Awesome first impression and comparison, thank you. Based on my own experience, the harsh and grainy nature you speak of, as well as the bass being slow, are things that I found have disappeared over time. The concept of burn-in is real when it comes to these cans. So much so, I recall having initial buyer's remorse when I first purchased them because of those 2 aspects, as well as excessive clamping force (as I have a big head), but all of those things did disappear after about a fortnight of solid use. I genuinely feel they are the best sounding Bluetooth cans I have had to date. I 100% agree with you on the choice of material they used for the headband and the outside of the earcups. I worry it will fray over time.
I don't usually buy burn-in, but I will be keeping these around at least a little longer before I make a decision whether to keep them or not, so I'll see if my impressions change
