FAQ
What does the metal-detectable variant (EC-1001A-C-D) add?
The -C-D corded variant is intended for food processing or pharmaceutical production lines where earplug fragments must be detectable by metal detectors if accidentally dropped into product. Confirm your line's detector sensitivity requirements at quote stage.
Is this the highest-NRR model in the PU foam range?
Among the standard disposable PU foam models with published test data, EC-1001A has the highest SNR (38dB) in this category. If your noise environment needs maximum attenuation, start here.
Can I get a corded version if it's shown as uncorded, or vice versa?
Yes, corded and uncorded are both standard offerings for this model — confirm which you need at quote stage.
