Hello everyone, I'm looking to buy an ATH-M50x. I know these were released in 2014 and that new colors (and the M70x) were released in 2015. I just want to get the black one. Since this headphone has been out for longer than a year I wouldn't like it when I bought one and a month later or so a new version is released. I have no idea how the release/product cycle of Audio Technica is concerning these headphones. Does anyone have more info on that? Thanks in advance!
