The Howard Leight by Honeywell Firm Fit Earplugs are softer than other cylindrical PVC foam earplugs. The plug exerts less expansion pressure on the ear canal of the user. The FirmFit requires less pressure to roll down, and a slow recovery rate provides plenty of time to correctly insert in the ear canal. The orange "warning" color assures easy compliance checks.
