Can Others Hear The Sound from Bone Conduction Headphones and How to Improve Sound Leakage?
Feb 03,2023 | Sylvia
Have you ever heard music with headphones on while walking on the road, when the car behind you honks to remind you, everyone around you heard it, but you didn’t know it; or when you listened to music while wearing headphones in the office at work, even if your boss yells next to you, it can't wake up your ears that were kidnapped by music. These awkward moments happen a lot in life, and they're always unpleasant. However, there is a kind of headphone that can perfectly help you avoid these embarrassments, that is bone conduction headphones that have become popular in recent years.
Can others hear the sound from bone conduction headphones?
Under normal volume, with a social distance of more than 1 meter, it is difficult for others to hear the sound of bone conduction headphones. Therefore, the privacy protection of the headphones is still good, and you can use them with confidence.
The reason why some people worry that "others will hear the sound of bone conduction headphones" is mainly because the headphones generally have the problem of sound leakage. However, due to the advancement of technology, mainstream bone conduction headphone brands have solved the problem of sound leakage well. Under normal social distance, your privacy is still guaranteed.
From the point of view of the working principle of sound, all bone conduction headphones have the problem of sound leakage. Because they rely on the vibration of the sound unit to generate vibration waves, and drive the bone to vibrate to transmit the sound to the inner ear, so that it can be heard by people. Therefore, when the headphones are working, their shells will vibrate together with the sounding unit, and the shells will drive the air to vibrate, resulting in sound leakage. For the same headphone, when the volume is higher, the sound unit vibrates more, the air vibrates more, and the problem of sound leakage will be more serious.
How to improve sound leakage of bone conduction headphones?
Excellent bone conduction headphone brands have made a lot of efforts to solve the problem of sound leakage of headphones, and mainly adopted the following methods to reduce the problem of sound leakage.
Integrated body: The headphones body is designed as an integrated body without holes, so that there is no air in the body, and the air vibration caused by the sound unit is also reduced;
Shock-absorbing design of the body: through structural optimization, the shock-absorbing function of the body is improved, and the vibration of the body caused by the vibration of the sound unit is reduced;
Inverted-phase sound wave: The anti-phase sound wave is used to cancel the sound wave of the sound leakage, thereby eliminating the sound leakage.
It should be said that their efforts have paid off. The sound leakage problem of some excellent brands of bone conduction headphones has been well resolved.
Although bone conduction headphones have the problem of sound leakage, it has to be said that they have several outstanding advantages: they allow you to keep your attention on the ambient sound while listening to music, which is very safe; they will not hurt your ears, can Keeping the ear canal hygienic and more. These advantages are why they have become popular.
Now I will recommend some excellent headphones for you.
1. Wissonly Hi Runner bone conduction headphones
This is the fastest growing brand of bone conduction headphones in the last six months. The team are all engineers with 10 years of accumulation in the field of bone conduction technology. They started to develop bone conduction headphones that don't hurt ears as early as 2012. To solve the problem of sound leakage of bone conduction headphones, wissonly has made comprehensive improvement in the aspects of vibrator, body design and software optimization. The final result has been applied to Wissonly Hi Runner, and the final sound leakage can be reduced by 90% after laboratory test. I actually used the test myself. At a distance of 2cm, the volume reached 70%, but I still didn't hear the sound of the headphones, which protected my privacy.
Wissonly Hi Runner’s body is made of titanium, which can self-adjust the fitting position to ensure a good wearing experience for headphones, so that more people can wear it. As the core component of the product, the headphones plays a key role in the product experience. Hi Runner model is equipped with Bluetooth 5.0 chip, which makes Bluetooth connection faster and more stable. It also has 32GB of built-in storage so you can use it as an MP3 player.
Other parameters of Wissonly Hi Runner are also excellent. For example, the waterproof level reaches IPX8, and you can wear it to swim or even dive. The battery life reaches 8-10 hours, which is very important to me, because I go out for sports on weekends, and I go out for a whole day.
2.Philips 7607 bone conduction headphones
Its sounding unit adopt a large-size vibrator of 17mm, which makes it have the effect of high, medium and low triple-frequency balance in sound quality performance. The low-frequency dive is sufficient, the medium and high frequencies are clear and not harsh, but there will be some missing sounds. It is also equipped with an intimate LED night run lamp at the rear end of the body, which can turn on the LED by turning on the key three times in a row. It also has three modes, which is suitable for wearing at night, so that people around it can perceive their own position and ensure their own safety factor to a certain extent.Its IPX6 waterproof rating is not afraid of sweat in daily wear.
3.AfterShokz OPENRUN PRO bone conduction headphones
OpenRUN PRO is good at anti-sound-leakage, it uses LeakSlayer leakage cancellation technology to reduce sound leakage. It is equipped with Qualcomm QCC3024 chip that uses 5.0 Bluetooth protocol, that supports dual-device connection, and that performs very well in terms of stability, compatibility, effective range and delay time. It is IP67 waterproof grade, which is enough to allow it to be used in daily life. But you can not wear it to swim in the water. As a high-end bone conduction sports headphones this is still a pity. And it does not have built-in memory, can not be used as an MP3 player.
4.Earsopen peace tw-1 bone conduction headphones
PEACE TW-1 bone conduction headphone is a Japanese high -end headphone product. It is a rare ear-clip headphone on the market. It is directly clipped to the outer ear and worn just like wearing jewelry. Because the weight of its single body is only 8g, even if it is worn by ear clip, there will be no sense of weight bearing. After all, the weight of many earrings also reaches 8g. Of course, there will still be some discomfort when it is worn for a long time.
It adopts Bluetooth 5.0 technology, and the Bluetooth connection is more stable, with few disconnection cases. The sound quality and leak-proof treatment is good, and it is excellent for bone conduction headphones. The only drawback is that the price is a little high. After all, it is positioned as a high-end brand.
5.Nank Runner CC3 bone conduction headphones
Runner CC2 is an entry-level bone conduction headset, but its overall performance is very good. The headphone body is made of aviation grade material, which has good flexibility and is not easy to be damaged. The weight of the body is only 28g, combined with skin-friendly food-grade silica gel as the surface material, which brings a skin-friendly and comfortable wearing experience. Its waterproof grade reaches IPX6 level, which can meet the basic life-class waterproof.
Among the five headphones, my favorite ones are wissonly and Aftershokz. Their technical accumulation is relatively strong and the sound leakage reduction is good. Wissonly has a high cost performance, which is suitable for those with low budget but high requirements for product parameters.
