Tips for buyers:

Whistling may occur if the hearing instrument is turned on,but not securely seated in your ear.this is normal.the whistling will stop once the device is properly seated in your ear.other caused include a blockage of wax.or damaged ear piece or tubing,or excessive volume.Please take appropriate measures to stop the whistling.

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.

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 then release it to fully extend the earplug.

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. Thank you!
