Ever since their time spent on 'Produce IOI Season 2,' NU'EST have climbed to the top and have become one of K-Pop's up and coming groups to look out for. However, things might not have been so great when their audio failed during a recent performance.

On August 31st, NU'EST W, their newest sub-unit, performed at the COEX Convention & Exhibition Center in Seoul, Gangnam for the 'FIFA World Cup Qualifying Match.' During the outdoor performance, the audio completely cut off during their performance of "If You."

At the 1:14 mark, the audio cuts during Baekho's part while Aron, JR and Ren look completely taken back by the sudden disturbance. However, they boys became nothing but smiles because of their fans' reaction.

Almost instantly the majority of female fans fill in for the singers and begin singing along and carrying their song. You can tell how much they care about NU'EST as they sang every line and hummed the melody and even began cheering as the boys gave a thumbs up of approval!

What do you think of this alarming incident turning into a charming experience for NU'EST?
