I have the Hifiman HE400i's and i must say the ZMF Ori pads are the best earpads on the market for Hifiman cans, i have tried the following: Shitty velour HIFIMAN earpads, Focuspads (stock 400i earpads), Brainwavz HM5 Angled pleather, HM5 Angled Hybrids and finally Dekoni earpads.
Now I'm gonna describe my experience with each pair of earpads, Comfort, sound, fit (of the earpads on the headphones), construction quality and looks.
