my mum just got the widex too...RM4k x 2. Good clarity and minus the hissing sound. Can adjust like high range amplifier.

But it is $$$ pricey.

Pay a visit to Mid Valley / BP Pathlab / Hearing Solution.

First they will place the patient in a confine room wearing headphone. Then listen to sound and press a button. If the sound is too soft, and you don't press the button, the doctor will know then. After obtaining the result, it will tell you which side of ear is having and how bad is it.

Budget at least RM2k for a decent one. If budget limited, get 1 side...it's ok. My family are very happy when it help my mum can listen clearly again. We don't need to shout.
