As the representative models for the LG Optimus 2X smartphone, Big Bang's G-Dragon and T.O.P first revealed their teaser for the "Knock Out" MV, while simultaneously promoting LG's newest product. Recently, an interesting behind-the-scenes video was revealed which focused on the 'making-of' for the "Knock Out" MV, as well as interesting snippets of how the LG Optimus 2X phone could be used. In both the teaser and the full music video, viewers have only been able to catch glimpses of the LG Optimus 2X, but in this latest video, they'll be able to see the product more as both GD&TOP are shown personally playing around with it. The capabilities of the product are shared, and it's certainly successful in drawing interest to the item. Check out the video below!
