Why does the hearing aid have loud screeching sound ? How to solve?

• Because the contact part of the earplug and the ear canal is not completely closed, the sound amplified by the hearing aid leaks from the gap and is amplified again by the microphone, so there will be a howling sound.

Solution:

1. Turn the volume to minimum first, then turn on the switch after wearing it well.
2. Choose suitable earplugs to keep the ear canal sealed.

How long can I wear it every day?

• People who have never used hearing aids, It is recommended to control it to 1-3 hours a day for the first week of wearing it, and extend it to about 5 hours a day after a period of use, depending on your own situation.
