Rechargeable Mini Digital Hearing s The Listening Device Wireless Sound Amplifier Adjustable Deaf Elderly Hearing

Ts for buyers:

Causes of whistling/noise: In order to make a small hearing , the internal amplifier and microphone are placed close to each other. The sound is continuously received and expanded, so there is a certain poibility of whistling after power-on. At present, small hearing s and high-power hearing s on the market are difficult to avoid whistling, and only fully functional digital hearing s can avoid whistling.

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 ba volume can effectively prevent howling. 2. When the ear c is completely closed, there is no whistling sound. So after cleaning the ear c, put on the hearing , test the earplugs from large to small, find the most suitable earplugs, and ensure that there is no air leakage. 3. After the hearing enters the ear c, it is recommended to push the hearing with your fingers and hold it for 1-2 seconds, then release it to fully extend the earphone. 4. In the shutdown state,turn the volume of the hearing to the lowest level, then insert it into the ear. Make sure that the earbud completely fills the ear. Then turn on the power on and slowly increase the volume to a suitable volume. 5. Users who have not heard the sound for a long time may cause hearing lo due to the long-term fai to hear the sound, resulting in the hearing 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 is working properly, you can try the product on a person with normal hearing. 6. Please pay attention to cleaning the ear c and keep the earplugs clean.
