After reading this thread I ordered the EFI's from aliexpress and I also ordered HM5 pads from mp4nation.
I am eager to try them asap but they will probably arrive in one month or so.
Sorry there is no info / URL as the jack was repurposed from a 3.5mm TRS extension cable. The hole in the ear cup was enlarged to accomodate the jack size and JB Weld epoxy was applied to the back.
You just cut the plastic away and unsolder the existing cable on the jack.
One like this would work perfectly but I imagine you could get one at a Dollar store near you easier.
hey i just got these for 19$(local mall in VietNam) will the Sony MDR-V6 pad fit?
