How Do Wireless Bluetooth Bone Conduction Earphones Work and How About Their Benefits?
Apr 13,2023 | David
I am a deep user of wireless Bluetooth bone conduction earphones and I love this new product. I wear them both for running and cycling. Obviously, they're already part of my body and give me a lot of motivation when I'm exercising. However, since this year, I have discovered some bad phenomena, that is, there are many fake wireless Bluetooth bone conduction earphones on the market. They are cheap and of poor quality. This has me stuck when it comes to gifting my girlfriend's birthday. She thought that what I sent was cheap and inferior products, and we almost had a relationship crisis. Therefore, in this article, I want to talk about how to distinguish between real wireless Bluetooth bone conduction earphones and fake wireless Bluetooth bone conduction earphones, the principles, advantages and disadvantages of them, and so on.
How to distinguish real wireless Bluetooth bone conduction earphones from fake ones?
wireless Bluetooth bone conduction earphones rely on bones to transmit sound. Fake ones are actually air-conduction headphones that rely on air to transmit sound. There is a big difference in the way of sound transmission. Fake wireless Bluetooth bone conduction earphones (that is, air conduction headphones), emit sound from two external speakers, and the sound transmits sound through the air into the ear. Therefore, under normal social distance, the sound played by fake wireless Bluetooth bone conduction earphones can be heard by everyone, while with real ones, within the same distance, other people can't hear the sound at all.
You can do a test and put on the headphones. If you wear real wireless Bluetooth bone conduction earphones, you will find that the sound is louder and clearer after the ears are blocked. And if you wear fake ones , the sound becomes smaller after you block your ears.
How do wireless Bluetooth bone conduction earphones work?
To understand how wireless Bluetooth bone conduction earphones work, you need to understand how the ear works.
The ear is divided into the outer ear, middle ear, inner ear, and auditory nerve from front to back. The outer ear is what we call the part of the ear that is visible from the outside. When sound enters the outer ear, it travels directly to the eardrum, and the sound that hits the eardrum vibrates the air in the middle ear like a drum, causing the air to vibrate and travel to the cochlea of the inner ear. Shaped like a snail, the cochlea contains lymph fluid and sound-sensing cells called hair cells. The vibration of the eardrum causes the lymph fluid and hair cells in the cochlea to vibrate. Hair cells convert this vibration into an electrical signal and transmit it to the auditory nerve. The auditory nerve carries the electrical signals received from the hair cells to the brain. The center of the brain processes the electrical signals it receives, resulting in the sounds we hear. This way of transmitting sound is the way of air conduction. Our common headphones use air-conduction sound transmission, but the working principle of wireless Bluetooth bone conduction earphones is completely different. It uses bone conduction sound.
We can compare the difference between these two sound transmission methods:
The sound transmission path of air conduction headphones: outer ear → eardrum→ middle ear → inner ear (cochlea) → auditory nerve → brain
The sound transmission path of wireless Bluetooth bone conduction earphones: temporal bone (skull) → inner ear (cochlea) → auditory nerve → brain
Compared with air conduction headphones, the sound transmission path of wireless Bluetooth bone conduction earphones does not have several steps of "outer ear→eardrum→middle ear". When using them, the sound conduction process is that the sound source vibrates and directly transmits the sound to the inner ear (cochlea) through the skull. This working principle also makes the headphones do not need to be inserted into the ear, which better protects the ear canal and eardrum.
What are the benefits of wireless Bluetooth bone conduction earphones
Since wireless Bluetooth bone conduction earphones 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 earphones 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 earphones 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 earphones 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 earphones 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.
In fact, bone conduction earphones are worth buying because they have a lot of advantages,they are safety,healthy,and hygienic.However, how to choose the right headphone is another problem.Here are some excellent bone conduction headphones for you.
1, Wissonly Hi Runner wireless Bluetooth bone conduction earphones
Reason for recommendation:
Wissonly wireless Bluetooth bone conduction earphones, the product I use the most, is the first brand I started to contact. When they were crowdfunding online, I participated.
The sound quality is what I am most satisfied with. I am not a professional music player, but from my personal experience, Wissonly Hi Runner is the best sound quality wireless Bluetooth bone conduction earphones I have ever used. It uses a large-sized 360-degree bone conduction vibration unit, and through structural optimization, the sounding area is increased by 35%, so that the sound range is wider, and the stereo feeling and shock of sound are stronger. Its anti-sound-leakage treatment is also very good. The whole body is completely sealed, and the algorithm is optimized to minimize the leakage of sound. I have tested it myself, and at a distance of 2 meters, the volume is turned on at 60%, so I can't hear the sound at all.
wissonly Hi runner’s body is made of memory titanium, which can self-adjust the contact area. It can ensure a good wearing experience of the earphone at any time, taking into account more users and usage scenarios.
Wissonly Hi Runner is equipped with Bluetooth 5.0 chip, and the connection is more stable. It also has IPX8 professional sports waterproof +32g internal memory to swim in the water. The battery performance is also good, and it can play music continuously for 8-10 hours.
