Combined with sophisticated noise cancelation and other relatively mature tech, this could make intentional focus listening possible, analogous to looking at something, as well as closing your eyelids, but for hearing. Imagine being able to shut off specific ambient noises (and sometimes.. people) without losing spatial awareness. Or tune in a source you're paying attention to (the cocktail party problem). The issue with super-hearing would be to re-adjust expectations of who can reasonably hear us. Could be used for creepy things, obviously..
