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 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.
The working principle of wireless Bluetooth bone conduction headphones
Wireless Bluetooth bone conduction headphones are headphones based on bone conduction technology. Bone conduction is a sound conduction method with bones as the medium. It converts sound into mechanical vibrations of different frequencies, and transmits sound waves through the human skull, bone labyrinth, inner ear lymph fluid, spiral organ, and auditory center.
Compared with the classic sound conduction method of transmitting sound waves through the eardrum, bone conduction saves many steps of sound wave transmission, and it can achieve clear sound reproduction in noisy environments, and sound waves will not affect others due to diffusion in the air.
In fact, the working principle of bone conduction is not mysterious. Each of us has experienced it in our daily life. When you eat, you hear the sound of the food being bitten off, but others cannot hear this sound, because the vibration of the food is transmitted to your auditory central nerve through the teeth and bones, and finally the sound is produced. This is an example of classic bone conduction. You can also knock your teeth now. Did you hear the sound? This is the sound passing through your skull to the auditory nerve, which also uses the principle of bone conduction.
How safe are wireless Bluetooth bone conduction headphones?
Wireless Bluetooth bone conduction headphones are a new application of mature technology, and their safety has early been proved.
First of all, wireless Bluetooth bone conduction headphones have very little damage to hearing. We all know that hearing damage generally occurs in the eardrum and inner ear. When we wearing them,sound do not need to pass through the eardrum, so they do not damage the eardrum. Because the oscillation of them is relatively moderate, the headphones also have less effect on auditory hair cells in the inner ear. Moreover, the electromagnetic waves of them are extremely weak that they will not cause harm to human brain nerves and hearing nerves.
Secondly, wireless Bluetooth bone conduction headphones can still keep you paying attention to ambient sounds when worn, which can help you to avoid many accidents. They are not worn into the ear, Whether in running, cycling, walking or commuting, etc., wearing the headphones to listen to songs, you can still hear the surrounding sounds, and can communicate with others normally, so as to avoid the danger caused by not hearing external sounds.
In addition, wireless Bluetooth bone conduction headphones that do not need to be plugged in the ear canal when worn, are very helpful for maintaining ear hygiene. They do not block the ear canal due to sweating for a long time to deposit a large number of bacteria, and so also reduce ear inflammation and other conditions.
Of course, The safety of any product is relative, and 100% safe products do not exist, and so are wireless Bluetooth bone conduction headphones. Under the premise of long-term continuous use at high volume, they still have the risk of hearing damage. This point also needs to be paid attention to when they are used. It should be noted that any headphones will have hearing damage problems when used at high volume for a long time. wireless Bluetooth bone conduction headphones are still the safest and healthiest of all headphones.
Bone conduction headphones are safer than common headphones,and they have a lot of advantages, They are your best sports headphones.So how can you find your most suitable one of them? Let me recommend a few headphones.
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.
