Has any one used sonice defender earpieces? Do they actually work? and how well do they work?
I have a pair. They fit better and are more comfortable than others I have tried. I have used them outside for pistol shooting and with muffs for carbine shooting. They do work. Well worth the $10 price, to protect your only set of ears. See Grant for a pair.
The reason I askis b/c i needto order the relaibilty package from grant and the shippingis like 7 bucks for a part that cost 3.50 so i was looking for something else to order along with it.
I just used mine today. I like them, very pliable and you can still hear normal conversation. I keep them in my go-bag. I had AR muzzles 4ft. to the left and right of my head today and was fine wearing them.
They don’t work on indoor ranges!
Sounds like a good reason to call and see if he’ll put it in an envelope and charge actual shipping. If not, buy from someone else. $7 to ship something that might cost a dollar to ship really chaps my ass, but I’ve heard of worse. Midway USA and Brightflashlights are great in this regard.
Yeah I’m still sour about paying $12 to ship 4 nuts that weigh less than an ounce ~240 miles. (car parts) Imagine my surprise when I got the invoice.
I already order them and got them in. I ended up doing a enough of an order to make it worth while. And hats off to Grant I got my stuff nice and fast and was able to put the reliability package in and go to the range and try out that and the Sonic Defenders the same day I received it.
We pretty much have a flat rate shipping cost so that means that if you order 500rds of ammo, you pay $7. Not a bad deal huh!

Grant it just gave me an excuse to buy more stuff and make it worth while. I have a question for you though. Will you ship P mags to the Peoples Republic of Massachussetts. If so I will end up placing a decent order of them 20-30
I’ve ordered from you. The flat rate shipping is great for the guy who wants the 500rds of ammo, bad for the guy who wants a set of ear plugs. Communist shipping? 
Very few people buy just one small item so the $7 shipping is generally not an issue. The other thing to remember is that there is NO insurance with the $5 shipping rates. All the packages that leave our shop via UPS have a minium of $100 insurance on it.

The 7 dollar shipping is no big deal. Frankly, it motivates me to actually purchase other items I need.
Grant’s shipped me a bunch of stuff in an order on a measly 7 dollar shipping cost, so I gots no reason to whine about it.
