Which HPs were you mainly using prior to the Px8? Looking at your sig, if it was something like the HD800s/Aonic, I can understand. That was the case for me. I typically have a strong preference towards 'neutral' sounding cans e.g., HD600, NDH-30, S4X, MM-500, T3-01 etc.., so when I first tried the Px8, it felt completely off. It sounded very congested with overblown mid bass. But once I got acclimated to the new sound, it was rich and overall pleasing sound, albeit still a bit too intimate staging wise. Give it some time for your brain to catch up. If it still doesn't work for you, return it. I wouldn't pay attention to other reviews/impressions. If you take away all the sponsored reviews, hype, and biases, ain't much to look at anyways. If it ain't for you, it ain't for you. No need to conform yourself to "perceived" consensus.
