Box hearing aids are also called body-mounted or pocket hearing amplifier. The shape of the box is like a small radio. The microphone, amplifier and battery of the hearing aid are assembled in the box and a long wire connects the earphone to the earplug or a special ear mould. Usually in pockets or special pouches. This kind of hearing aid has a large volume and is suitable for the elderly and people with inconvenient finger movement. The microphone of the hearing aid is far away from the receiver (earphone), so it is not easy to produce sound feedback. Therefore, the maximum output limit of the hearing aid is small, the power can be very large, and multiple manual adjustment knobs can be placed. Its price is low, maintenance is convenient, use No. 5 or No. 7 batteries, can also use rechargeable batteries.

Pocket hearing amplifier can also be made into binaural hearing aids because of their large size and poor concealment. Hearing aids are made of ordinary transistor elements, which have high background noise. In addition, the pocket hearing amplifier themselves and the friction between wires and clothes make the sound more distorted and the quality of the sound reduced. At the same time, earphone wires are easy to damage and children are not safe to wear.
