Team members face off each other in the Knockout round. It’s like the Battle Rounds, except the hopefuls will sing solos. The coach pairs team members together. After they sing a song of their choosing, the coach decides who to send home.
By the end of the Knockout Rounds, 40 will become 20. It begins on Monday at 8/7c pm on NBC.
