Quick note about pads - there was a drop last year i think when they came with lamb skip pads. These are simply amazing. I dont find the original pleather pads uncomfortable, but the lamb skin ones are much much better. If you guys are looking for replacement pads, I think these would be the best option since they actually improve the sound imo.
I have no idea if Chan still offers them, but you can ask.
Also, i'm glad to see people still ordering these and enjoying them in 2020. I've had mine for 2+ years now and i'm still very happy with them.
And if you have some worries about shipping or reply delays from Chan, do not worry, he is an awesome man in my experience but he handles a lot personally so that's why he might reply with a delay sometimes. When I ordered them back in 2018 there was no website, only massdrop and I found his email somewhere on this forum. At some point when the headphones were at customs in my country i needed a receipt that was missing from the packaging and I email him with an "urgent" tag and he called me in a few minutes and sent the doc, I think it was 2 o'clock at night in Singapore. And after about 8 months, because i'm stupid and i dropped them from my desk, a few days later one of the drivers stopped working - I emailed him, sent them under warranty for repairs, they replaced both drivers and said that one of the cups had a micro fissure and replaced the cups as well. He also sent another cable probably by mistake because i did not send the cable. I just paid for shipping from me to him and for the lamb skins pads ($50 i think). So, in my experience, he's an awesome man. And so are the headphones.
