Thanks, going to put mine in a balanced configuration later, so just wanted a heads up.

Sorted out the headphones so they are able to do both 3.5mm single end dual input and balanced 2.5mm dual input, few details and pics for those interested.

Left side just leave the two wires from pcb to driver, red L+ copper L- = tip and sleeve.

removed to cable bung from top of cup.

added a square of 3m double sided tape.

followed by a thin piece of sticky back felt.

put it back together and cut out a small piece of the same felt and plugged from top.

right side remove all spare wires and the R+ as its linked to the ring, you can leave this if you want but I want to have it terminated as R+ tip R- sleeve as the left side, plus the cables I have for other headphones are set like this (quite a standard wiring set up ) and for the sake of changing one wire it's a no brainer imo.

Removed the pcb to solder it just to make sure I don't clip the cups, I metered the pcb to find the R+ track and after soldering it just check I was getting around 30 ohms before putting it back together like the left side.

Just re soldered the ground wire ( not happy with the stock solder joint) 3.5mm blank Jack to check pinout.

Trimmed back the old cable on both sides of the headband, no point opening up the band to remove the cable fully. Might do if I change the band at a later date but for now no point making more work for myself.
So now you have both sides independent of each other and in true dual balanced config or dual single end depending on what you source / cable is your going to use, took around an hour to complete and after comparing single to balanced on the M100's it was time well spent. But I knew that before I stared as I've been using balanced for years.

How a pair of headphones should really look, no horrible bits of cable from top of cup to cup.

How the sound? Is it better?
Yes, early findings are they have better separation and more power ( 30%) sub bass and bass are tighter and better separation, vocals are precise and on soul / R&B tracks they are clear and smooth sounding. EDM keyboards sound great. Still need to burn them in as they were fresh out of the box when I modded them, so will give a bit more time and see what changes.
