HiFiMAN Edition X Planar Magnetic Headphones @ techPowerUp
 

HiFiMAN's newest high-end headphone, the Edition X, bears a striking resemblance to their flagship HE-1000. It uses the same driver design without the fancy nano materials found in the $1200 more expensive HE-1000, but is, at $1799, still the second most expensive headphone in HiFiMAN's line-up.
