For sale is a Transparent Ultra headphone cable set (2.0m). The cable comes with four different user swappable headphone terminations:

Mini 3 pin xlr for AB1266, etc.
Mini 4 pin XLR for Meze, Audeze, Kennerton, Heddphone, etc.
3.5mm for Sony, Hifiman, etc.
2.5mm for Hifiman, etc.
Amp end is terminated with 4 pin XLR.

I could not find the screw which locks the swappable part to the main cable, but it locks very tightly into place regardless, the screw is not really needed (unless you intentionally try to pull them apart). Original packaging is lost, the cable was purchased from F1 Audio in Palatine, IL (now renamed The Audio Experience).

Thanks for looking!

P.S. I'll close the listing on May 12th since I'll be leaving home for a long time, so grab it soon if you are interested!
