as ifi xDSD user …
payed for my 3.5 TRRS balanced male to 4 PIN XLR adapter 20 bucks at venture electronics and 40 for the cable version at oidio sound uk
there are some 2.5 TRRS to 3.5 TRRS balanced adapters for under 20
I got once the Massdrop set “MEE AUDIO MMCX BALANCED AUDIO CABLE W/ ADAPTERS” for 80 bucks
here you also get a 45 degree angled 2.5 TRRS female to 3.5 TRRS male adapter and a pentacon version as well
they have the 2 PIN version as well
you can find the same set on Amazon - at least on Amazon Germany
