That's very interesting now, because a year ago I had exactly this mod with the same 3pin socket and the same custom cable made by someone else.
I had sold it back then but still have the list of parts used, so I chose exactly those componets and wanted to try it myself this time.
Thank you :)
Since I used the original connection socket of the DT 1770 PRO / DT 1990 PRO from the Beyerdynamic website (EAN 4010118910524) I assume that this picture here should represent the correct pinout of the 3-Pin Mini XLR jack.
The second picture shows how I connected the mini xlr...
I am planning to build my first own headphone cable for my modded DT770pro with 3Pin mini XLR connector and need help with soldering.
I bougth the following components for it:
Cable)Mogami 2893 Microphone cable, Neglex Quad Miniatur, 4.8mm
(Mini XLR Adapter 3 Pin) Rean RT3FC-B
(1/4 Jack)...
