At present, most of the wireless hearing aids on the market cannot avoid this phenomenon.Solution to whistling/noise:1. It is easier to howl when the amplified sound is loud, so turn off the hearing aid before trying it on, put the hearing aid in your ear after reducing the volume, start the hearing aid, and then adjust the volume2. When the ear canal is completely closed, there will be no howling. Before wearing, test the size of the earplug to ensure that the earplug and the ear canal are fully fitted without gaps.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, then release it to fully extend the earphone.4. Do not use the hearing aid for a long time when you use it for the first time, or you will have headache and dizziness. It is recommended that the first day of use should not exceed 4 hours, and the daily use time should be gradually increased to adapt
