2 channel Rechargeable open fit waterproof hearing aids for moderate hearing loss
Directional microphone technology
This is also a strategy for better hearing in background noise.
Hearing aids that come with just one microphone function in an
omnidirectional mode (meaning sound is picked up from all around).
Hearing aids with directional microphone capabilities typically
have two microphones and have the ability to focus (or direct) one
microphone toward the sound source while the other attempts to
decrease some of the background noise.
Small size and BTE with high sound quality; Right and left ear
for different side ear;With cleaning tool and volume control bar;
Cheap price and hot selling.

How can hearing aids help?
Hearing aids are primarily useful in improving the hearing and speech comprehension of people who have hearing loss that results from damage to the small sensory cells in the inner ear, called hair cells. This type of hearing loss is called sensorineural hearing loss. The damage can occur as a result of disease, aging, or injury from noise or certain medicines.
A hearing aid magnifies sound vibrations entering the ear. Surviving hair cells detect the larger vibrations and convert them into neural signals that are passed along to the brain. The greater the damage to a person’s hair cells, the more severe the hearing loss, and the greater the hearing aid amplification needed to make up the difference. However, there are practical limits to the amount of amplification a hearing aid can provide. In addition, if the inner ear is too damaged, even large vibrations will not be converted into neural signals. In this situation, a hearing aid would be ineffective.
