Usually, whenever I look at the Feenix site, they're out of stock but I've been creeping on the Aria for a long time now.
I really like the look of the headphones along with the high frequency response range and the huge drivers (also seeing now that it apparently includes a microphone as well, but I don't really see any specs on that). The whole line looks amazing, with minimalistic and modern designs that I feel would make my system look terrible by comparison.
