I received the mighty plugs, in exchange for honest review. The mighty plugs are moldable. They also come with a carrying case. You get two ear plugs, a carrying case, and the instructions.
I struggled with molding the plugs and I struggled with sealing the plugs. I am still practicing getting the right mold and fit.
The ear plugs start out as round discs. You have to mold and shape them for your ears, then seal them in. I wanted ear plugs to help sleep sometimes or when the kids are extra noisy, I can block them out. It also would have helped to block out noises on the fourth. Between the fireworks and a few neighbor parties, I needed to block out a lot of noise.
