Audio-Technica has just announced a new line of M-Series headphones that will add different price and performance tiers to their existing and widely popular ATH-M50x headphones. The ATH-M20x are the entry level headphones that have 40mm drivers and will cost $69. The ATH-M30x adds better and louder sound at $99. The ATH-M40x adds slightly better drivers, a fold-hinge construction, and a removable cable for $139. The top performing ATH-M50x adds bigger bass booming 45mm drivers for $239.
As you can see, there is something here for every price range and AT has been around for a very long time. I bet they will all work nicely in the studio or the DJ booth but I'll reserve judgement until we get them in lab once they are released shortly.
