Light and comfortable hearing

The slim, off-the-ear sound processor is light and comfortable to wear.1 As an all-in-one unit, an adult or child simply places it on their head behind the ear, adjusts their hair and they are ready to go. There are no small pieces to bother with, and their ear is left open and free.


A choice of colours

The Osia System comes with five coloured covers for the sound processor, so an adult or child can change the colour based on their preference and mood.

The Osia System has just made life easier and the advantages are so worthwhile. It's changed my life so much for the better, and I'm really grateful for that.
