FAQ
How is this different from EC-1001A?
Both are high-attenuation bullet designs with similar NRR (32dB), but EC-1003A uses a longer tapered profile aimed at deeper ear-canal insertion for industrial settings, while EC-1001A uses a shorter bullet profile. SNR differs slightly (37dB vs. 38dB) — request both frequency tables if you need to compare precisely for your noise profile.
Is the metal-detectable version the same price as standard?
Metal-detectable and corded variants typically carry a different unit cost than the base uncorded model. Confirm pricing per variant at quote stage.
