The electronic earmuffs I use as loaner units during classes are on sale at Midway USA until April 30th.
For the price, they are VERY hard to beat. I bought a pair of inexpensive earmuffs from a local big-box store before I got these. They were twice the price of the Midway product, but I returned them because they worked so poorly.
FTC disclaimer: there is no material connection between me and Midway USA other than me buying their products at the same prices available to all other Midway USA customers.
