H10P3E Helmet Attachment Earmuffs | NRR 29 dB | Hard Hat Compatible
Elite protection for the loudest jobsites. The 3M Peltor Optime 105 H10P3E is engineered for noise environments reaching up to 105 dBA. Utilizing a proprietary Twin-Cup design, these earmuffs feature two cups connected via a foam inner layer to significantly reduce structural resonance and provide maximum attenuation across both high and low frequencies.
Designed for seamless integration, the H10P3E features a universal cap-mount attachment that fits most standard slotted hard hats. The stainless steel construction ensures the arms resist bending and warping, maintaining a consistent, low-pressure seal for all-day comfort. With liquid/foam-filled cushions, these earmuffs provide a superior acoustic seal even for workers wearing safety glasses.
Key Features:
-
Double-Shell Technology: Maximum noise blocking for extreme environments like airports, heavy manufacturing, and demolition.
-
NRR 27dB Certified: High-level attenuation that meets CSA Class AL safety standards for rigorous workplace compliance.
-
Multi-Position Capability: Earcups tilt for a customized fit and can be flipped back into a "standby" position when not in use.
-
Durable Comfort: Soft, wide cushions reduce pressure around the ears, preventing "head-squeeze" during long 12-hour shifts.
FAQ for E-E-A-T
Q: Will these earmuffs fit any hard hat? A: They are designed for slotted hard hats. They fit most standard brands like 3M, MSA, and Bullard. However, they are generally not compatible with full-brim hard hats without specific adapters.
Q: How do these compare to the H10A model? A: The Optime 105 H10A is the Over-the-Head version. The H10P3E offers the exact same protection level but is specifically modified with mounting arms for helmet use.
Q: Are the ear cushions replaceable? A: Yes. To maintain the NRR 27dB rating and hygiene, 3M recommends replacing the cushions and foam inserts every 6 months using the HY54 Hygiene Kit.
