I've tried several of the inexpensive versions of electronic muffs/plugs with horrible experience. My beef centers around sound quality.
GOOD -- I bought one of the well under $200 units. You'd recognize the brand. It was junk. Gave it away to a LRH member.
It did not bock blast well at all. And it was one of the exterior style, designed to wear behind the ear. It would dislodge and then not seal the ear canal.
Worthless! No that's wrong. It was WORSE than worthless since it gave you a false sense of protection.
