Can others hear bone conduction headphones and The Method of Improving Sound Leakage in Bone Conduction Headphones

Let's start with the conclusion:Others can heard bone conduction headphones, which is the phenomenon of sound leakage! But good bone conduction headphones have very little sound leakage! "The severity of sound leakage can reflect from the side whether the bone conduction headphone is excellent."

As we all know, transmitting sound needs a medium. Sound can not be transmitted in the vacuum environment, because there is no air as a medium in the vacuum environment.When we speak, or wear headphones to listen to music, or listen to music on the stereo, sound are transmitted through the air.

When listening to songs on the stereo, everyone around can hear them, but you can enjoy a private space with headphones, without fear of disturbing others or divulging your own privacy. But do you know that common headphones also have sound leakage? Because the headphones themselves transmit sound by air, through the vibrating of air, air vibrating eardrums to let you hear the sound. The reason why we can't feel the sound leakage is because that the sound generating unit of the headphones is very close to our eardrums, the sound is very small, and it is still wrapped in the ear, so you can't feel the sound leakage.

Although bone conduction headphones vibrate bone to transmit sound, The sound generating unit is a "vibrator", not a "loudspeaker". But when the vibrator vibrates our bones, the shell of the headphone will also vibrates the air near it. Because the bone conduction headphones are exposed to the air, there is no advantage of common headphones being wrapped in ears, and the problem of sound leakage occurs. Therefore, bone conduction headphones will leak sound, but the degree is different. Excellent bone conduction headphones are better in the anti-leakage sound, almost do not feel the leakage.

*Is there a solution to sound leakage of bone conduction headphones?
*

Yes! After understanding how the sound leakage occurs, you can find a solution to it. The simplest way to reduce sound leakage is to reduce the vibration of the vibrator and the headphones case to reduce the vibration of the bone conduction headphones. In fact, most manufacturers on the market also do these: choose sealed body and softer shell, reduce the sound leakage caused by vibration. But this alone is not enough, Although the sound leakage is not as loud as the loudspeaker, it can still be heard at a distance of two meters.

Later, in order to reduce sound leakage,some bone conduction headphones brands began to use more advanced "vibrators" to reduce from the source of sound generating . Through the software algorithm, cancel the noise on the headphones. But at present, bone conduction headphones are in a popularization stage. Although there are more and more brands, only a few brands own core technology.The current brands with better sound leakage reduction are wissonly and Aftershokz. Just like Wissonly Hi Runner bone conduction headphones in my hand, they claim to be able to reduce 90% of the sound leakage. I tested myself and found that at 70% of the volume, the sound can not be heard outside the headphones at an distance of 1 meter I am very satisfied with its performance.

Here are some bone conduction headphones with better sound leakage reduction for you.

*1 Wissonly Hi Runner bone conduction headphones

This is the fastest growing bone conduction headphone brand in the past six months. The team are all engineers with 10 years of experience in the field of bone conduction technology. They began to develop bone conduction earphones that do not hurt ears as early as 2012.

In order to solve the problem of sound leakage of Bluetooth bone conduction headphones, wissonly has made comprehensive improvements in the vibrator, headphones body design, software optimization and other directions of the headphones. The final result is applied to Wissonly Hi Runner. In laboratory testing, the final sound leakage can be reduced by 90%. I actually used headphones and tested myself. At a distance of 1 meter, I still did not hear the sound of bone conduction headphones when the volume reached 70%, which protected my privacy very well.
The body of the Wissonly Hi Runner is made of titanium, which can self-adjust the fitting position, ensuring that the headphones have a good wearing experience and Match more people's head circumference. As the core component of the product, the headphone chip plays a key role in the experience of the product. The Hi Runner model is equipped with a Bluetooth 5.0 chip, which makes the Bluetooth connection faster and more stable. It also has 32GB of built-in storage, and you can use it as an MP3 player.
The other features of the Wissonly Hi Runner are also excellent, such as the IPX8 waterproof, and you can wear it to swim and even dive. The battery lasts 8-10 hours, which is important for me. Because I go out for sports on weekends, and I usually go out all day.

*2 AfterShokz Openrun PRO bone conduction headphones


The first feeling of AfterShokz Openrun PRO is that the weight is very light, almost let you forget its existence. In terms of battery life, the continuous playback time can exceed 8 hours. It can be said as a very powerful bone conduction headphone. The AfterShokz brand is mainly developed for sports. The only drawback is that the vocal unit is made very slender, and it will be a little oppressive to wear it for a long time.
In terms of function, it has IP67 waterproof coefficient, It can be worn for daily outdoor sports without fear of sweat and can also be washed.

*3 earsopen PEACE bone conduction headphones

Born in Tokyo, Japan, earsopen is a bone conduction headphone brand from BoCo Co., Ltd. The earsopen PEACE TW-1 is the first Bluetooth headset with left and right separation among bone conduction products. Because the vocal unit is small and closer to the ear canal, the sound leakage is also very small. It uses a separate design for the first time in the bone conduction industry. The headphone body is a T-shaped design, using the ear-clip type wearing method. The comfort is not as high as the first two, but this way of wearing is really unique. If you must choose TWS, this one is really good.
