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.

Therefore, please use hearing aids after cleaning your ear canal, and test the earplugs from large to small to find the most suitable earplugs，Appropriate airtight earplugs are recommended.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 match the earplugs to the ear canal.In addition:If you do not know how to use it or there is a problem with your hearing aid, please do not rush to leave a negative review and contact us.
