Elvex EP-411 Quattro Corded Earplugs — NRR 25 lysian What is the difference betweenEDITORIAL REVIEW: 3. 8 5WC Safety Review Elvex EP 411 Quattro Corded Earplugs Best For: corded reusable flanged hearing protection at NRR 25 dB with a retention cord. Not For: non noise hazards, or noise that earplugs alone can't bring under ~85 dBA (add earmuffs). Bottom Line: a solid corded reusable flanged plug at NRR 25 dB the cord earns its keep on jobs where dropped plugs get lost. Editorial assessment by Steven Eaton, WC Safety editor. Scoring
