Heavy-duty silence—Optime III earmuffs block serious noise and stay comfy through long shifts.
Used these on noisy sites, near generators, and during grinding work—these earmuffs mean business. 35 dB rating blocks out serious noise, and the double-shell tech keeps sound out without feeling bulky. Headband’s padded and adjustable—sits firm without crushing your skull. Cups seal well even with a cap or hoodie underneath. Red/black finish looks sharp and stands out in the kit pile. If you want hearing protection that’s comfortable, reliable, and built for loud environments, the Optime III is a proper bit of kit.

100% spot on!!
Spot on. Comfortable, size is perfect, cuts out noise just as the spec sheet specifies. Absolutely valuable for money. Designed so well. This is the same one u see being used by the airports as well, so ur ears are protected.

Great item
Bought these to replace my black/red ones which I wear for SantaPod. Wanted the bright green ones for a while & they finally got discounted! They are great ear defender, reduce the noise brilliantly but you can still hear what is going on. They fit my small head perfectly, so really pleased with them. The colour is really bright and loud, which is what I wanted. They are super comfy to wear for long periods of time if needed, great value for money especially as they were discounted, but if you were looking for great ear protection but wanted something bright, I would highly recommend!

Great ear defenders, but expensive replacement pads
Work on an oil tanker and these ear defenders blow away any of the other ones we have on board. All vessels I have been on have the Optime brands so they must be doing something right for their price point. Only drawback is that the “hygiene kits” which are the replacement pads are quite expensive for what they are which drops a star.

soft, comfy, excellent sound reduction
Adjusting these is a little awkward, and I found I had to bend them back a bit so they'd fit my big head, but other than this these are excellent. I had the 3M foldable ones before and the noise reduction wasn't as good, and they weren't very comfortable. These are soft and comfy, and muffle noises very well - it's makes my washing machine sound much quieter and also less annoying. The earmuffs also feel more roomy, so good for bigger ears. Glad I bought these.

Great for tinnitus sufferers and anyone who needs to protect their hearing
As a sufferer of tinnitus it’s a must have. I go to a noisy Church every Sunday and it saves my hearing from getting even worse

Excellent produit
Acheté à la lecture des avis précédents que je confirme: Amortissement exceptionnel des bruits environnants, le casque, certes volumineux mais d'un maintien parfait (ne glisse pas), est léger, ne comprime pas les oreilles, bien toléré sur une longue période de travail. Le système de maintien par la nuque permet de porter un couvre-chef. L'arceau rigide sur les casques traditionnels est remplacé sur le casque reçu par 2 lanières textiles avec velcro qui permettent éventuellement de le maintenir selon la méthode traditionnelle ( Cet accessoire ne figure ni dans le descriptif ni sur la photo). Un produit ultra-performant pour un coût modique.

Protezione acustica definitiva. Se lavori con decespugliatore e motosega, queste sono obbligatorie.
Uso le 3M Peltor Optime III da un po' e, per chi come me passa le giornate a usare macchinari rumorosi, queste cuffie sono la svolta. Dimenticatevi i tappi per le orecchie che dopo mezz'ora danno fastidio o che perdono efficacia: qui siamo su un altro pianeta a livello di isolamento. Perché le consiglio (senza giri di parole): Abbattimento del rumore: Quando usi il decespugliatore o la motosega, il calo di decibel è netto e immediato. Non senti solo meno rumore, senti proprio un silenzio profondo che ti protegge la testa dal mal di testa a fine giornata. Struttura e comfort: Nonostante siano ingombranti (perché l'isolamento richiede spessore, punto), le porti per ore senza che ti strizzino il cranio. L'archetto è regolabile e rimane in posizione anche se ti muovi molto o sudi. Qualità dei materiali: Le imbottiture attorno alle orecchie sono morbide ma resistenti. Non si sono ancora screpolate nonostante la polvere, il sudore e le vibrazioni tipiche di quando sei in mezzo al bosco o in giardino. Affidabilità: Sono costruite per durare. Non hanno giochi meccanici strani nelle giunture, il che significa che non si allentano col passare del tempo. I compromessi: Ingombro: Sono voluminose. Se devi lavorare in spazi estremamente angusti, tieni presente che sporgono, ma è il prezzo da pagare per avere una protezione di livello superiore. Calore: Essendo molto isolanti, d'estate le orecchie scaldano. Ma preferisco sentire caldo che tornare a casa con le orecchie che fischiano. In sintesi: Se cercate un giocattolo leggero per fare giardinaggio leggero, guardate altrove. Se invece usate attrezzi pesanti e volete proteggervi sul serio, queste 3M sono un investimento obbligatorio. 5 stelle meritate per la costruzione e l'efficacia brutale nell'isolare i rumori molesti.
