Jrenum® custom hearing protection

High wearer comfort thanks to custom production

Are you exposed to noise? Do you have to protect yourself and hear in spite of that? Do you need hearing protection all day long? Does your current hearing protection pinch? Do you hate that closed-in feeling? Do you wear glasses and the hearing protection gets in the way? Do you constantly have to speak with people and remove the hearing protection?

The solution: anatomically matched protection for your ear

How does this work? We take a silicone impression of your ear canal and use this to make your personal, custom JRENUM® hearing protection.

JRENUM® hearing protection can be worn comfortably all day long. Two ear pieces designed to fit you perfectly are made in our laboratory for every wearer based on the precise impression of the outer shape of the ear. They do not cause any pressure marks and form an optimum seal. A filter unit makes the necessary pressure compensation possible. This therefore guarantees high speech comprehension even when there is lots of environmental noise.

We demonstrate the hearing protection for you on site and issue you a quotation tailored to you needs. At the same time, we show you the different test options for your service.

  • Can be worn all day long
  • High wearer comfort
  • No excess pressure
