On your next outing, visit a museum near you and bring the Eversound system! Your residents will be able hear you talk about the different artworks/artifacts and stay connected even at a distance. Eversound also acts as a safety tool because when your residents can hear you, they are less likely to wander and get separated in unfamiliar settings.
Tip: There are all kinds of museums, many of them are free! Look for natural history museums, war museums, or art museums
