I've been listening to the CRBNs all day, and my brain is getting more and more used to them. They sound really good. Somebody mentioned a "wall of sound" effect, and I think I know what they mean. The image of the music is like a painting, where all of the sounds fit together nicely as a whole. Other headphones have a more topology map type sound, where you can more easily see different aspects and there is a bit more depth.
The wall of sound effect is nice though, and really shows the various aspects of the music in one cohesive whole. It is a bit more difficult to simply target in on a particular instrument with some more complex compositions, but the CRBNs show how well the pieces fit together.
The CRBNs are some of the most comfortable headphones I've ever worn. I've had them on all day and haven't gotten a heat spot once. Also, I'm starting to understand the soundstage more now, and it actually is pretty wide (at least with my setup). I do wish there was a little more depth, but it's not a deal-breaker. The electrostatic bass continues to impress me. You can very easily hear bass guitars and bass drums. Electronic music and hip-hop sound pretty good actually, but other headphones do it better.
I listened to some albums with female vocals, and voices sound incredible to me. I think they are similar to the SR1as in that regard
Also, I tried the LCD-4 settings in Roon, and it did make everything sound thicker and the soundstage width increased. I like the non-eq sound better, as the resolution appears clearer
