Concerts, festivals, open airs and clubs are like your living room. You love music at every second: clear, honest and direct. Every nuance, every detail in the song is something special for you. That’s exactly why we have developed this hearing protection:

The SOWEI UNLIMITED is the ideal hearing protection for music lovers. Precise customisation and special filter technology allow you to enjoy your music just as it is. Clear and unadulterated sound experience from the sub-basses to the highs. This is made possible by the special Hörluchs HLM filters with linear dampening over the entire frequency range. You can understand speech perfectly while your hearing is protected.

This hearing protection is made to fit exactly according to the impression of your ears. The SOWEI UNLIMITED is made of 100% 3D soft silicone. It fits perfectly in every situation – no matter if you are dancing in the crowd or giving 100% with your band on stage.

Since all filters (except HLM10) in combination with the earmould have a type examination certificate, the SOWEI UNLIMITED can also be used in loud workplaces where a lot of communication is required. Optionally, this hearing protector can also be manufactured with a handle and a carrying strap.

Linearity over the
entire frequency range

Depending on your taste, you can choose one of 5 linear HLM filters – exactly as to your needs. The filters can be changed at any time. They are robust, easy to swap and durable.

Unlike similar filters from other manufacturers, you can clean them easily with water and mild soap. This means they do not have a fixed replacement interval.
