STUDSON ED-2 Ear Defender (Dielectric)

My company bought us some studson hard hats because we can use them for climbing towers or work on the ground. They however don't supply the ear muffs, stating the 3m ear plugs work and that's what they buy. Whatever lol so I bought these and I enjoy them. They are comfortable and go on and come off the hardhat easily. These will also fit other hard hats like petzel, but are hard to take off. Good buy

Worked great. Doesn't block all of the noise but certainly makes it better and bearable.

One muff doesn't lock into helmet properly and falls off consistently

These worked reasonably well but as I turn my head side to side they unseat making them not good for me. I gave them to a co worker and they liked them well enough.

Expected more as these are supposedly made to work specifically with my Studson hard hat, just OK. Doesn't fit snug enough to reduce the noise it could with a bit tighter fit. Constantly coming out of the hard had slots when positioning them out or away from the ear. Kask brand protectors seem to work better for this particular hard hat.
