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 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.

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.
