Hearing protection for loud garden tools
These over-the-head ear muffs carry a noise reduction rating of 27 dB and are built for homeowners and landscapers who run mowers, blowers or chainsaws. They reduce harmful sound levels so you can work comfortably for longer periods.
Sustained noise reduction on extended jobs
The NRR 27 dB rating applies to continuous exposure from engines and cutting tools rather than brief impulses. The padded headband and ear cups maintain their seal during hours of vibration and movement without slipping.
Check head fit and accessory compatibility
Verify that the over-the-head band clears any hat brim, helmet or safety glasses you already wear. Ensure the cup depth accommodates your ear size so the seal stays intact while you turn your head.

Questions about this item
How much heat builds up around the ears during all-day wear?
The over-the-head design uses passive cushioning rather than active cooling, so warmth depends on ambient temperature and personal tolerance.
What must I already own for these ear muffs to function?
Nothing — they are a self-contained hearing protector that requires no batteries, cables or external devices.
Will the 27 dB NRR still protect me if I also wear safety glasses?
Thin temple arms usually fit under the cushions without breaking the seal, but thick frames can reduce the effective attenuation.
