I don't find the CE6P bright and airy but rather warm and smooth. I think one of the 4 driver models may be more what you are looking for, at least that's what I gather from previous impressions. Maybe this will help a bit: http://cymbacavum.com/2015/04/25/quick-thoughts-cosmic-ears-ce6p-smooth-seduction/
Edit: The UE4 is considered a baby UERM by many.
Thanks for the link. My conclusion is that the CE6P is not for me then. It was very helpful
I will investigate the UE4. I havn't considered it until now.
