Duo Vital-x, real names Carmen and Vitalie Rosca, are married performers from Romania.  They have previously competed on the Romanian version of Got Talent.
Duo Vital-x's audition in Episode 1306 consisted of Vitalie placing a black bag over Carmen's head, who then threw knives at Vitalie who was standing in front of a board. The act ended with Vitalie ducking, and Carmen throwing a knife at where he was standing. At least three judges voted "Yes", sending the duo to the Judge Cuts.
Duo Vital-x did not perform in the Judge Cuts round, meaning they either withdrew or were cut by the judges before this stage of the competition.
