Okay,
So it easy to find what.
Some Adresses are in Germany,maybe the Site are nit English but youncan contact the Admin a tell him what do younneed so it make you an offer.
You only need make a Cebel withe Nighthawk conector and the 4,4 mm balance conector.
What cabel do you want you can choose and the colors too.
I hope is helpfull.
if you ask stupidly you might be able to tinker yourself into one, or maybe you know someone?
If so, it would be much cheaper.
The plugs are not as expensive as the cable.
Should only be done correctly, it is not really difficult, you just have to know which cable is what and solder clean to the contacts.
Did two for my headphones myself took a little.
