## Description

3M PELTOR Optime III Earmuffs, 35 dB, Black/Red, Neckband, H540B-412-SV : desertcart.co.uk: DIY & Tools

Review: 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.
Review: 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.

## Questions & Answers

**Q: will they cut out quarrelling neighbours - and noisy traffic?**
A: Most of it definitely. Neighbours for sure and as for the traffic - depends on how noisy it is of course and how close to it you live. What even these babies can't block out completely is bass since we, the people, not only hear bass with our ears but feel it with our bodies and car engines can produce some fairly low frequencies. You should be fine from low mid to high frequencies so you won't know about the neighbours as long as they don't throw each other at the walls which would naturally produce some bass. ;)

**Q: Why SNR 5 db? Should it not be SNR 35 db?**
A: Yes it should be - Typo ...

**Q: I go to a church with very loud levels of live music.  Will the 3M Peltor Optime III be suitable for me?**
A: Technically yes - I use mine for when I go shooting at a range using military rifles; noisy would be an understatement. No problem, also you can hear normal conversation when wearing them. From a fashion standpoint - big and bulky. Horses for courses.

**Q: I work in live music - how much will these cut out? Ideally I want to hear very little**
A: I work in construction these will reduce the noise level but will not cancel everything out they are rated up to 110 db the next highest rating is for aircraft the optime 4 always look at the db rating
