Modifying the regular headphones to the balanced drive model.
You can modify the headphones if the L and R cable are separated.
In the case of a headphone which has one cable, until we cut the jack we won’t know if LR wiring is separated. If you cut and there are only 3 wires, you can’t
remodel to the balanced drive model.
In this case, you can only use regular headphones. Please back to new regular jack.
SENNHEISER HD-25-1 II is full independence of L and R wiring, and you can exchange the cable.
If you cut the mini jack and peel the wire, 4 lead wires appear as the bottom left picture.
The body of the SENNHEISER HD-598 has 4 polarities. You can
change the cable.
There is one LR cable, but there are 4 independent wires inside,
so as you can see from the picture you can remodel it to the
balanced drive model.
