3M PELTOR Optime I Earmuffs, 26 dB, Yellow, Neckband, H510B-403-GU

Easy to fit on new hard hat good secure fit and looks good too

Fits the petzl vertex helmet perfect 👍

Amazing products really good sound dampening can hardly hear anything really comfortable, but really unnecessary for the head strap I cut mine off with a razor blade. they hold onto your head themselves really well with no movement at all plus they are a real sleek design and gets people asking how they work ie stay on haha

Use them for paramotoring fitted a blue tooth radio system to them and they work perfect

I’ve tried a few different options and this is the absolute best. They’re great for autism and sound sensitivity. They’re good at blocking out noise and are even comfortable enough to sleep in. Wish they came in a more discreet colour but other than that, they’re great.

The muffs fitted easily on the helmet and are easily adjustable. Ideal for working in construction zones and plant areas. As with all ear defenders they can get a bit warm but are easily cleaned.

Bought them to wear whilst using a noisy food mixer.Definitely value for money.They keep the noise to a bearable level.Have also tested them on a loud fire alarm and again, keeps noise to a bearable level.The are fairly comfortable to wear for an hour or so, perhaps an hour and a half...they are lightweight and have a nice cushion.I suppose I have a small - medium sized head.I cannot imagine wearing them all day though, but then again, I cannot imagine wearing any over- ear ear defenders all day...which by their nature need to be tight to ensure a good noise-proof seal.

Have used these when doing general demolition with SDS drills and breakers and they are very good no noise gets through that I suppose would be damaging! Good thing about them is they fold up small so fit in tool kit neatly and thus the inside of them doesn’t get filthy! Only negative is they get a bit uncomfortable when wearing after maybe 2/3 hours but that may be due to my very large head!
