Looking for a short cable for the ATH M40X. It uses the turning lock type mechanism (like the picture). It is included with the M50X but not the M40X so I thought I'd see if anyone has one laying around or if you have ones from eBay. I think it is the same connector used on some Sennheiser headphones as well, but I'm not sure.
Let me know what you have and how much you want for it.
