The later quote sounds accurate. They are musical and satisfying to my ears, but that means nothing to the next person. We as people all hear different... at least this is what I think is true
And it’s a guess what anything may sound like until you try it on your own setup as well as a few others for good reference. Usually any audio show would never do justice to a pair of headphones.
One guy mentioned “wrangling” his big ears into the empyreans and it dawned on me that even these headphones with moderately roomy ear pads will not fit everyone and not work for everyone. But I understand the design concept to improve sound quality. It’s like being a basketball player and jumping into a tiny two seater sports car. Just doesn’t work for everyone.
