Key Features


Extensive research into earplug preferences revealed that some workers prefer a firm foam earplug. They gain a sense of security from feeling the earplug in their ear. And while they like knowing the earplug is there, workers want greater comfort. Independent tests reveal that FirmFit outperforms the leading classic-style earplug, providing workers with a more comfortable option.


Longer wear time comfort: More protection. Greater compliance.

Greater Protection: Effective NRR 30dB provides excellent protection in most medium-to-high noise environments.

Easy to Insert: Requires less pressure to roll down. Slow recovery rate gives you plenty of time to correctly insert in ear canal.

Easy to See: Distinct warning orange color makes compliance checks easy.

Softer: You can feel that FirmFit is softer when you hold it.

Less Pressure: FirmFit exerts less expansion pressure on the ear canal.

  1.  With clean hands, roll the entire earplug into narrowest possible crease-free cylinder.
  2. Reach over your head with a free hand, pull your ear up and back, and insert the earplug well inside your ear canal.
  3. Hold for 30 – 40 seconds, until the earplug fully expands in your ear canal. If properly fitted, the end of the earplugs should not be visible to someone looking at you from the front. 
  4. Proper Fit – If either or both earplugs do not seem to be fitted properly, remove the earplug and reinsert. 
  5. Removal – Gently twist earplug while slowly pulling in an outward motion for removal. 
  6. Acoustical Check – In a noisy environment, with earplugs inserted, cup your hands over your ears and release. Earplugs should block enough noise so that covering your ears with your hands should not result in a significant noise difference.
