OneVoice's audition in Episode 1103 consisted of singing Rozzi Crane's "Half The Man" as a group. Howie Mandel, Mel B, Heidi Klum, and Simon Cowell all voted "Yes," sending the group to the Judge Cuts. After the performance, one of the performers, Jeremy, asked another member to prom, and she accepted.
OneVoice's Judge Cuts performance in Episode 1108 consisted of singing as a group a song about waiting for a moment all their lives. OneVoice's performance was not strong enough for the judges to send it to the Quarterfinals, eliminating the group from the competition along with Cecile & Mighty.
