The contest heats up as the teams assembled by Tom Jones, Will.i.am, Jennifer Hudson and Olly Murs enter the Battle phase. Here, the coaches are tasked with chipping away at their roster of would-be stars via head-to-head studio battles. Each of the coaches are given `steals', which gives them a chance to save any of the acts knocked out by their rival coaches during the sing-offs. As the contest gets ever fiercer, Emma Willis will be on hand to congratulate the victors, and commiserate with their defeated rivals.
