As opposed to the more common dynamic driver, the Edition X uses lighter and more responsive planar drivers.  These tend to provide much better sound but also come with a very hefty price tag, in this particular case an $1800 one.  That puts these headphones soundly into the audiophile and professional market as opposed to being intended for gamers.  In testing TechPowerUp found these to be not quite as clear as the HE-1000 model but they were more comfortable.  If you are looking for high end headphones or just like window shopping you can read the full review here.

"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."
