The blind auditions are over and it’s almost time for the next round of competition on The Voice!

Coaches Nick Jonas, Kelly Clarkson, John Legend and Blake Shelton have set their teams and are about to trim them down a little.

The Voice battle rounds, coaches must put two, sometimes three, artists together to sing a duet in front of the studio audience. After their battle, the coach of those artists must choose one singer to move on to the next round.
