Good points. I have to be sure that I make clear my own priorities, and I will certainly do so in my upcoming reviews of the Chord Hugo and Resonessence Labs Herus. I'm just not a massive "portable" kind of guy. I enjoy that sort of thing at times, and like you I marvel at the novelty of it, but it's not really a "lifestyle" for me as it is for some folks. And I can appreciate the differences in perspective caused by that fact.
Interestingly, I do listen to CIEMs in my home system. Not a lot of headphones out there that can match the speed and resolution of the top-tier models driven. Bonus points for not needing a monstrous amp to power them.
