Professional Hearing Protection: Calibrated to deliver an exceptional Signal Noise Ratio (SNR) of 32 dB and a Noise Reduction Rating (NRR) of 26 dB to isolate ears from extreme decibel hazards.
100% New TPE Conical Design: Precision-molded from premium, brand-new Thermoplastic Elastomer (TPE) material that retains its elastic structural memory and shape through prolonged washing and wearing cycles.
Advanced 3-Layer Acoustic Seal: Engineered with a specialized triple-tier flange layout that conforms securely smoothly to the inner ear canal walls, maximizing noise blockade while minimizing insertion pressure.
Humidity & Sweat Resistant Shielding: Highly resistant to moisture buildup and perspiration tracks, actively preventing damp air and water accumulation inside the inner canal during strenuous work environments.
Certified Multi-PPE Compatibility: Fully certified to conform to international EN 352-2:2020 and ANSI 3.19-1974 standards, with a slim profile designed to fit cleanly beneath industrial earmuffs.
