AudioTechnica ATH-MxCORD3M-C is a replacement cable (curly) for use with M50x and M40x headphones.
This cable is known as HP-CC in USA, and will work for a few of the M-Series models:
(note – because ATH-M20x and ATH-M30x have non-replaceable cables, this part not suitable for those models)
The curly cord is approx 1.2m in its “resting state”, but if stretched will be more like 3m
Includes the screw-on 6.3 mm (1/4”) headphone adapter
