Review: 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.
Review: 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

### ⭐⭐⭐⭐⭐ 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!
*by R***H on 15 December 2025*

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.
