1, wearing problems, because of its design characteristics, so in the noisy environment such as shopping, taking the subway, taking a car, the product effect is not ideal.

2, the sound quality problem, some frequency bands are disabled, and the sound field effect is not good, because the technology of the current product is still immature, and the air feeling of the sound is not easy to satisfy.

3. Sound leakage still needs to be overcome. If there is a common problem with bone conduction headphones, it is the problem of sound leakage. Although major manufacturers are trying to improve the sound leakage of bone conduction headphones, according to the actual situation of bone conduction headphones, there is still sound leakage in bone conduction headphones.

Extended data:

Bone conduction is a way of sound transmission, that is, sound is transformed into mechanical vibration with different frequencies, and sound waves are transmitted through human skull, bone labyrinth, lymphatic transmission of inner ear, spiral organ, auditory nerve and auditory pathway. Compared with the classical sound transmission method which generates sound waves through the diaphragm, bone conduction saves many steps of sound wave propagation, and can realize clear sound reproduction in noisy environment, and sound waves will not affect others when they propagate in the air.

Bone conduction technology is divided into bone conduction speaker technology and bone conduction microphone technology.

Earphones with bone conduction speaker technology: When wearing and using, the ears are open and will not be blocked, which solves the uncomfortable feeling of wearing in-ear headphones. At the same time, it also avoids a series of health problems caused by ear sweating when wearing headphones. Therefore, bone conduction speaker headphones are very suitable for sports use. Opening ears also ensures the possibility of using headphones in dangerous scenes. When you open your ears, you can also notice the changes in the surrounding environment while using headphones, which is safer to use.

Headphones with bone conduction microphone technology: Due to short sound collection distance, low loss. Even when the voice volume is very low, the other party can clearly know the instructions expressed, which is mainly used in the military field.
