3m cable for studio(6.3mm jack), 3m cable, 1.2m cable

Audio-Technica has released the Limited Edition headphone of the M50x, called M50xBL and M50xDG. (BL: Blue, DG: Dark Green)

In online communities, there was a claim that the Limited editions have more bass, compared to the normal M50x. 

To my ears, M50xBL has superior bass response compared to the M50x too.
