The girls assemble at the same studio for separate jobs; with Futaba dubbing a foreign horror film alongside Rikiya Koyama, Ichigo recording an audiobook, and Rin doing a game voiceover. During the dubbing session, Futaba runs into some issues, as well as some pressure from another voice actor, Yamori, who doesn't think much of her, but manages to pull through. Meanwhile, Ichigo has to try and voice in a lower tone than usual while Rin tries to perform reactions to different levels of attack. At the end of the day, each of the girls manage to finish their respective jobs in one piece, with Futaba receiving compliments from both Yamori and Koyama.
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.
