This hearing aid automatically turns on 8 seconds after being taken out of the charging case and placed in the ear, and automatically turns off and starts charging when returned to the case. It's a smart design. The green LED lights up while the hearing aid is charging, and the remaining charge of the charging case is clearly displayed with blue numbers. There's no need to press troublesome operation buttons, providing a simple and intuitive user experience. *Please be careful not to block the microphone hole when using (to prevent howling). Manual power ON/OFF is also possible by pressing and holding for 3 seconds. 【One-Touch Volume Adjustment, Amplification up to 35dB】 This hearing aid is designed for easy operation, even for the elderly. You can adjust the volume in 4 levels by simply pressing the volume adjustment button, and you can check the current volume level by the number of beeps. We recommend starting with the minimum volume.
