Tips for buyers:
The cause of crying/noise: for a small size hearing aid, the internal amplifier and the microphone are close together. The sound has been continuously received and expanded, so it has a certain possibility of producing crying after power-on. At the moment, small hearing aids and high-power hearing aids on the market can hardly occur crying, and only full-digital hearing aids can prevent crying.
Ways to prevent crying/noise:
1. When power is high (the reinforced sound is large), crying is more likely to occur. That is why gradually increasing the volume of low can effectively prevent crying.
2. When the ear canal is completely closed, there is no crying sound. So, use hearing aids after cleaning your ear canal, and test the earplugs from large to small to the most suitable earbuds.
3. After the hearing aid comes in the ear canal, it is recommended to push the hearing aid with your fingers and keep it for 1-2 seconds, and then release it completely out of the earplug.
Moreover: if you do not know how to use it if there is a problem with your hearing aid, please do not rush to a negative assessment and contact us. Thank you.
