Tips:
Ways to avoid whistling/noise:
1. When the power is large (the amplified sound is large), it is more likely to produce howling. Therefore, gradually increasing the bass volume can effectively prevent howling.
2. When the ear canal is completely closed, there is no whistling sound. So after cleaning the ear canal, put on the hearing aid, test the earplugs from large to small, find the most suitable earplugs, and ensure that there is no air leakage.
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, then release it to fully extend the earphone.
4. In the shutdown state insert the aids into the ear. Make sure that the earbud completely fills the ear. Then turn on the power button and slowly increase the volume to a suitable volume.
5. Users who have not heard the sound for a long time may cause hearing loss due to the long-term failure to hear the sound, resulting in the hearing aid still unable to hear the sound. Please persevere, continue to stimulate the growth of the hearing nerve, and you will hear after a while. If you are not sure whether your hearing aid is working properly, you can try the product on a person with normal hearing.
6. Please pay attention to cleaning the ear canal and keep the earplugs clean.
