1. Behind-the-ear hearing aid
It resembles the curvature of a banana and lies behind ears. Generally its length is about 4-5 cm long. The receiver opening is connected with a sound guide hook made of a rigid plastic tube, which is hung at the root of the upper edge of the auricle. The sound can pass from this hook, then go through the soft plastic tube and ear plug, finally go into the conchae and ear canal entrance, which helps to achieve the effect of hearing aid. In some countries, this type of hearing aid develops fastest. Many manufacturers can provide 30-50 products of different specifications, which means the functions of this type of hearing aid are gradually increasing.

It can also be named pocket or pocket model hearing ear machine, which resembles a cigarette case and is hung in a small pocket or pocket at the chest. A wire connects the headset with the main engine, then after inserting the headset into the external auditory canal, the aid can be put into use.
