Finally my pair came in. Excellent build quality many previously have mentioned. But something strange, it seems the modulor pair is noticeably stiffer than my regular pleather pads. In fact they seem a lot like the stiff velour pads . If someone hadn't told me they were jergpads I would have mistaken them for stock velour. It kind of boggles my mind. I'm thinking it may be because they've been outside in the mailbox all day, so maybe the cold weather is to blame. I'm hoping with time and heat they'll get softer.
Sound wise, they sound identical to my personal made jergpads I did many months back, but of course they feel and look much more professional. The current version of the mod has come a long way compared to v1 which I did. I opted to not do the back vent mod because I want full bass extension so I taped the entire circumference down with the provided tape, sub-bass seems improved. I think my attempt at the sub-bass mod with my older pair wasn't the best.
Overall very happy with my jergulors :) I've already found a new home for my old pair, in a drawer!
Hifiman pleathers have heat-activated foam so yeah, just wear them and they soften up like magic.
