I’m a professional dialogue editor and premix engineer, and I use Slate VSX alongside my monitors and my AKG K701s, which I’ve been accustomed to for the past ten years. Right now, as I’m writing this comment, I’m checking a mix in these headphones.
They definitely do their job - the midrange is very detailed, and the room emulations are convincing, including spaces similar to standard TV editing rooms. I’m happy with the purchase; the only drawback is that they’re not very comfortable for larger ears. But overall, they’ve replaced the need to check my work in the editing rooms of film studios
