Because people are willing to pay it, that's why. If fewer consumers were willing to pay these absurd prices, these flagships would ultimately be less expensive.
I made this mini rant about the Westone W80's in the OT, that I think is also somewhat pertinent to headphone flagships too.
I find the above especially appeals to some recent Audeze trends and releases as well. The quality control, comfort and reliability of some of their recent flagships is honestly utterly bewildering, verging on pathetic, especially given the prices being charged. I'm also still surprised they're still sticking to the same overall physical design too. You'd think after all their success, they could have come up with a more ergonomic and lightweight design for the newer releases.
