Dude... If SRS will give you their standard warranty service on the MSAs, I'd take that deal.
I love mine. They get duty at the range, mowing the lawn, out in the workshop... So comfy. I will note I roll with the neckband version. I really don't like the way over the head bands compress at my glasses contact points. Might not be an issue for someone that doesn't wear specs off of the range, though.
