What model is right for you?

Hearing loss is not a “one-size fits all” condition. For this reason, there are many different models and styles of hearing devices. Which hearing aid best suits a wearer’s needs comes down several factors, including:

  • The severity of the hearing loss
  • Lifestyle
  • The user’s dexterity
  • Budget considerations
  • Aesthetics

Hearing aids can essentially be placed in three categories.

  • Invisible in the Canal (IIC)
    – Custom in-the-ear models (CIC, ITC, ITE)
  • Behind-the-ear (BTE)
  • Receiver-in-canal (RIC)

In-the-ear models

In-the-ear models are custom-fitted to the contours of your ear canal. They include:

  • Completely in the Canal (CIC)
  • In the Canal (ITC)
  • In the Ear (ITE)

Different models are more or less invisible in your ear. The size and shape of your ear canal along and the severity of your hearing loss will determine which model of custom hearing aid is right for you.

Suitable for: mild to moderately-severe hearing loss.

Behind-the-Ear models (BTE)

The main section (case) is hidden behind the ear is connected to a thin clear tube that passes into the ear canal.

Your audiologist will help you determine whether you prefer a fully-automatic aid that requires no manual adjustments or a hearing aid that offers more manual control.

These hearing aids are very discreet and come with multiple program options. Smartphone applications allows you manage your hearing aid settings via your phone.

Suitable for: all types of hearing loss


Receiver-in-the-Canal (RIC), hearing aids combine the advantages of the behind-the-ear and custom (in-the-ear)

The microphone is at the end of the tube inside the ear canal and is connected to the main body of the hearing aid by a thin transparent tube. By placing the receiver inside the ear, cases that sit behind the ear can be smaller. The result is a virtually invisible hearing instrument that offers open-fit comfort and optimal suppression of wind noise.

Suitable for: mild to moderately severe hearing loss
