Made with Love in Berlin: earplugs

Who invented them?
Maximilian Negwer

What are they?
Noise protection

How do they work?
The original Ohropax earplugs were wax noise protection for human ears. The first Ohropax earplugs were sold in a tin box containing six pairs of balls of wax. Today, there are also foam, silicone and plastic models on the market. Incidentally, the term Ohropax is a combination of the words "Ohr" (German for ear) and "Pax" (Latin for peace).
