Anyone who is frequently exposed to water and wind over many years runs the risk of
ear canal constriction and the associated far-reaching problems. Simple earplugs also protect against this - but they also block out a lot of noise and voices. With "Sowei Surf", an impression of your ear is taken by your local acoustician and the protection is then customised. With a built-in membrane that keeps water out and sound in.
Optimum protection costs 165 euros.
