While worrying about the prospect of having to memorize lyrics and prepare herself for a music video shoot, Futaba recalls when she took part in a drama CD recording alongside Rie Kugimiya. Futaba soon discovers that the manga she did the drama CD for is getting an anime adaptation, becoming excited about potentially working with Kugimiya again. However, Futaba becomes shocked when it is announced that the character she played in the drama CD will be voiced by Rin in the anime. As Futaba becomes depressed, uncertain of how to face Rin, her co-worker Hikari Shiodome tells her that regardless of what a voice actor goes through, it is their job not to let it show in their performance. Afterwards, Futaba puts aside her jealousy and looks forward to hearing Rin's interpretation of the character, allowing everyone to give their all for the music video shoot. However, the girls soon learn their CD's release date is being delayed.
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.
