I usually trust my ears fairly well, but I was wondering if anyone else had noticed this as I can't find any reviews online that stray from the standard belief that every generation of these headphones is better than the previous one. I bought the 1000xm3 but reluctantly returned them after a couple of weeks because I quite simply preferred the sound quality of the original 1000x that I have. I say reluctantly, because I really wanted to like them; they are much more comfortable and they fit my head better and the noise cancelling is also slightly better. But to my ears the gen1 version is far more tonally balanced with a lovely crisp, punchy detailed sound (for a closed back n/c design). The gen3 sounds muddy, with exaggerated bass in its non-EQ'd form. But perhaps that's what passes for 'improved sound' amongst many reviewers; more bass= better? Perhaps they are trying to match the sound signature of Beats Anyone else with me on this, or is there near universal agreement that Sony have improved the sound of these headphones with every generation?
