Are you worried that when you watch movies and TV shows, the lighting, the choice of camera lens, the color grading, the special effects, the editing, the acting, the directing, the sound effects, the score, etc. all will lure your brain into acclimating to super-stimuli and thus reality will lose its luster in comparison? Will you stop watching all movies and TV shows because it's all "created" as opposed to natural? The purpose of Isone is actually to make headphones sound MORE natural, not less, in the context of how we are used to hearing audio played back by speakers in an acoustic setting. Headphone listening have always been criticized for sounding unnatural due to the complete disconnect between the two channels, which is nothing like how our auditory system works, and Isone was created to remedy that shortcoming. Isone is much more than just a simple crossfeed, because it also creates a believable acoustic environment (and a wide range of them for you to choose from, and customize), which is what our ears find more natural, since that's what we are hearing all the time when we're not wearing headphones.
