A secure fit helps your Core One sound better and reduces whistling.
- Identify the left and right hearing aids before inserting them.
- Hold the hearing aid so the ear tip points into your ear canal.
- Insert it slowly until it feels secure and comfortable.
- Adjust the position so it sits snugly without pressure or pain.
- For models with a pull thread, leave the thread pointing downward so you can remove the device easily.
What to expect
- If the hearing aid feels loose or whistles, try a different ear-tip size.
- If it feels painful, do not force it deeper—remove it and try again.
