Tips for buyers:

The cause of howling/noise: To make a mini-size hearing aid, the internal amplifier and the microphone are close to each other. The sound is continuously received and expanded, 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 avoid howling, and only full-digital hearing aids can avoid 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 from low can effectively avoid howling.

2. When the ear canal is completely sealed, there is no howling sound. Therefore, please use hearing aids after cleaning your ear canal, and test the earplugs from large to small to find the most suitable earplugs.

3. After the hearing aid enters the ear canal, it is recommended to push the hearing aid with your fingers hold it for 1-2 seconds, and then release it to fully extend the earplug.

Feature

1. Peak Gain(dB): 35dB, Suitable for mild to moderate hearing loss (Reference hearing loss map)

2. Biomimetic design: Designed for hearing impaired, more fitting ear canal. Do not feel pain even when worn for a long time.

3. Intelligent chip sound amplification: Distinguish speech even in noisy environments.

4. Long working time: One A10 battery can last about 60 hours.Convenient and practical.

5. If the ear dome is not filled into the ear canal or air leaks at the ear dome, it will cause an annoying whistle. We give 3 different sizes of earplugs to reduce howling and noise.
