The COMZ®-35 ABSOLUTE (article 63501) is a passive noise-canceling headset manufactured by ROSOMZ — the Sukhumsky Optical-Mechanical Plant, a long-established Russian producer of certified personal protective equipment. Achieving an SNR of 30 dB, these earmuffs are engineered for selective noise absorption: they attenuate hazardous noise up to 110 dB while preserving the wearer's ability to hear speech and audible safety signals — a decisive advantage in dynamic industrial workplaces.
The cups are injection-molded from durable ABS plastic resistant to elevated temperatures and UV radiation, filled with specially formulated open-cell polyurethane foam that delivers effective broadband attenuation. The sealing cushions are produced from a multi-layer hypoallergenic thermoplastic elastomer that stays comfortable against skin during long shifts.
Cup holders slide independently along the steel headband to fit head sizes M and L, maintaining consistent acoustic seal geometry across different head shapes. Tipping the scales at no more than 190 g, the COMZ®-35 ABSOLUTE claims the highest noise-reduction figure relative to its cup dimensions in the ROSOMZ lineup.
The design is fully compatible with ROSOMZ protective helmets and balaclavas, making it easy to build compliant, multi-layer PPE combinations without clearance issues.
