I am using the Silencers. All of one day, yesterday, so far. I have been PMing with noharleyyet about them, so, in the interest of economy of one finger typing, I'll copy my notes here.
Well, I spent about 3.5 hrs with them. Me being me, I had them cranked to the max because I wanted to hear Gus's bells. They were a little more "hearable" but not a lot. I was surprised. My first impression was that vegetation I was walking through was ungodly loud. But after a while, i adjusted to that somehow. I was hunting in mostly big bluestem and Indiangrass cover. Very tall (7-8 ft), and heavy tallgrass prairie reconstructions. It was nearly dead calm but I think I could detect the wind noises even so. On a windy day, this might become a real issue.
While I could not hear Gus a well as I hoped, I could still figure out which direction he was at when I could hear him. I could also hear birds flush okay and turn to find them. So directionality wasn't too bad, but I want to play with them more before I get too confident with that.
I fired 6 shots (killed two birds, pulled feathers on a third, unfortunately). I thought the noise attenuation was not bad but I was focused on the birds, not the noise. I was shooting a 12 gauge with 30" barrels.
So, far, I think I like these okay. They are pretty slick the way they recharge in their holding box. They are reasonably comfortable too. My ear canals are not symmetrical. The right is much smaller than the left, so I used one medium and one small sized foam plugs and ear cups. Seemed pretty reasonable.
In short, I think they are worth what I paid so far, but I would be a little disappointed if I had paid the $216 that Amazon wants for them instead of the $120 I paid on ebay. BTW, that package was sealed from the factory, so seems like an honest and extremely good price.
I should add, my hearing is extremely poor. I should have been using hearing aids for the last decade but have struggled w/o them much to the dismay of my wife and others. Exactly how that affects how they work for me vs you may be strongly colored by that.
Anyway, that's it so far. They will be regular equipment for hunting, but I don't expect them to replace my muffs and plugs at the range.
