Any idea on an adapter that would work well with this 2.5 TRRS cable? It's already L shaped so it should be straight and short.

well search the thread for 2.5 trrs you will find some options as this was discussed before,
For me, i got a custom one from ted allen of headphone lounge for around 50$ an adapter from 2.5 trrs ak female to 3.5 trrs sony/hifiman male, if your gonna use it with sony only. To use it also with non balanced daps get it 2.5 trrs to 3.5 trs.
you can find in the thread other options for sale directly.
