Product highlights

Hellberg Secure 1C earmuffs are designed for professional use in environments where simultaneous head and hearing protection is required. The durable spring-steel attachment system withstands more than 10,000 movement cycles, corresponding to at least five years of normal use.

The three-position system allows the earmuffs to be placed in working position, standby mode, or parked behind the helmet when not in use. The non-conductive construction without exposed metal parts increases user safety.

Soft replaceable sealing rings reduce perspiration and ensure comfortable wear even during prolonged use. The snap-in system enables hygienic and quick maintenance.
