The aim of the Seattle pop-up was to attract millennials and inspire them to visit a national park.

Current Studios created an audio loop of the sounds from the National Park Service’s Natural Sounds Division and embedded it into the headsets for the pop-up.

About 400 people tried out the headphones, and more than 5,000 stopped by the space to speak with brand ambassadors and foundation representatives about Parktracks and the agency’s birthday, as well as to learn more about the parks in the Seattle area.

Advertising for the pop-up included clever sayings like, “listen to rock. Like, an actual rock” and “listen to a rare recording of beetles.”
