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-wireless Bluetooth bone conduction headphones.

What are wireless Bluetooth bone conduction headphones?

Wireless Bluetooth 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 wireless 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 wireless 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 wireless Bluetooth bone conduction headphones work?

The production of sound is a kind of vibration, and the sound source can cause air, liquid and solid to vibrate.

There are two main types of sound that we usually hear: air conduction sound and bone conduction sound. “Air conduction sound” means that the sound source vibrates and transmit to the ear through the air, and “bone-conducted sound” means that the sound source vibrates transmit to the ear through the bone.

Sounds such as human voices and TV sounds vibrate the air around you. The vibrations are collected by the pinna and transmitted through the ear canal to the eardrum. Sound transmitted to the eardrum is transmitted through the auditory ossicles to the inner ear, where the vibrations are converted into electrical vibrations that are recognized as sound. The sound we hear through this path is “air conduction sound”.

“Bone conduction sound” does not pass through the pinna, external auditory canal (outer ear), or bone ossicles (middle ear). Instead, the sound source vibrates in resonance with the skull, and the skull vibrations are transmitted directly to the inner ear, where the vibrations are converted into electrical signals and perceived as sound. This is how bone conduction works.

Wireless Bluetooth bone conduction headphones are headphones based on bone conduction sound transmission. When they work, they only need to attach the sound unit to the temple. The vibration of the sound source drives the vibration of the skull, and the skull transmits the vibration to the inner ear. The cochlea completes the perception of sound and transmits it. Give the auditory nerve and auditory center, and finally the cerebral cortex allows us to “hear” the sound after comprehensive analysis.

Are wireless Bluetooth bone conduction headphones safe?
We often hear people worry about the safety of wireless Bluetooth bone conduction headphones, but we can promise that they do not harm the human body at all.

First of all, due to the sound transmission method of wireless Bluetooth bone conduction headphones, they do not need to pass through the ear canal and tympanic membrane, which can avoid damage to the tympanic membrane. Moreover, the vibration waves of them are relatively moderate, and the impact on auditory hair cells will be less, so they are the headphones that cause the least damage to the ears.

Secondly, traditional earphones have problems with electromagnetic waves, which can cause damage to the human brain and hearing nerves. The electromagnetic waves of wireless Bluetooth bone conduction headphones are extremely weak, which is the same intensity as the electromagnetic waves existing in nature. So they will not cause damage to the human brain and hearing nerves.

Moreover, wireless Bluetooth bone conduction headphones can help avoid the dangers of wearing them. It does not need to occupy the ear canal when wearing it. In addition to hearing the sound in the headphone, you can also hear the sound of the outside world. Wearing them when crossing the road will not be in danger because you can’t hear the sound of the horn; when you are exercising outdoors, you can also avoid some dangerous situations.

It can be seen that wireless Bluetooth bone conduction headphones are relatively safe, but safety is not absolute. If you use them to listen to music at high volume for a long time, it will still cause damage to the cochlea.

In addition to safety, wireless Bluetooth bone conduction headphones have many advantages, such as comfortable wearing, cleanliness, high waterproof level, etc.

Of course, wireless Bluetooth bone conduction headphones have some drawbacks, the two most prominent being sound quality and sound leakage.Compared with traditional earphones that focus on sound quality, their sound quality is weaker, but this does not mean that their sound quality is poor. In fact, some wireless Bluetooth bone conduction headphones with better quality have very good sound quality.

Sound leakage has always been a common problem with wireless Bluetooth bone conduction headphones, mainly because the vibration of the bone conduction vibration unit drives the vibration of the headphone body, resulting in sound leakage. However, with the advancement of technology, better wireless Bluetooth bone conduction headphones do a good job in preventing sound leakage, and the problem of sound leakage has basically been solved.

For your safety, we recommend that you choose bone conduction headphones with mature technology. They are some excellent headphones below.

1, Wissonly Hi Runner wireless Bluetooth bone conduction headphones

Reason for recommendation:

Wissonly wireless Bluetooth bone conduction headphones are the first brand I started to contact. When they recommended it on the online crowdfunding platform, I noticed it, after saw that many people were recommending, and I bought it. This Hi runner I used for a few months, and the overall performance was better than I expected.

Some wireless Bluetooth bone conduction headphones leak sound, and you know that I take privacy very seriously, so I’m very concerned about anti-sound-leakage technology. Wissonly Hi Runner does a very good job in the field. Its body is sealed, and through structural optimization and algorithm adjustment, its sound leakage is minimized. The official claim they can eliminate 90% of sound leakage. I do not have professional equipment to test, but I have tried and found that at 60%-70% volume, the sound is completely inaudible at a distance of 1.5 meters, which makes me very satisfied. I have actually compared it with other wireless Bluetooth bone conduction headphones, and the Wissonly Hi Runner has currently the best sound leakage reduction solution in wireless Bluetooth bone conduction headphones.

The Wissonly Hi Runner is also particularly comfortable in the wearing experience. Because the material of the whole machine is high-tech hypoallergenic silicone, and it is coupled with the ergonomic design that conforms to the structure of the human ear, so that users will not bring any burden to the ear under long-term wear.

Sound quality as the core performance is undoubtedly worth mentioning. Hi Runner uses a large-sized vibration unit, the sound range is wider, the sound is more three-dimensional and deeper, so the sound quality is undoubtedly very good. And it is also equipped with a Bluetooth 5.0 chip, the connection is more stable. And it will not be disconnected when used, which is a good experience. The Wissonly Hi Runner also comes with 32GB of built-in storage that can store 5,000 songs, so you can use it completely as an MP3 player to enjoy music without your phone when you go out for a run.
