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.

Good fit and comfy
Really good quality and durable I work on a water cutting machine that is extremely loud as these do the job I wear these for 10 hours a day and they are really comfy I bought a work friend then too who wears glasses and says they are fine with them due to been nice and soft and a good fit

Small tight headband with some adjustment
Great noise reduction and comfortable padded cups, but too small. I thought at first the headband was not adjustable at all, as the instructions are completely unclear, but I found that you can extend the narrow silver wire part in and out of the ear cup slightly. However in my opinion they are very tight. Obviously everyone's head is different but it's worth noting that not only were these too small for a large headed adult male and an average headed adult female, but they were also too tight for my ten year old who I was buying them for! I have returned these for the black ones with the green stripe (still 3M) which we have found are a much better fit.

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!

These work well.
They are well-made, do the job properly and fit well. I also use silicon ear plugs when using power tools but...belt and braces.

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.

The best!
Just about to buy my second pair, my current ones have had 5 years of serious daily use and are finally starting to wear around the ears. They are insanely comfortable on my massive head and make working with mega loud tools a breeze. Best I've ever worn.

Casque confortable et efficace, qui isole bien des bruits extérieurs. Je l’ai acheté pour dormir sans être dérangé par le bruit, et il remplit parfaitement son rôle.

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.

The reason for purchasing this earmuff hearing protection was for comfort and decibel rating. I wear hearing aids so wearing in ear hearing protection would not work for me. Looking at all the available earmuff type hearing protection the 3M Optima III had the best rating. Unfortunately they are not available in North America. I believe they don’t meet the safety standards for working on a job site because they restrict your hearing too much. These muffs are perfect for me. I am retired and spend five hours a day in my woodwork shop running very load tools. Table saws, routers, jointers and thickness planers. I wanted the best protection I could find.
