It is beautiful and concealed and is not easily found by others. The behind-the-ear hearing aid uses a small plastic tube to transmit the amplified sound into the mouthpiece of the eardrum. There are small, medium and large files to adjust the output power, which is convenient for people with different hearing loss. The current design of the ear-back machine is very fashionable and has become a new choice for most patients with deafness.

It can make full use of the sound collection function of the outer ear. The concealment is very good and it is not easy to be discovered. Answer the call like a normal person. The in-ear hearing aid is customized according to the shape of the ear canal. It is comfortable to wear and has the function of moisture-proof and sweat-proof.

Product output power
1. The ear-back hearing aid can contain more additional functions of the hearing aid, such as FM, Bluetooth, etc., because of its large size, which meets the different needs of many people. At the same time, there are some better ear-back hearing aids that can display natural directionality. At the same time, due to the appearance setting, dual microphones can be set to activate different directionality, which can ensure speech signals in complex environments, ensuring clarity and intelligibility.
2. The in-ear hearing aid has a very powerful chip processing capability and a large power range, which largely satisfies a large part of patients' needs for appearance and sound. However, the in-ear hearing aid does not fall and cannot be damp. At the same time, it is necessary to prevent the sputum from clogging the horn to ensure a small failure rate of the in-the-ear hearing aid.
The output power of the in-ear hearing aid is not very high. It is only suitable for patients with mild, moderate or moderate to severe deafness. The ear can only achieve high power, and the ear type rarely achieves high power. Therefore, when the hearing loss is extremely severe, the behind-the-ear type is preferred.
There are some obvious defects in the behind-the-ear hearing aids. Because the behind-the-ear hearing aids are placed behind the ear, they are easily eroded by the sweat flowing down the head, which in turn damages the components. In addition, when the behind-the-ear hearing aid is used, the knob adjustment is difficult, and it is not suitable for children or elderly people whose finger movement is not coordinated. In the case of the same function of hearing aids, the price of the behind-the-ear hearing aid is much cheaper; but due to the size of the appearance, there is no Bluetooth, FM and other functions in the ear. How to choose specifically, it also needs to be determined by professional audiologists according to the actual situation of users.
