The Voice season 27 turned up the heat Monday night (March 10) as the Battle Rounds began, pitting the Top 48 contestants against each other in unforgettable duets to secure their place in the Knockouts.

Coaches Adam Levine, John Legend, Michael Bublé, and Kelsea Ballerini each paired their artists strategically, but it was Team Adam’s matchup between Fran Posla and Ethan Eckenroad that sparked one of the evening’s most memorable performances.

Performing Noah Cyrus’s emotional hit “July,” Posla and Eckenroad showcased distinctly different vocal strengths on the soulful track.

Posla, who Levine encouraged to sing slightly sharp to maintain pitch—advice he insisted “makes sense” despite the initial confusion—captivated the audience immediately with her crisp tone and confident phrasing. Her cool, laid-back delivery earned her praise across the board, with Kelsea Ballerini enthusiastically describing Posla as the “ultimate cool girl,” jokingly adding, “I want to go drink a bourbon with you, and I don’t even drink bourbon, ’cause that scares me.”

Meanwhile, Ethan Eckenroad, who has spent considerable time away from his wife and infant daughter during the competition, brought a softer, emotionally charged vocal style that gained momentum throughout the performance.

While he initially struggled to find his footing, Eckenroad eventually won over the coaches with a soulful climax that highlighted his vocal warmth. Michael Bublé particularly praised Eckenroad’s voice as “soft and beautiful,” recognizing the hidden power beneath his gentle delivery.

However, it wasn’t smooth sailing for Eckenroad from the start, as both Legend and Levine acknowledged he took some time to find his groove.

Legend noted that while Posla appeared effortlessly comfortable with Noah Cyrus’s track “July,” Eckenroad’s initial uncertainty was apparent. Ultimately, Adam surprised viewers with his decision, advancing Ethan Eckenroad to the Knockouts while eliminating Fran Posla, despite universal acclaim for her standout performance.

Levine appeared conflicted, reflecting openly: “Fran, you really did thrive singing this song. Ethan, it’s not that you didn’t thrive, because you did…but it took a little time.” Despite second-guessing the song choice, Levine placed his bets on Eckenroad’s growth potential moving forward.

The Voice Season 27 continues next week as coaches Legend, Levine, Bublé, and Ballerini guide their artists into the Knockout rounds, inching closer to crowning the next vocal star.
