How to Insert the Core One Pro correctly

A correct fit is one of the biggest factors in comfort and sound quality.

How to insert it

  1. Identify the left and right hearing aids by the blue and red markings.
  2. Hold the hearing aid with two fingers, with the thread pointing down.
  3. Gently insert it into your ear canal.
  4. Make sure the eartip sits securely and comfortably.

Good to know

If the hearing aid feels loose, whistles, or feels uncomfortable, try a different eartip size.
