TL;DR - they're worth $200, but don't give in to much of the hype.
I've been using mine for one hour per day, six days per week since the middle of December 2018. So far, I can hear what others are saying: they are warm, they are relaxed, and they do draw out some details. But there's a bit of confirmation bias in many of the reviews as well, and I'm not here to say others are wrong, but for me, I've heard better at the same price point.
I have a typical headphone setup: Topping D50, Schiit Asgard 2. However, I just could not get these headphones to open up and breathe for weeks and weeks. I was getting better detail, more punch, and brighter treble off my old AKG Quincy Jones, and my old Audio Tecnica 1000x headphones. These were not the usual Sennheiser warmth and brightness I had known from long ago.
So, I decided to pursue anathema, and got me a passive pre-amp EQ. (I know, I know, I'm evil). Only after putting the EQ in line after my DAC and before my amp did I hear what these headphones can do. They are much warmer, brighter, and cleaner than they were before the EQ. But that's the thing with these - I don't feel like I should need to EQ the snot out of them in order to get them to perform to the standards my other headphones can do WITHOUT the EQ. So I was a bit miffed on that.
Do they sound good? Yes, once the EQ is fully cranked.
They're not as detailed for classical music as I am used to, and the soundstage is a bit narrower than I was expecting, but reviewers who say they can be worn for long periods of time without fatigue are correct. If you watch your volume levels, and keep it reasonable, you'll enjoy these headphones for hours at a time.
For $200? Why not. But for me, the hype around them in all the five-star reviews is a bit much. Just keep that in mind.
