Product details
Ts for buyers:
The cause of howling/noise: The internal amplifier and microphone of the hearing are very close, and the sound is continuously received and expanded, so there is a certain poibility of howling after turning on. The small hearing s and high-power hearing s currently on the market can hardly avoid howling, and only all-digital hearing s can avoid howling.
Ways to avoid howling/noise:
1. When the power is high (the amplified sound is loud), howling is more likely to occur. Therefore, gradually increasing from a low volume can effectively avoid howling.
2. When the ear c is completely sealed, there is no whistling sound. Therefore, please use hearing s after cleaning the ear c, and test the earplugs from large to small to find the most suitable earplug.
3. After the hearing enters the ear c, it is recommended to push the hearing with your fingers and hold it down for 1-2 seconds, and then release it so that the earplugs are fully extended.
In addition: If you don’t know how to use it or your hearing has a problem, please don’t rush to leave a bad review and contact us. thank you.
