But this does not mean it is not secure on the head, right? More flexible, less clamping force, still secure and stable when worn ... sounds good so far.
Will you consider using the Woo-style stand where the headphones simply balance on it and doesn't clamp on side surfaces like Omegas
Not at all. It is very secure on my head. Most headbands use spring steel which creates more pressure the further you spread it apart. The bigger your head is, the greater the clamping force. The carbon fiber headband doesn't seem to exponentially increase the clamping force as much as a spring steel headband. The pressure still increases the further you spread it apart but, not as quickly. It is also very flexible in all directions (you can twist it quite a bit). Its rigidity is not fixed in one position like steel. You really have to hold these headphones in your hands to understand and appreciate this. I was a little skeptical of carbon fiber being used as a spring but, as it turns out its a great choice.
I have a Just Mobile aluminum stand that works fine with Audeze headphones. It also lets your headphones hang like the Woo Audio stand. I just got the Omega stand though, so I have to use it!
