H10P3E Helmet Attachment Earmuffs | NRR 27 dB | Hard Hat Compatible
The 3M PELTOR Optime 105 H10P3E Cap-Mount Earmuffs are high-attenuation hearing protection earmuffs designed for workers who need hard hat-mounted noise reduction in construction, manufacturing, demolition, mining, oil and gas, transportation, metal fabrication, and facility maintenance environments.
With an NRR of 27 dB, the H10P3E helps reduce workplace noise exposure when properly fitted and used as part of a hearing conservation program. The cap-mount design attaches to compatible slotted hard hats, helping workers combine head protection and hearing protection without switching to separate headband earmuffs.
The Optime 105 series uses 3M PELTOR Twin-Cup technology to help reduce resonance and improve noise-blocking performance across low and high frequencies. Soft foam-filled cushions support worker comfort during long shifts, while stainless steel construction helps resist bending and warping in demanding work environments.

Safety Note
NRR is a laboratory rating and may not equal real-world workplace attenuation. Proper fit, hard hat compatibility, cushion condition, worker training, and correct use all affect hearing protection performance. Select hearing protection based on workplace noise monitoring, OSHA hearing conservation requirements, and your safety manager or EHS program.

Buying Guide: Cap-Mount vs. Over-the-Head Earmuffs
Choose the H10P3E cap-mount version when workers must wear hard hats and hearing protection at the same time. It helps reduce PPE conflict and keeps hearing protection attached to the helmet.
Choose the H10A over-the-head version when workers do not need a hard hat or when helmet mounting is not compatible with the jobsite head protection.
