So the Steven Slate Audio Company released some VSX headphones with modeling plugin to recreate different studio spaces and environments. The total price is $480 which includes the plugin. The actual headphones are VERY similar to $129 cans from another company as i've read in forums. They claim "The VSX headphone system allows you to create your music in precise models of pro mixing studios, mastering rooms, car stereos, nightclubs, audiophile mix rooms, boomboxes, and more. From anywhere in the world."
Never used this but Waves has something similar which I remember Andrew Scheps say he uses when travelling.
I don't see why more monitoring options would be bad. For sure, I use stereo full-range speakers, a mono mixcube, and at least two sets of headphones when assessing my mixes. I imagine that virtual emulations when using headphones could only help.
That being said, I've come to trust my mixcube above all else. I don't have fancy headphone software but when I trust headphones, bad things happen. When I trust a speaker, good things happen.
