Hearing aids should be chosen according to the individual listening needs, subjective preferences, age, dexterity, cosmetic concern, severity and nature of the hearing loss.Listening needs Premium and high-end hearing aid models are equipped with more sophisticated digital speech processing technologies. However, they are more costly than entry and mid-level models.Subjective preferences, age and dexterity Some hearing aid users may prefer their hearing aids to be as invisible as possible. There are now a wide range of BTEs to suit different degree of hearing loss. Custom-made (ITE/ITC/CIC/IIC) hearing aids may not be suitable for young infants, and people with problems like dexterity, earwax or ear drainage.Cosmetic concern A custom-made hearing aid is smaller in size and plugged into the ear canal.
