Mar 14,2023 | David
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. 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. 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, bone conduction headphone is a new application of this mature technology, and you can use it with confidence;
6. 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. 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.
8. They will have a slight sound leakage problem. But some better products handle sound leakage better.
What are the side effects of bone conduction headphones?
Many people think that Bluetooth bone conduction headphones have side effects. Some people think that they are harmful to the body because they vibrates the bones to hear the sound which will affect the brain. However, this statement is not accurate. The side effects of bone conduction are very low. The following will clarify the rumors about the side effects of bone conduction one by one.
Side Effects of Bluetooth bone conduction headphones 1: Hearing Damage? rumor!
Bluetooth bone conduction headphones are the most hearing-protective of all headphones. Because the way of bone conduction transmits sound does not need to pass through the eardrum, which can avoid damage to the eardrum. And its vibration waves are very gentle, and the impact on the cochlea is relatively small.
Side effects of Bluetooth bone conduction headphones 2: damage the brain? rumor!
Some people think that the electromagnetic waves of Bluetooth bone conduction headphones will cause damage to the brain nerves. Of course, any electronic product has problems with electromagnetic waves, and strong electromagnetic waves will indeed cause damage to the brain nerves. However, the electromagnetic waves of Bluetooth bone conduction headphones are extremely weak and have the same strength as the electromagnetic waves existing in nature. So it will not cause damage to human brain nerves and hearing nerves.
Side effects of bone conduction earphones 3: Pain after wearing for a long time? Inaccurate!
It is indeed uncomfortable to wear Bluetooth bone conduction headphones for a long time. Long-term wearing here means that the sound unit is attached to the temple and worn for more than 3-4 hours. Usually, there will be no problem wearing it for less than 2 hours. Because even traditional over-ear headphones can be uncomfortable to wear for hours on end.
In addition, some people mentioned that wearing Bluetooth bone conduction headphones for a long time, caused pain in the temples. This situation has a lot to do with the individual's physique - it is the individual's physique that causes trigeminal neuralgia.
Therefore, we can know that the side effects of Bluetooth bone conduction headphones are very low. It is a very healthy headphone.
In addition to being very healthy, Bluetooth bone conduction headphones have many advantages, such as safety, comfort, high waterproof level, etc. These advantages determined by their working principles
How do Bluetooth bone conduction headphones work?
The propagation medium of sound includes solid, liquid, and air. In general, there are two ways for sound waves to enter the inner ear of the human body: air conduction and bone conduction. It then travels to the inner ear via the auditory ossicles. Bone conduction is the vibration of sound waves through the bones of the head such as the skull and jaw, which transmits the sound to the inner ear. It is another very important hearing method besides air transmission. People use this method to manufacture many bone conduction hearing devices.
Traditional headphones mainly transmit sound through the air, while Bluetooth bone conduction headphones use the temporal bone of the head to transmit sound. It transmits sound directly to the auditory nerve in the form of sound waves, instead of passing through the air to the eardrum and then to our auditory nerve.
Currently, bone conduction hearing devices mainly include electromagnetic Bluetooth bone conduction headphones and piezoelectric bone conduction headphones. Electromagnetic Bluetooth bone conduction headphones have better working performance, but they have electromagnetic radiation, which is easy to cause harm to the user's body. Piezoelectric Bluetooth bone conduction headphones use piezoelectric vibrators as sounding components. When people wear it the human body is less affected by electromagnetic radiation which also has the advantages of small size and low power consumption.
If you are interested in them, please do not hesitate to buy them. They are definitely worth buying.Next, I will recommend some excellent bone conduction headphones.
1, Wissonly Hi Runner bone conduction headphones
Wissonly 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 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 bone conduction headphones, and the Wissonly Hi Runner has currently the best sound leakage reduction solution in 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. Wissonly 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.
