Hearing protection headphones 3M 7000039616

3M™ PELTOR™ Optime™ I Earmuffs (model H510A) are lightweight hearing protectors designed to reduce noise levels by up to 28 dB. With a low-profile shape and soft, wide cushions, these earmuffs are intended for comfortable, long-duration use and can be combined with other safety equipment. They are suitable for moderate industrial noise and outdoor tasks such as lawn mowing and hedge trimming. The cushions and foam inserts are replaceable via Hygiene Kits, and the product is available in folding headband, neckband, helmet-attached and Hi‑Viz green variants.

Advantages

The 3M 7000039616 hearing protection headphones offer effective attenuation up to 28 dB while remaining lightweight and easy to wear. Their low-profile design allows use together with other personal protective equipment. Wide, soft sealing rings with a liquid-and-foam filling reduce pressure around the ears and provide a comfortable seal; the cup interior is large enough to limit heat and moisture build-up. Replaceable cushions and foam inserts extend product life.

Suitable for

• Moderate industrial noise (workshops, sheet-metal shops, printing works)
• Outdoor maintenance (lawn mowing, hedge trimming)
• Agricultural work and other noisy field tasks
• Use with helmets or other safety equipment (helmet-attached or headband variants)

How to use

Place the headband over the head (or attach the earmuffs to a compatible helmet or neckband variant) and position the earcups to fully enclose the ears.

For comfort during extended use, ensure the cushions sit evenly and avoid over-tightening. Replace cushions or foam inserts when worn or damaged following the Hygiene Kit instructions.

Usage recommendations

Use these earmuffs for tasks with moderate noise levels and where compatibility with other PPE is required. Measure on-site noise levels if unsure about required protection; combine with other hearing protection measures if noise exceeds recommended exposure limits.
