Bone conduction headphones, also known as bone-conducting headphones, bone-sensing headphones, bone-passing headphones and bone-sensing headphones, are not a very new concept, after nearly a decade of development, the vast majority of bone conduction headphones on the market today still have unresolved principle problems.
The first point is the problem of adaptation. The principle of bone conduction headphones is to rely on its two vocal patches tightly attached to the ear of the part of the skull, the vibration is transmitted inward to the inner ear lymphatic fluid, auditory nerve and other structures to play a sound role, and this clamping is generally by the two vocal parts in the middle of the ring elastic metal. And different people's skull shape is different, resulting in many people can not reach the tight effect after wearing, affecting the sound volume of the problem.
The second point is the sound leakage problem. As mentioned above, the vibration of the sound patch will inevitably lead to the vibration of the headset body itself, driving the vibration of the surrounding air leading to leakage. This, though vary depending on the volume size of the headset, is inevitable in itself, unless the shell can be isolated from vibration, which has not yet been achieved by any rational breakthrough.
The third point is the sound effect. Due to the lack of sound reflection sympathia compared to traditional in-ear headphones, and the ear canal remains open to allow the environment to enter a variety of sounds, resulting in the sound of the headset in both size and quality with other types of headphones. Blocking the ear can solve both problems to some extent, but both block the ear why not just buy an in-ear headset.
That said, bone-conductive headphones have and have only one advantage: it keeps your ear canal open while you're receiving a sound. However, it is useful in many cases, as exesthising:
1. Outdoor sports such as running and mountaineering. Of course, ordinary headphones can also solve the need to listen to music (sound quality is also better), but because of the characteristics of bone conduction headphones, listening to the song can also listen to the ambient sound, in the running can hear such as bicycle / electric car whistle, passers-by or peer safety reminders, so that the movement is relatively safer.
2. Driving, this is very understanding, when on the phone can also hear the outside sound, naturally safer.
