Reusable ear plug 3M 1100C30 Orange, wired design, pack of 30

3M 1100C30 reusable ear plugs in orange are wired, reusable hearing protectors supplied as a pack of 30. Made from slow-recovery polyurethane foam with a tapered shape, they are designed to fit most ear canals comfortably and provide effective noise reduction for general-purpose use in workshops, home improvement and travel. The pack provides a convenient supply for regular users and visitors in noisy environments.

Advantages

The soft, slow-recovery polyurethane foam becomes more comfortable with body temperature and is hypoallergenic, offering extended wear comfort. The tapered design helps ensure a reliable fit while the smooth, dirt-resistant surface improves hygiene and durability. These ear plugs are reusable, lightweight and deliver substantial noise reduction for a wide range of everyday tasks.

Suitable for

• Workshop and construction tasks
• Using power tools, sanding, drilling and sawing
• Garden work such as mowing and chainsaw use
• Home improvement and DIY projects
• Travel and general-purpose noise reduction

When it may not be suitable

These ear plugs are intended for general-purpose noise reduction and may not be appropriate where certified, task-specific hearing protection is required (for example, very high-impact industrial operations with stricter PPE standards). They are not a substitute for custom-moulded or specialised hearing protection in environments with extreme noise exposure beyond the product’s recommended range.

Key specifications

• Material: slow-recovery polyurethane foam (hypoallergenic)
• Design: tapered foam with wired retention
• Colour: orange
• Noise reduction: up to 37 dB (typical reduction)
• Usable noise level range: approximately 95–110 dB
• Pack: 30 pairs per polybag
• Weight: lightweight for all-day wear

How to use

Compress the foam plug by rolling and squeezing with clean fingers to reduce its diameter, then insert the tapered end into the ear canal and hold until the foam expands to form a seal. The wired design helps retain the plugs when worn and makes removal easier. Follow the user instructions provided with the product; inspect plugs before each use and replace if soiled, damaged or if fit is compromised.

What to consider before purchase

• Check that the noise reduction level and usable noise range suit your environment
• Consider whether reusable foam plugs meet hygiene and replacement needs for your use case
• Confirm the tapered shape and wired design are compatible with your comfort and retention preferences

Usage recommendations

Read and follow all user instructions. For best protection, ensure a proper seal in each ear, replace plugs when dirty or worn, and combine with other PPE (eye or respiratory protection) if the task requires it.
