The Pros and Cons of IIC Hearing Aids

June 2023.

IIC (invisible-in-canal) hearing aids are the smallest type of hearing aid available, as they sit completely inside the ear canal and are virtually invisible. Like all hearing aids, IIC hearing aids have advantages and disadvantages.


  • Virtually invisible: IIC hearing aids are the most discreet hearing aids available, as they sit completely inside the ear canal and are almost invisible.

  • Comfortable: IIC hearing aids are designed to be comfortable to wear, with a custom fit that conforms to the shape of the wearer's ear canal.

  • Good sound quality: IIC hearing aids provide excellent sound quality, as they are located close to the eardrum.

  • Minimal wind noise: IIC hearing aids are located inside the ear canal, which can minimize wind noise and other external noises.

  • Can be worn during physical activities: IIC hearing aids are suitable for physical activities, as they are less likely to fall out or get in the way during exercise or sports.


  • Limited battery life: IIC hearing aids use small batteries that need to be changed frequently, which can be inconvenient and expensive for some people.

  • Vulnerable to moisture and earwax: IIC hearing aids are susceptible to moisture and earwax build-up, which can damage the electronic components inside and require frequent cleaning.

  • Not suitable for severe hearing loss: IIC hearing aids may not provide enough amplification for people with severe hearing loss.

  • May cause occlusion: IIC hearing aids can cause a sensation of occlusion, or the feeling of being "plugged up," due to their location in the ear canal.

  • Limited features: IIC hearing aids may have limited features compared to other types of hearing aids, such as directional microphones or wireless connectivity options.

  • Difficult to handle: IIC hearing aids can be difficult to handle, as they are small and located deep inside the ear canal.

    Overall, IIC hearing aids are a good option for people who want the most discreet hearing aid available, with excellent sound quality. They are suitable for mild to moderate hearing loss and can be worn during physical activities. However, they may not be the best choice for people with severe hearing loss or those who are concerned about moisture or earwax build-up. It's important to consult with a hearing care professional to determine if an IIC hearing aid is the best option for an individual's specific hearing needs and lifestyle.
