What is The Principle of Bone Conduction Headphones and The Difference Between Bone Conduction Headphones and In-ear Earphones

Bone conduction headphones, as its name implies, is a kind of headphones made of bone conduction technology. Although it sounds like a magic technology, it is not a concept hyped up. Bone conduction technology is supported by solid scientific basis.

Principle of bone conduction headphones

Bone conduction is a way of sound transmission. That is, sound is transformed into mechanical vibration of different frequencies. Then sound waves transmits through human skull, bone labyrinth, inner ear lymph, spiral organ and auditory center.

Compared with the classical sound transmission mode that generates sound waves through the eardrum, bone conduction saves many steps of sound wave transmission. It can realize clear sound reproduction in noisy environment, and the sound wave will not affect others because of its diffusion in the air.

In fact, the principle of bone conduction is not mysterious. Everyone has experienced it in daily life. The clicking sound you hear while eating is an example of bone conduction. Or you can knock your teeth now. Do you hear anything? This is the sound transmitted to the auditory nerve through the skull. It also uses the principle of bone conduction.

Differences between bone conduction headphones and in-ear earphones

The biggest difference between bone conduction headphones and in-ear earphones is that they do not fit into the ear. In-ear earphones are usually air conduction earphones,This is also fundamentally different. The inaudible feature of bone conduction headphones also brings many benefits.

1.Clean and sanitary: We all know that after wearing in-ear earphones for a long time, the ears will be more prone to inflammation, itching, swelling and pain. When wearing in-ear earphones, it is also easy to cause problems such as rapid growth of bacteria in the ear canal, accumulation of earwax, and even cause ear diseases such as otitis media. The bone conduction headphones does not go into the ear. It transmits sound through bone conduction, directly avoiding ear inflammation from the root, which effectively protects the health of the ear.

2.To ensure personal safety: When walking outdoors, once the in-ear earphones are inserted into the ear canal, you can hardly hear the surrounding sound. Bone conduction headphones are different. You can hear the sound of traffic and pedestrians while wearing it, and you can prevent possible dangers in advance.

3.Comfortable to wear: Wired earphones, whose wire harness will shake with body movement. It often interferes with the freedom of body movement. When the headphone harness collides with an object, the collision sound will be transmitted to the ear, which will greatly affect the music experience! Wired earphones are often confused, which is inconvenient to store. Wireless earphones are generally not stable enough to wear. You worry about it falling when you exercise. bone conduction headphones avoid these problems and are comfortable and stable to wear.

Bone conduction headphones do not need to insert the human ear. It can keep the inside of the ear canal clean and sanitary, and avoid ear inflammation. At the same time, the impact on ear hearing is minimized. They are huge differences between bone conduction headphones and in-ear earphones. Compared with in-ear earphones, bone conduction headphones have obvious advantages, which is the main reason why they are becoming more and more popular.

At present, there are not many brands with bone conduction core technology. Therefore, we must be very careful when selecting. Now I will introduce some bone conduction headphones worth buying.

1、Wissonly Hi Runner bone conduction headphones

Wissonly is the fastest growing brand in the last half year. Its core team has more than 10 years of experience in the field. Therefore, their technical strength is very strong. I generally give priority to brands and products with core technologies.

What impressed me most about Wissonly Hi Runner bone conduction headphones is: Its excellent sound quality and sound leakproof. It adopts the newly developed bone conduction vibration unit. They improves the vibration area by 35% through structural optimization, which makes it have a wider range and better sound quality. In terms of sound leakproof of bone conduction headphones, it adopts the full closed sound reducing technology. Its fully enclosed body without holes reduces the sound leakage by 90%. I have measured that when the volume of the headphones is turned on to 70%, no sound can be heard 1.5 meters away from the headphones.

Hi Runner headphones’ body shell is made of high-tech low sensitive silicone material, and it also adopts ergonomic ear fitting design that conforms to the human ear structure. Users will not feel burdened if they wear it for a long time.

Wissonly Hi Runner bone conduction headphones is the flagship product of Wissonly. It supports IPX8 waterproof grade higher than the industry standard. It's fine when you are swimming or diving. It is also equipped with 32G body memory, which can store 5000 songs. You can use it as an MP3 player.

2、Aftershokz Openrun Pro bone conduction headphones

Openrun Pro uses open-ear bone conduction technology, it improve sound quality and reduce sound leakage through PremiumPitch2.0+technology. It also supports IP67 waterproof and sweat proof which can work normally while sweating or raining. Its Bluetooth feature supports multipoint connection. You can switch Bluetooth connections between multiple devices. It has a battery life of 8 hours and supports fast charging. It can be said that on the premise of continuing the advantages of the previous generation of products, it has also carried out a comprehensive upgrade.

3、Philips N6606 bone conduction headphones

The appearance of Philips N6606 is very good, and its strange shape of dark gray has a special sense of technology.. The new rear hanging design is sporty. Its body surface is made of silica gel, which feels smooth, and the interface is also very smooth. Philips's manufacturing process do need to doubt. The body uses waterproof silicone and titanium alloy, so its weight is only 36g. It feels very light to use. Its body frame is made of memory titanium alloy, which can be stretched and bent repeatedly. It is specially designed with night running mode and equipped with 2 LED night running warning lights.
Philips products are still reliable, but the price is a little expensive. Its cost performance ratio is average.

4、MOING bone conduction headphones

MORING headphones is a kind of headphones for students, which is suitable for college students and high school students. For the convenience of carrying, the lightweight body design is adopted, and the weight is only 30g. There is no sense of weight when you are exercising, and the wearing experience is very comfortable. It has a streamlined sunken design. When wearing, it fits both ears for a more comfortable experience.

5、Nank Runner cc2 bone conduction headphones

Runner CC 2 bone conduction headphones have tried their best to reduce sound leakage. The whole headphones adopts seamless design,even the headphones is wrapped with silica gel.It can greatly reduce sound leakage with the unique leak elimination technology.
It uses magnetic charging. After each use, just put the magnetic suction head at the clip position of the headphones. Compared with traditional headphoness, the Runner CC2 bone conduction headphones have no holes in the whole body, which has a certain waterproof effect.
Overall, it is a good entry-level bone conduction headphones. Due to insufficient waterproof level, it is not suitable for rain or water sports.
