Hearing protection earmuffs 3M E-A-RCaps 7000089404 SNR 23 dB lightweight

3M E-A-RCaps 7000089404 SNR 23 dB lightweight earmuffs are compact hearing protection designed to reduce exposure to harmful noise levels while remaining comfortable and portable. The low-profile cups and lightweight construction make them easy to wear for intermittent or continuous use in workshops, construction sites and maintenance environments. With an SNR value of 23 dB, these earmuffs provide measurable attenuation for a range of common industrial and DIY noise sources.

Advantages

The earmuffs combine a slim, low-profile cup design with lightweight materials to minimize bulk and pressure on the head. Their simple, adjustable headband allows quick fitting and a secure seal around the ears. The noise attenuation rating of SNR 23 dB offers balanced protection for medium-noise tasks while preserving situational awareness better than heavily isolating models. The compact shape enhances portability and storage when not in use.

Suitable for

• Workshop and garage tasks such as sanding, grinding and light machining
• Construction and building maintenance with intermittent noise exposure
• Routine maintenance and service where hearing protection is required but bulky earmuffs are impractical
• Home DIY projects involving power tools with moderate noise levels

Key specifications

• Noise reduction rating: SNR 23 dB
• Design: low-profile, compact ear cups
• Weight: lightweight construction for reduced head pressure
• Fit: adjustable headband for quick fitting and secure seal
• Use: suitable for intermittent or continuous noise environments

How to use

Position the earmuffs over the ears and adjust the headband until the ear cups sit evenly and form a continuous seal around the ear canal. Ensure hair, glasses arms or clothing do not break the seal between the cushion and the head. For intermittent use, place the cups over the ears when entering noisy areas and remove them when noise levels are safe. Check cushions and headband condition regularly and replace any damaged parts according to manufacturer guidance to maintain effective attenuation.

Usage recommendations

Use these lightweight earmuffs for medium-noise tasks where comfort and portability are priorities. Combine with other protective equipment as required by workplace safety procedures, and replace worn cushions to preserve fit and noise reduction performance.
