BN803 is a bone conduction hearing aid headphone , instead of using traditional speaker , it use bone conduction technology to transmit sound .
unlike traditional earphones transmit sound by air , BN803 doesn’t plug or cover users’ ears, It transmit sound by skull to help people with weak ear drum and poor hearing .
And of course people with good hearing also can wear BN803 , in that case, users could hear outside voice and earphone voice at the same time . while people nearby can’t hear your BN803 , but you can listen to them and listen to your BN803 at the same time . BN803 can be used when you are working , studying ,sporting ,or for hearing aid purpose .

NOTICE :
*The bone conduction earphone is very useful for people with weak ear drum , but hearing nerve is still good . This is a general condition for most elderly . but if your hearing nerve is damaged , this earphone can’t help , pls don’t buy . you can consult your doctor for advice in advance .
PS. if traditional hearing aid by air is helpful to you , the bone conduction earphone is useful for you too , in a healthy way .

*People with good hearing might feel the bone conduction earphone voice is low or noisy . it’s because usually people with good hearing would focus on the sound through his ear drum only , and ignore sound through skull , and even turn the bone conduction earphone volume to highest to try listen clearly . such doing is not correct , bone conduction earphone works in different way with traditional speakers . Pls let the user with poor hearing try by themselves ,the earphone is very helpful for them , they can listen the sound through skull clearly .

How Bone conduction earphone give you good hearing and protect your ears ?
1.Auditory nerve is the final hearing organ.
2.Ear drum receive sound wave and transmit to Auditory nerve .Most elderly’s ear drums are damaged , lead to bad hearing .
3.Ear ossicle is a soft bone enclosing Auditory nerve . Ear ossicle vibration also can transmit sound to Auditory nerve . (by bone conduction earphone )
Most elderly’s ear drums are damaged , lead to bad hearing .However Auditory nerve is the final hearing organ ,most elderly’s auditory nerve is still good .Auditory nerve is enclosed by Ear ossicle soft bone .
Bone conduction earphone transmit sound through ear ossicle instead of ear drum .it can
protect elderly’s ear drum ,and give elderly good hearing .
Traditional hearing aid earphone transmit sound by air through ear drum simply by enhancing sound wave ,It might lead to further damage to elderly’s ear durm .and elderly would get more and more annoyed and painful by wearing traditional hearing aid earphone .
Bone conduction earphone is an innovative and healthy hearing aid product for elderly .
7 bands sound frequency option function
803’s control box can recognize and adjust 7 frequency bands of sound .it’s very useful for some elderly , whose ears are sensitive to certain sound frequency , but insensitive to other frequency .
803 provide 7 frequency modes for elderly to choose most comfortable sound frequency for them . and separately adjust right /left voice volume too . healthy hearing for elderly !
What is real bone conduction ?
Bone conduction technology is to create vibration around user’s cheek to transmit sound to user’s hearing nerve through soft ear bone inside .It is a revolutionary hearing aid technology , and very suitable for users with poor hearing drum .
However because when creating vibration , it cause air wave at the same time —- it makes sound like traditional speakers at the same time . So some manufacturers use traditional air conduction speaker or use very tiny and weak “so called ” bone conduction component to pretend bone conduction earphone . Those so called tiny bone conduction earphones can’t make much vibration , actually still transmit sound by air like traditional speakers . So users can’t feel the advantage of bone conduction technology with those ” fake ” earphones .
We advice customers who want to enjoy bone conduction technology , choose those earphones with bigger and better bone conduction components .
More to love : cheaper BN802 model , without 7 frequency bands selection function
BN802 is cheaper , but its control box function is different with BN803’s . BN802 can not select frequency bands of sound, while BN803 allow user to select frequency bands (7 options ). However BN802 is still a wonderful bone conduction hearing aid earphone . Welcome to order !
