The Hörluchs® HA UNLIMITED was specially developed for challenging noisy work environments. The linear filters ensure that warning signals can be heard exceptionally well and that speech can be understood in working noise. They are exchangeable so that the individual hearing protection can be specifically adapted to different noise environments (industry, crafts, forestry and agriculture). Its design ensures a perfect fit even when working overhead. The material is biocompatible, skin-friendly and silicone-free.


Taking impressions

In the first step, an impression of your auditory canal is made. With the scan of the impression, the hearing protection can be produced perfectly fitted.

3D production

Thanks to the state-of-the-art 3D production of Hörluchs®, the hearing protection is manufactured quickly and precisely. Re-production and new production are possible at any time thanks to 24 months of data storage.


The finished hearing protection can be collected from your Hörluchs® partner. You will receive detailed instructions including a functional test.
