Indy 500® Earplug

The AlpineThermoShape material molded to my ears after a few minutes and sealed out the drone of the engines completely. I could still talk to my buddy next to me without shouting, which surprised me. These are going in my race bag for every event now.

They stayed put all afternoon even in the heat, and I forgot I had them in during the race. The thermo-shape material really does mold to your ear without that stiff pressure I’ve felt in other plugs.

The fit is genuinely custom once the material molds to your ear, and I forgot I was wearing them halfway through the race. They blocked the roar enough to have a conversation but kept the rumble in the seat.
