Don't you need studio quality headphones to do this kind of work properly? The audio quality seems like a limiting factor with the headset. I work in visual arts and while I agree the idea is intriguing, I somehow doubt the VR headset will be as well calibrated and adjustable as a high end monitor.
I’d be more concerned about audio latency than quality at this point, when tracking at least. Clean, isolated sound when tracking is important, but mixing is where quality and accuracy come more into play, and I can’t see these playing any part of the audio portion of that. Could still move virtual sliders around a virtual mixing desk and run on proper studio monitors though. Again, there are a tremendous amount of “ifs” for this product, and just because something “could” be interesting doesn’t mean it will ever pan out into a good product. I’m still pretty skeptical, but we’ll see soon.
