How the Battles work
Two men enter, one man leaves! No, wait, that's Thunderdome - but the principle is pretty much the same. The coaches throw pairs of their acts into the ring to sing competitive duets in front of the audience, with the winner of each Battle going through to the live shows - and the loser going home.
That means five battles for each coach - will.i.am, Tom Jones, Jessie J and Danny O'Donoghue - across the Saturday and Sunday shows, resulting in four teams of five.
The coaches will make the final decisions as to who stays and who goes immediately after the performances, but in the meantime they'll spend their time trying to develop their artists for the big nights.
Below you can watch again as each pair of acts performs individually in the audition rounds, read a short biography and vote (just for fun) for the one you think should make it through to the live shows. So what are you waiting for? Get voting!
