Feint (Andy) shows off his new headphones. Which are the Audeze EL-8 headphones

At time stamp 2:51, Feint is seen using Ableton Live for a mix. Given the recency of the video and lacking distinguishing features of a previous version, it's likely Feint is using Ableton Live 9.

In this Facebook photo, Feint posts a cropped image of his work-in-progress in FL Studio. The photo date comes before the release date of FL Studio 11, but after the release date of 10. Therefore, the latest version Feint could be using in this photo is FL Studio 10.

Feint says in this Facebook post "working on newish stuff... x", we can see that he's using Logic Pro X in the video.

In this photo posted on Feint's Facebook, Feint's reaction to his newly acquired HS80M monitors is "hnnnng".
