Just curious if the additional ground would improve something.

Does anyone knows if we could do a custom cable using the 3.5 ground and thr 2.5 socket for a 4.4 port? Just like the adaptors for astell&kern and sony wm1a and wm1z? Like this one: https://shop.musicteck.com/products/pwaudio-ak-to-4-4mm-balanced-female-adapter
