I'm no headphone expert, but I just got the P7 and love them. I have nothing else to compare them to. You can see my audio equipment in my signature. Compared to that, I really like these headphones. I plan on using them with my Note 4 on my trips, with my Macbook Air, and sometimes connected to my C2500. Mind you, I got them for free with points from a credit card. Knowing then what I know now, I would pay the $400 for them if I had to.
