Tips for buyers:
The cause of howling/noise: To make a small size hearing aid, the internal amplifier and the microphone are close to each other. The sound is continuously received and extended, so it has a certain possibility of producing howling after power-on. At present, small hearing aids and high-power hearing aids on the market can hardly prevent howling, and only full-digital hearing aids can prevent howling.

Ways to avoid howling/noise:
1. When the power is high (the amplified sound is large), howling is more likely to occur. Therefore, gradually increasing the volume of layer can effectively prevent howling.
2. When the ear canal is completely closed, there is no howling sound. So, please use hearing aids after cleaning your ear canal, and test the ear tips from largest to smallest to find the most suitable ear tips.
3. After the hearing aid enters the ear canal, it is recommended to push the hearing aid with your fingers and hold it for 1-2 seconds, and then release it completely from the earplug.

In addition: If you don't know how to use it or there is a problem with your hearing aid, please don't rush to leave a negative review and contact us. Thank you.

Description

Hearing aids are small and lightweight, making you comfortable. This hearing aid is unisex designed and can be worn by both men and women.

Q&A:
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 to Care for Hearing Aids?
1. Dryness: Hearing aids are electronic products and are prone to moisture. Pay attention to waterproof, moisture-proof and dust-proof.
2. Cleaning: Wipe with a dry, soft cloth. Use a small brush to clean the earwax inside and around the sound hole of the hearing aid.
How long can I wear it every day?
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.
According to many customer tests, you will get used to it after 2-3 weeks
