With the anime she was working on ending, Futaba, who had failed her earlier audition, starts to fret about not having any more work in the pipeline once the web radio show ends. During the anime's wrap-up party, Futaba meets Banjo Ginga, who gives her some encouragement. Following the web radio's final broadcast, the producer reveals that, on top of the show continuing, he wants Futaba, Ichigo, and Rin to form a unit named "Earphones", complete with a CD debut. As each girl goes through their own worries, they get together for a magazine interview and feel relieved that they'll be together.
The series is centered on three friends who are all rookie voice actresses; Futaba Ichinose, Ichigo Moesaki and Rin Kohana. As the girls go through their individual troubles of working in voice acting, they end up hosting a web radio show together and form the unit, Earphones.
