Honeywell 3301161 Howard Leight MAX Foam Earplugs Fitting Instructions
With clean hands, roll the entire earplug into narrowest possible crease-free cylinder.
Reach over your head with a free hand, pull your ear up and back, and insert the earplug well inside your ear canal.
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.
Proper Fit – If either or both earplugs do not seem to be fitted properly, remove the earplug and reinsert
Removal – Gently twist earplug while slowly pulling in an outward motion for removal.
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.
