Previously i got the earmax balanced 2.5mm which is not working perfectly so i send it back and got other nicer 2.5mm balanced which also wont qork perfectly so I send to a local guy to check is due to wrong connection in the wiring now running fine.So seriously you need to tell seller what headphone you use or what connection you want.
Yes yes. Exactly.
The pro82’s connector is settled 1mm inside the body.
So even with the right TRRS wiring mapping,
some cable won’t go all the way down inside the headphone’s jack, because they are too stiff. Which lead to mis-connection and eventually some unwanted shortcut.
