi Runner wireless Bluetooth bone conduction headphones
This is the fastest growing brand in the past six months. It may not be much famous, but in the field of wireless Bluetooth bone conduction headphones they are proper technical experts. Their team began to develop wireless Bluetooth bone conduction headphones that do not hurt the ear as early as 10 years ago. With an excellent bone conduction vibration unit optimization program, It became famous very soon in the field of bone conduction. It has been recommended by the majority of otologists!
Due to the particularity of the technical principle, wireless Bluetooth bone conduction headphones are more difficult to be improved in sound quality. Wissonly Hi Runner team subverted the traditional sound quality scheme, made a breakthrough to use large wire-frame vibration unit. They through structural optimization improved the effective vibration area, thereby improved the vibrator sound efficiency, made the sound more shocking and powerful, they optimized the sound transmission direction, reduced the sound loss during sound transmission, and made the sound quality more concentrated. In terms of comfort, the overall body of the Hi Runner is made of high-tech hypoallergenic silicone material, which does not contain chemical components to avoid allergies. The overall feel is as silky as baby's skin, avoiding uncomfortable wearing for a long time.
