While we don't make earplugs for airshows specifically, our EarPeace M for use with motorsports is best suited to be used at airshows. It is our most robust model of plug and comes with Medium, High and Max protection filters so you can choose the level of protection that you need. EarPeace allows a precise amount of unobstructed sound into the ear in a specific way so you can still hear clearly. They do a great job cutting down on engine and turbine noise. EarPeace ear plugs are also low profile and discreet. We are confident you'll love them.
