These are used sound protection ear muffs for use in the weapons range or whenever shooting a weapon.
These are passive and we replaced them with electronic units that allow the user to talk and these electronic muffs instantly shut off the shot noise. Electronic Muffs are almost essential for large caliber weapons.
These Passive Muffs for noisy environments - machinery, auto and outdoors.
Passive Muffs cost about $20 and active units from $40 to $60 and up.
I have about 25 pair that are in good condition and will protect your ears from most irritating noises!
They worked well in our range but the electronic Muffs work really well cancelling the larger caliber weapons and allow you to talk and listen to others talk in the middle large caliber rifle fire!.
