BTE hearing aids
BTE hearing aid refers to a hearing aid that hangs behind the ear. It consists of an ear body, an ear hook, an ear tube, and an earplug. It is suitable for patients with various types of hearing loss and can achieve many unexpected functions. The multi-functional receiver provides more power options and the hearing aids come in a variety of colors. Some colors can basically be made invisible after being worn, thus improving the aesthetics.

Causes of hiss/noise: To make a small hearing aid, the internal amplifier and microphone are placed close to each other. The sound is continuously received and expanded, so there is some possibility of hiss after turning it on. At present, the small hearing aids and high-power hearing aids on the market are difficult to prevent whistling, and only fully functional digital hearing aids can prevent whistling.
Ways to avoid hissing/Noise:
1. When the power is large (the amplified sound is large), it is more likely to produce howling. Therefore, gradually increasing the bass volume can effectively prevent howling.
2. When the ear canal is completely closed, there is no whistling sound. So after cleaning the ear canal, put on the hearing aid, try the earplugs from big to small, find the most suitable earplugs, and make sure there is no air leakage.
3. After the eartip enters the ear canal, it is recommended to push the eartip in with your fingers and hold it for 1-2 seconds, then release it to fully extend the eartip.
4. In the state of power off, please turn the earphone volume to the lowest level, and then insert into the ear. Make sure the earpiece completely fills your ear. Then turn on the power button and slowly increase the volume to a suitable volume.
5 users who have not heard the sound for a long time may cause hearing loss due to long-term failure to hear the sound, making the hearing aid still unable to hear the sound. Please toughen up, continue to stimulate the growth of the auditory nerve, and you will hear after a while. If you are not sure if your hearing aid is working properly, you can try the product on a person with normal hearing.
6. Pay attention to the cleanliness of the ear canal and keep the earplugs clean.
