The "battle rounds" continue and the coaches enlist the help of the music industry's top recording artists to offer their knowledge and skill as advisers. Adam Levine teams up with Hillary Scott, Blake Shelton with Sheryl Crow, Shakira with Joel Madden, and Usher with Pharrell Williams. In this phase, the coaches pit two of their own team members against each other in a dueling duet. After the vocal face-off, each coach must choose which artist from their team is the strongest, and has the option of stealing losing artists from an opposing coach. Each coach has two steals during the battle rounds where their artists will proceed to the new knockout rounds.
