There are many types of headphones, but hardly anyone knows about headphones that have bone conduction. Bone conduction is when sound is not perceived by the hearing aid, i.e. ear, and the bones of the skull, to be more precise - zygomatic.
Content
To make it more clear, you first need to remember how a hearing aid works in general. The ear is divided into 3 sections: external, middle and internal, and receptors.The eardrum is located in the outer ear, which transmits vibrations to the inner ear, which, in turn, converts the vibrations into signals, after which they go straight to the brain. The inner ear has an interesting feature, not only is it able to convert vibrations into signals, it can also modify the vibrations that come from special headphones into sound signals. At the same time, sounds familiar to a person do not come from them, they are radically different from the usual ones.
Most people think that the ear is tuned to pick up the vibration that the gas/air creates. But this is not entirely correct, because the inner ear is attached directly to the skull of the head, and these two parts work together. The bones of the skull receive vibrations, send them to the inner ear, and it converts the vibration into sound. Perception by the skull and ear is different. The skull perceives low-frequency vibrations well, but high-frequency vibrations are poorly perceived. The ear, on the contrary, captures high frequencies well, and low frequencies poorly. Due to the peculiarities of perception, people always think that their voices are several frequencies lower than they really are.
There are cases when, for some reason, the eardrum ceases to function in people. In such cases, you should wear headphones with a base on bone conduction. Because vibrations are perceived by the bones of the skull, the eardrum is not needed to modify the vibrations. Due to bone perception, a person can hear everything around him and without an eardrum.
Since the beginning of mass production of this product, not enough time has passed to test them for effectiveness. Experiments were carried out and they were successful. They began to be sold to the military, doctors and ordinary people.
The most popular model in the world. The headphones fit perfectly, do not press anywhere, are quite light, almost not felt.

When worn, nothing presses, the weight is felt, but just a little bit. In general, bone conduction headphones are not very good at transmitting high vibrations, but these excel. Customers said that high-frequency sounds are heard well, and low-frequency sounds are perfect. Unfortunately, there are several downsides. The first is the wiring, if it is broken, then it will be easier to buy new ones if you do not want to spend an impressive amount on changing several wiring.

There is a microphone for communication, but because he is only one, it will be a little difficult to hear his interlocutor, although if you communicate through a computer, there will be no problems.The sounds are not quite high-quality, there are few high-frequency and low-frequency sounds, in noisy places the music is hard to hear. As for the materials, the temple is covered with a glossy finish, which is inconvenient, because. all contamination is visible. The size of the temples is adjustable. There were cases when, instead of vibrations, some cods were heard, subsequently the buyers began to have a headache, but these were isolated cases.

In the past, when this product first appeared on store shelves, it had a completely different look, looked bulky and weighed a lot, so it was impossible to wear them for a long time. At the moment, the brand has improved this model, it began to look aesthetically pleasing, the weight has almost halved. It was a pleasure to wear them.
