Rin becomes troubled when her teacher suggests she attend a different high school, which would be beneficial for her work but also separate her from her best friend Sayo. As Rin becomes torn over whether she should continue being a voice actress, she is offered a role in an animated movie alongside Hiroshi Kamiya. During the recording, Rin struggles with playing the role of a 15-year-old, but Kamiya assures her that he too feels the pressure of living up to the expectations of all the other. After the movie recording, Rin decides to apply for a different high school, receiving full support from Sayo, who promises that they'll always be together even if they attend different schools.
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.
