I guess a point could be made that most music is mixed and mastered on speakers, using headphones just for reality check or to pinpoint micro adjustments, and then subsequently the scientific approach of Olive and others craft their analysis based on speaker listening as reference. Now Is there a real validated science based reason for this or it's mainly historical? That's an interesting debate, we can point the issues of audio reproduction where the dimensions of the acoustic environment are significant compared to High frequencies wavelenghts, but, we can't deny that the Headphone/earphone market, despite that, is growing at a much higher velocity than the traditional way of speaker listening. So wondering if this down the line could lead to a paradigm shift, like, would the music actually sound different if it was mixed for headphone first, and for speaker as a side tought? I'm just being philosophical here, sorry If I derive the subject.
