It seems some of you don't really understand what Isone Pro is designed for.
It's purpose is to make your headphones sound like you are listening to speakers in a room, with the sound coming from the same position as speakers would in real life--in front of you on either side. The parameters in Isone Pro allow you to specify the distance of the listening position to the speakers, how wide apart the speakers are (this feature is coming), the size of the room, and also head/ear parameters to match your uniquely sized head and ears and how they affect what you hear in real life.
It's a tool for professional audio people who sometimes need to work on headphones, but have been wary of it due to the drastic stereo separation of headphones (no natural crossfeed like with speakers). Isone Pro takes it a few steps further beyond simple crossfeed and allow you to simulate specific listening environtments and speaker cabinets so you can check how your mix will sound on difference types of speakers, including common consumer ones like flat screen TV speakers, small multimedia speakers, car stereos, or even how your mix sounds when someone is standing outside the room. These are incredibly useful tools to the audio professional, because now they don't have to burn a mix every time and then go around to different parts of the house and to their car to check their mix in different environments and on different devices. All of these features are complete overkill and unnecessary for non-audio professionals or musicians, but typical music lovers and audiophiles can still benefit greatly from those features that are relevant to them--mainly the simulation of listening to speakers in front of you in a room of your choosing.
Some of you probably didn't read the manual either, thus not understanding how Isone Pro operates. In the manual, it's greatly stressed that the user match Isone Pro's parameters to the reference monitor speakers they use for audio work, so that when they put on headphones, it will sound as much like those speakers as possible in terms of cabinet positioning and room acoustics. That right away tells you what Isone Pro was designed for. If you don't even have reference monitor speakers in your setup, then you won't even understand that aspect of this plugin. But even then, you can still create an ideal listening environment via Isone Pro so that you can have the perfect virtual listening room every time you put on your headphones. It's not just a crossfeed plugin--it is a virtual listening environment simulator meant to sound very real.
