3M Corded Reusable Earplugs, 3 Pack, Noise Reduction Rating (NRR) 25 dB, Easy To Use & Insert, Pliable & Tri-Flange Design Enhances Comfort & Fit, Orange Ear Plugs (90716H3-DC)

What It Is

The 3M Corded Reusable Earplugs (90716H3-DC) are hearing protection accessories designed for use with any gas or electric lawn mower, string trimmer, leaf blower, or other outdoor power equipment. They reduce ambient noise by 25 dB to help prevent hearing damage during operation.

Fitment & Compatibility

• Universal fit: Works with any mower or outdoor power tool—no brand or model restrictions. No deck size, engine type, or OEM compatibility issues.
• Check your ear canal size: The tri-flange design fits most adults, but if you have very narrow or wide ear canals, test the seal before buying. NRR rating assumes proper insertion.
• No mounting required: These are worn in the ear, not attached to the machine. No adapters, brackets, or modifications needed.

Key Things to Know

• Noise Reduction Rating (NRR) 25 dB: Reduces loud mower/trimmer noise (typically 85–100 dB) to safer levels. NRR is a lab rating; real-world reduction is usually lower (around 15–20 dB) due to fit and seal.
• Reusable and washable: Rinse with mild soap and water after each use. Replace when flanges harden or lose shape (typically after 1–3 months of regular use).
• Easy insertion: The pliable, triple-flange design slides in without rolling. No foam compression needed. Cord helps prevent loss and makes removal quick.
• Common gotcha: If you have sensitive ear canals, the hard plastic core may cause discomfort after 30+ minutes. Foam alternatives may be more comfortable for longer wear.

Should You Buy It

If you mow weekly or use loud outdoor tools and want a low-cost, reusable, easy-to-clean hearing protection option, these are a solid pick. The universal fit and simple insertion make them great for quick jobs, but consider foam plugs if you need all-day comfort or have sensitive ears.
