China Digital Programmable Spieth BTE021 BTE Hearing Aids
Behind-the-ear (BTE) hearing aids consist of a hard plastic case worn behind the ear and connected to a plastic earmold that fits inside the outer ear. The electronic parts are held in the case behind the ear. Sound travels from the hearing aid through the earmold and into the ear.
Acrylic is typically considered the standby material for earmolds. The hard material is legacy, with a long of enough history for hearing healthcare professionals to acknowledge that the majority of BTE hearing aid wearers have earmolds made of acrylic.
This type of BTE hearing aid with its new design and high technology has directional microphone function can bring new experience and better hearing.
