Do you have these Marantz MPH-2's? You've tried them? Very interesting... Can you give more detail about how they sound?
(I've been jonesing about these for weeks, but afraid of ending up w/junk)
They must be a rebrand of the
ISK mdh9000's, which as someone else pointed out on the Takstar thread, are pretty much only available in the U.S. through Aliexpress:

The same 'phones (they sure look the same) appear as
LyxPro HAS-30: available on Amazon for ~$50 including shipping..

And for even less money (but possibly lacking that locking input jack) as
Stellar Labs (HC-5985) on the MCM Electronics website as Part #35-5985.
