How Does The Sound Leakage of Bone Conduction Headphones and Recommendations for Headphones with Minimal Sound Leakage
Dec 15,2022 | Sylvia
First of all, it should be noted that bone conduction headphones do leak sound, which is also a common problem of them. However, the sound leakage phenomenon can be improved through technology. For example, some good bone conduction headphones have reduced sound leakage by 90%, which is almost equal to no sound leakage.
To understand why bone conduction headphones leak sound, we need to understand the working principle of them.
Sound is a wave phenomenon that the sound wave generated by object vibration propagates through the medium (such as air or solid, liquid) and can be perceived by human or animal hearing organs.
Generally, sound waves are transmitted to the inner ear through the external auditory canal, tympanic membrane and auditory ossicles in turn, causing excitation signals to the sensory organs of the inner ear, transforming sound energy into nerve impulses, and then passing through the auditory nerve to the brain center, thus producing hearing.
Common headphones, whether on-ear headphone or in-ear earphone. Their principle is that the air in the external auditory canal acts as the medium of sound transmission.It transmit sound waves through the eardrum to the ossicles and then to the inner ear. However, bone conduction headphones use the skull as a medium to transmit sound waves directly to the ossicles and then to the inner ear, bypassing the external auditory canal and eardrum.
So, why does the bone conduction headphones leak sound?
If there is vibration, there will make sound. While bone conduction headphones transmit sound to the skull, the vibration of the shell will also transmit sound to the air, which is commonly known as sound leakage.
It should be emphasized that some headphones so-called "bone conduction headphones" with serious sound leakage are actually air conduction headphones, which just look like bone conduction headphones. It is made by two loudspeakers beside its ears. In order to let the ears hear the sound, its speakers are loud. So the sound leakage is very serious.
In fact, the real bone conduction headphones also have the problem of sound leakage. However, at normal volume, the sound leakage problem is not serious, and there will be no personal privacy problem. Moreover, as the technology of bone conduction headphones becomes more and more mature, the phenomenon of sound leakage of bone conduction headphones can be reduced through technological progress. Some brands with core technology in the field , such as Wissonly and Afershokz, are outstanding in in reducing sound leakage . They all have their own bone conduction technology and are the best in terms of sound quality and sound leakage reducing.
Here are some bone conduction headphones worth buying for you below. Some of them with minimal sound leakage
1、Wissonly Hi Runner bone conduction headphones
Reason for recommendation：
Wissonly is a leading brand in bone vibrator technology. It has mastered the core technology of bone conduction. Their products are famous for their good sound quality, less sound leakage and health and safety.
Wissonly Hi Runner bone conduction headphones adopt full closed body and sound loss reduction technology. Its fully closed body can reduce the problem of sound leakage by 90%, which almost perfectly solves the problem of sound leakage of bone conduction headphones. In addition, it also uses a new directional vibrator technology to improve the effective vibration area, thereby improving the sound quality of the headphones, making the spatial sense of sound stronger and the sound quality better.
Hi Runner is very comfortable to wear. Because its appearance material is high-tech low sensitive silicone material, and it is very light. Even if it is worn for a long time, it will not bring any burden to the ears.
Wissonly Hi Runner is also equipped with a new Bluetooth 5.0 chip, which has stronger anti-interference capability and more stable connection. It also has 32GB of built-in storage, which can store 5000 songs. Even when there is no signal, it is excellent to be an MP3 player. It must be emphasized that its waterproof performance has reached IPX8. It can be used normally in swimming and diving.
2、Aftershokz Openrun Pro Bone conduction headphones
Reason for recommendation:
Aftershokz is a brand focusing on bone conduction technology. It has won the favor of many consumers with its advanced technology and full titanium design. The headphones are ergonomically curved, more fitting to the ears, and have high overall comfort. The headphone has made an ergonomic arc processing, which makes it more suitable for the ear and has high comfort. In terms of sound leakage, Openrun Pro uses the newly upgraded PremiumPitch2.0+technology to optimize the sound transmission direction without sound leakage. Every aspect of this headphone's performance is very good, but the price is a little high.
3、NANK Runner CC2 Bone conduction headphones
Reason for recommendation:
The body of Runner CC2 is made of titanium alloy. Its body weight is only 28g, making the wearing experience good. Full marks for this aspect. The sound quality and leakage are better than their previous products, but they still need to be improved. The headphones also supports high-definition call noise reduction, which is a plus.
This headphones has average capacity. It is not particularly brilliant and has no particularly obvious shortcomings. As an entry-level bone conduction headphones, it is qualified.
4、Philips A6606 bone conduction headphones
Reason for recommendation:
This Philips A6606 bone conduction headphones is designed with a comfortable silicone fit, which is very comfortable to wear. It conforms to the ergonomic design, and can be worn firmly without dropping. It has reached IP67 deep waterproof grade. It is not a problem to sweat profusely during daily exercise. This headphones also has a night running light, which is bright enough. When running at night, people or vehicles can notice you. Its body is equipped with Bluetooth 5.2 technology. Compared with 5.0, it has farther transmission distance and lower power consumption. However, this one can't be used for swimming.
The above recommended bone conduction headphones are cost-effective. I hope it can help you. As for which headphones to choose, you can make a choice according to your needs and positioning.
