Description
1. It is easier to scream when the power is high (the amplified sound is loud).
Therefore, gradually increasing the low volume can effectively avoid screaming.
2. There is no screeching when the ear canal is completely sealed.
Therefore, please use the hearing aid after cleaning the ear canal, and test the earplugs from large to small to find the most suitable one.
3. After the hearing aid enters the ear canal, it is recommended to push the hearing aid with your finger and keep it for 1-2 seconds, then release it so that the ear plug is fully extended.
