I was considering whether the exclusivity on Drop.com makes it a negative in the sense of a highly reduced market outside of the USA owing to shipping costs and import fees, but then realized that the Aeon Closed X is the Drop collaboration version of the DCA Aeon RT anyway. There's a lot in common between the two with the Aeon Closed X going with a few tweaks based on user feedback whereas the Aeon RT allows for more cable options to choose from. The latter can be handy if you wish to use a balanced headphones output on your source although I haven't heard it enough to say how the Aeon Closed X drivers and pads differ from it to make for the final sound signature.

Speaking of which, this is my first Dan Clark Audio experience and I do see what others mean about DCA headphones generally using dampening materials to achieve the desired tonality. This makes for some of the best measuring sets in terms of frequency response or even adherence to targets typically used, but ends up being divisive when it comes to audiophiles. To some the Aeon Closed X can come off too damped or even muffled sounding to where it's hard to appreciate well-recorded tracks with plenty of dynamics. I had that experience too, and almost dismissed the set before realizing it now distinguishes itself from the current norm of such headphones by going for a warm-yet-relaxing sound. It's a very good all-rounder if all you care about is plopping down on your desk or couch and playing music in the background, as I am doing right now while writing this review! Understand the pros and cons and do read other reviews, since this is one of the harder sets to generalize how it sounds to others. Do also wait for the timely sale that takes this from justifiable for purchase to a worthy one, which is why I am going to recommend it too.
