In short:The 3M Peltor Optime I (H510A) is a lightweight headband ear defender with soft cushions and an SNR of 27 dB. 3M rates it for noise levels of roughly 87–98 dB, so it suits electric and battery trimmers and quieter petrol machines. For a loud petrol brush cutter used for long spells, check the sound pressure at the operator's ear in your machine's manual and consider the higher-rated Optime III.

Is it enough for a brush cutter?
It depends on the machine. Brush cutter manuals give two noise figures: the sound power level (LwA, often 104–115 dB(A) for petrol machines) and the sound pressure at the operator’s ear (LpA), which is the one that matters for your hearing. Battery and corded trimmers usually sit comfortably within the Optime I’s range. Many petrol brush cutters, especially at full throttle with a blade, are louder — for those, and for long sessions, the 3M Peltor Optime III gives more margin.
Fit and use
Wear ear defenders whenever the engine is running, not just while cutting — idling and revving up are loud too. Keep hair, hoods and glasses arms out from under the cushions, since gaps cut the protection sharply. Replace the cushions when they harden or crack. How loud brush cutters are, and what the figures mean, is explained in brush cutter noise levels and hearing protection.
Who it’s for
Battery and electric trimmer users, and petrol owners doing short jobs. Combine with eye protection — see the best safety gear for brush cutting — or choose a forestry helmet set that combines visor and ear defenders.
