Hearing aids, though small and compact, are securely positioned in the ears when worn correctly, minimizing the risk of falling out. To maintain optimal performance, it is advisable to replace the domes every 2 to 3 months, as old domes may lose their shape and effectiveness, making them more prone to popping out of the ear canal. Exercise caution when combing your hair, removing glasses, and changing your shirt to avoid unintended displacement.
