I was looking for a top of the line headphone that I would be able to wear for hours at a time. I hadn't been able to audition these before I got my own pair, and was initially worried that I wouldn't like the sound. I'm happy to say that these were phenomenal. I've used these to listen to pretty much everything at this point, and they've held up extraordinarily well to the breadth of things I listen to. For open-backed headphones, they block out a more ambient noise than my other open-backed headphones, but still provides a good sound stage. I do wish they were easier to carry around, but between the size and the open-backed sides, these are definitely not commuting headphones. While these sound phenomenal from a good DAC/AMP or DAP, I've found that my phone has enough power to drive them, albeit, with a bit of a reduction in dynamics.
If I had to have one minor issue with it is that, sometimes, male vocals get a little distant, but not so much as to be truly bothersome.
Overall, would not hesitate to recommend these headphones to everyone!
