Most hearing aids stop working due to earwax blockage, battery or charging failure, moisture exposure, incorrect settings, or poor fit. In most cases, the issue can be fixed without replacing the device.
Hearing aids are sophisticated digital devices, but daily use exposes them to conditions that can affect performance. Understanding why hearing aids stop working helps users respond quickly and avoid unnecessary repairs.
