3M PELTOR Optime III Earmuffs, 35 dB, Black/Red, Neckband, H540B-412-SV

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.

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.

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

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.

These are great, i use them to cancel out hammer drill noise.

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.

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.

Didn't work as well as I'd hoped but I am dealing with noisy next door neighbours, so they are probably fine for normal everyday noises around the home. I did return them though.
