Choose slightly larger earplugs to avoid whistling. Insert the hearing aid into the ear canal and adjust its position in the ear canal until the soft ear tip fully unfolds and fills the ear canal;. If you hear a whistle, check whether the ear (silicone) is suitable, whether the size of the plug is tight.
