Emma Willis hosts the third and final episode of the Battle rounds. Coaches Will.i.am, Sir Tom Jones, Olly Murs and Meghan Trainor all return to their infamous red chairs as the acts they have chosen from the blind auditions go head to head and fight for their place on their coach's team. The singers that impress their coach the most remain in the competition, but those that aren't so lucky can still be stolen by another coach.
Hosted by Emma Willis and Marvin Humes, the show features four musician coaches: will.i.am, Boy George, Paloma Faith and Ricky Wilson, who will coach only the most talented vocalists. The show's innovative format features three stages of competition: the first begins with the blind audition, then the competition enters into a battle phase, and finally, the live performance. The show's casting team is working with the music industry and searching the country for the best singers to bring to the blind audition process.
During the blind auditions, the decisions from the coaches are based solely on voice and not on looks. The coaches hear the contestants perform, but they don't get to see them - thanks to rotating chairs.
