Great sound reduction - protect your ears!
Bought these when the inner ear foam pellets weren’t quite enough. This is a substantial improvement and are, in my opinion, for life. Great build quality as expected with 3M and these dampen the whole spectrum whilst also noticeably reducing the top end, which is what is likely to cause the most damage. I find I prefer taking them off or slightly removing off one ear when walking around the ground, just because it makes conversations easier to hear. Whilst they are big and bulky, they are light. I have found a comfortable position where they don’t get in the way of my shoot when the gun is pulled up to my face.

Excellent headphones ear muffs
I am very sensitive to noise this does a good job of blocking sound a bit basic but works very well

Great, but green, not black!
Great quality ear defenders and do almost as a good a job of ear protection as a the Optime III but in a more sensible size. Although note that the product description is slightly misleading - these have dark green outer shells, not black.

Fits a large head well.
Fit very well, on my large head. They're comfy so I am able to wear them for prolonged periods of time which is something I have struggled with in the past. I am really noticing the difference on my ears as I am able to wear these for a much longer period than other brands I have tried before.

Excellent product, decibel rating great good price
Brilliant, bought these to wear on airplanes to cancel out the noise of screaming kids. (Sorry kids I know you all get excited I did at your age) I put them over my ear buds lovely it’s like being cocooned in my own world for 4 hours. I’m used to wearing earmuffs, to be honest others could find them a little tight.

Mon mari ayant des problèmes de bruit porte constamment ce casque. Il est assez efficace (mais pour lui il laisse encore passer trop de bruit). Pour moi, c'est horrible de voir mon mari avec ce lourd casque se promener dans la maison (et même dans la rue ...). N'y a-t-il vraiment pas moyen de faire un casque relativement efficace (on ne sait jamais supprimer tout le bruit) plus "discret" (déjà le noir est très voyant, e métallisé serait peut-être plus "élégant" ?

Estos protectores auditivos funcionan de manera increíble, incluso mejor que otros modelos electrónicos que también tengo. La protección es muy superior y, al no depender de batería, sabes que siempre van a rendir al máximo. Se ajustan perfectamente a la cabeza y se pueden llevar puestos durante mucho tiempo sin que resulten molestos, algo que para mí es fundamental. Por comodidad, fiabilidad y nivel de protección, suelo preferir estos antes que cualquier otro.m incluso eléctricos. Muy recomendables.

...the metal part bends a bit too easily. I managed to bend it just by adjusting the size. You'll have to be a bit gentle with them, and that might not always be the case when out-and-about doing stuff.
