The HC-9 is compatible with the newer Hifiman HE4XX runs as well as many Focal designs etc. The cable features dual 3 pole TRS connectors and terminates to a female 4-pin mini XLR. This is a balanced cable, compatible with our entire interconnect line.
If you want this cable for your Sony or Beyerdynamic headphones, we'll most likely need to build that for you through the custom shop.
We have two styles available for our headphone cables. Our standard 4.5 ft full length cable, which terminates to our standard female 4-pin mini-XLR. And alternatively we offer an 18" split only version, which can be paired with a 3 ft version of any of our six main interconnect styles.
If you want to pair your headphone cable with our multi-kit, it's best to choose the standard 4.5 ft version, OR add an IC-7 Interconnect extension to your order if you want the split only headphone cable with a multi-kit.
As usual if you'd like a different color, length, specific termination, or our old "standard" low profile heat shrink split, shoot us an email at the custom shop.
