Arias, 32, faces the death penalty if convicted of first-degree murder in the killing of Travis Alexander.
Jurors on Tuesday were played sexually explicit phone conversations between Arias and Alexander.
The recordings ranged from raunchy talk to discussions about "Batman" and "Spider-Man" movies and Alanis Morissette songs.
Arias claims she killed the 30-year-old Alexander in self-defense. Prosecutors say Arias killed him in a jealous rage, stabbing and slashing him 27 times, slitting his throat and shooting him in the head.
Arias initially denied involvement before claiming self-defense.
