For DJing purposes (I'm just starting into Latin music DJing, salsa and bachata), how do these stack up against the Pioneer HDJ 2000? From what I've read in the reviews seems like the HDJ2000 might have slightly better sound quality, but I'm not sure if it's worth almost twice the price for it...

Is there an update on this for the ATH-M50X? If there's another thread someone can link me to, that would be awesome :)
