How to wear:
1.Adjust volume to the minimum before wearing.
2.Choose an earplug of slightly bigger size to avoid whistler.
3.Increase volume gradually to avoid sudden increase in sound.
4.If you hear a howling, check the ear (silica gel) is appropriate and whether the size of plug is tight, the appropriate choice of earplugs and plugged, make sure no air leakage. If it still does not work, please check the chat window leave me a message.
5.Keep the ear plug clean.
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，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.
