So, I bought the product "renewed" or "refurbished", so let's get that out of the way first. The left ear cup has a tiny bit of "fold" to it on the backside, but doesn't interfere with fitment in the least. I don't wear them for the looks anyway.I own roughly 16 pair of headphones, most studio-grade. Not gonna go through the list at this time.These headphones are ?????? the most comfortable pair I've ever owned, hands down. I especially enjoy the fact that the earpads are very easy to cleaned, which can't be said of headphones with velour earpads (I'm looking at you, Beyerdynamic). I have normal-sized ears and though the sides of my ears do occasionally brush the inside edge, depending on what I'm doing, it doesn't irritate them. They also do not get hot in any way, but I live in a home with a stable climate, so keep that in mind.The sound is great. At first, I had to reacclimate to "flat" sounding headphones, though the claim that these cans are closer to the "Harmon Line" than others seems to be true enough. The best part is that they REALLY shine to some decent amplification. I don't really use a dedicated DAC, since I really don't need one (high quality motherboards nowadays do just fine IMO). Music and movies really "pop" in a way they haven't before, though that's with casual use. During any editing sessions I find myself in, I find myself using less "corrective measures" when dealing with loudness or distortion, which is a ??? ????.Since they are closed-back, one would wonder about the sound isolation of their surroundings, and I will say this does the job quite well with the included earpads. They conform nicely with the sides of my head and while they still let some frequency ranges through, none of them interfere if I'm actively listening to anything.These are top-tier for anything with podcasting or single-instrument recording w/ feedback.HIGHLY recommend.
