How to make custom cable adapter for DT 177X GO
The original bundled cable for DT 177x GO is very stiff and makes it a Desktop Headphones instead of a Portable one.
With this, you can bring DT 177x GO anywhere you want.
First, here is the diagram.
In case if you want to make a balanced cable with 2.5mm TRRS plug, you can refer to the following. Thanks to @DeepSpaceus for suggestion to add balanced.
You can use 4-pin XLR to TRRS adapter to connect to balanced desktop amp.
Now with these diagrams you should be able to create your own custom cable/adapter.
Here is what I made.

Here are what I had to prepare.
1 x TA4F 4-pin Connectorhttps://www.ebay.com.au/itm/BravoPro-TA4F-4-pin-Connector-for-Shure-Wireless-Systems-Black/3032985578961 x 3.5mm Female TRS Connectorhttps://www.ebay.com.au/itm/3-5mm-1-8-Female-TRS-Connector-Stereo-Audio-Jack-Plug-Yongsheng-YS240/2532989772193 x Breadboard cables (Any cable would do. The length of this is just perfect. Just remove the pin tip at both ends and you are ready to go)
1 x Tin Lead Rosin Core (Soldering Wire)
1 x 60W Solder (Higher Watt is not recommended)
1 x Heat Shrink Tube (The size and length will depend on your cable)
First step is to solder on the 3 cables to the TA4F.
As shows in the diagram, pin#2 and Pin#4 are shorted as this is common ground.
If you are going to attach a balanced cable, then take note of the diagram for the R+, R-, L+ and L-.
Once the cable has been soldered and you have shorted the pin#2 and pin#4 then you can put the covers back.
Next is the 3.5mm female jack.
You need to put the cover first before you solder anything or you will need to undo everything.
And this is also where you need to put the heat shrink tube as well. (not demonstrated here)
Then solder the cables referencing the diagram.
If you had heat shrink tube in place already then you can apply heat to shrink it at this point.
This is the final product.
(Update: I was unable to open up the 3.5mm jack to place the tube in place so I decided to put it over the whole thing and the result is as below. This is not exactly what was suggested by @GingerGroove In case if you are making yours, place the tubing as instructed in the above steps)
In case if your eyes are sharp and can do a micro detail soldering with thin wires, you can try getting one of these and re-solder the wires.
It is one of the things I purchased while trying to see if it would be compatible (eventually it was not).
I couldnt find a way to completely open this up so I gave up on these.
