The foundation of occupational workplace safety starts with absolute compliance and premium acoustic barrier protection. Wellmien’s high-visibility orange safety earplugs feature an advanced bell-shaped ergonomic contour, providing custom-fit comfort and high-decibel noise reduction for long industrial factory shifts.
Ergonomic Anti-Backout Shape: Engineered with a flared bell base that mirrors the natural anatomy of the outer ear canal, effectively preventing the plug from backing out or shifting during intense physical labor.
Premium Slow-Recovery Matrix: Crafted from top-tier polyurethane (PU) foam with a slow recovery time of 25–45 seconds, allowing operators ample time for perfect depth insertion and cross-contamination prevention.
Soil-Resistant Smooth Skin: The non-porous, smooth exterior resists the accumulation of workplace dust, grease, and sweat, helping maintain strict hygiene before entering the ear canal.
Standard PU foam industrial safety earplugs with 29–33 dB NRR rating. Optimized for heavy manufacturing, assembly lines, and high-volume corporate PPE procurement.

A: Our standard PU foam earplugs are calibrated with a controlled recovery time of 25–45 seconds. This gives safety officers and factory workers sufficient time to roll down the foam, guide it into the ear canal, and hold it until it expands fully to form an airtight seal.
A: Yes. While high-visibility orange, yellow, green, and blue are standard, our factory supports full OEM custom coloration. The MOQ for custom colors is 50,000 pairs, and we can provide sample matching within 5 working days.
