A challenger appears?
A patent published in Feb 2013 by non other than.... Sennheiser. I cant make out what the patent is actually saying, it seems to be mostly about some manufacturing method blahblah. But the second part of it is very planar-magnetic.
Oh GOD. That's definitely a planar driver.
Well. I don't know whether to be excited or pissed about this. On one hand, now we have another modern company making use of the once-abandoned planarmagnetic technology. On the other hand... well, it's Sennheiser. So along with that, we get their idiotic overpricing, somewhat disappointing build, and their house sound (which I personally find disgusting).
