Using a 3.5mm 90 degree adapter from amazon with my Moon Audio Blue Dragon cable that is for my Oppo PM-3. I already swapped the pads to the Shure Alcantara Ear Pads. Listening from Schiit Modi Multibit into Pangea Audio HP-201 w/ Sylvania 12AX7 NOS tube. I am a happy camper. Tonally it is what I think the Hifiman HE400S would sound like as a closed-back headphone. The earpad swap did not affect the sound much, but I hate velour against my skin. I experimented and so far am having the best results with the above combination.
dlanoI had to stretch and kinda flip the part that goes over the cup inside-out and then stretch over the cups, but I was able to get them to fit. I have them on like the stock pads with less overlap on the cups.
