The SonoCustom is a 'world first' in instant fitted custom calibrated hearing protection.
No two ears are the same so it's no wonder 'one size fits all' hearing protection is uncomfortable for most people.
The SonoCustom is formed directly is the ear by a unique 'inflation' technique. It is an entirely comfortable and simple process.
The person being fitted provides instant feedback on comfort.
No ear impressions are required. |
