OMEGA X is changing up the atmosphere for a cool, sleek new set of concept teasers, ahead of their 'What's Goin' On' comeback.

Unlike the dramatic and intense mood seen in their 'E' version concept photos last week, OMEGA X members Yechan, Hyuk, Kevin, and Junghoon displayed the cool, charismatic charms in front of the camera as they posed in a light blue backdrop.

Meanwhile, OMEGA X's first official comeback since their debut with their 2nd single album, 'What's Goin' On,' is set to drop on September 6 at 6 PM KST.
