Okay, after some more listening to the Clear Pro, I am convinced break-in is a thing.
At first they were obvious just a tick bright with an 'edge' throughout. The bass was fairly anemic, but after putting probably 50 hours on them since they arrived, that is changing. They get smoother every time I listen, and the bass is coming into its own. Treble still slightly edgy or maybe a bit grainy is a better way to say it. But, its gets better every time I listen.
The real eye opener was going back to listen to my Audeze LCD-X. Whoa! Sounded so much different, and there really wasn't anything that stood out over the clear other than bass punch. But the Clear strikes back with a cleaner bass. I don't know if harmonic distortion measurements would show a major difference, but the only instrument that matters... my EARS.... say the bass is much more natural and refined.
Overall, I hate to say it, I think they are more than just a marginally better headphone that the LCD-X. The overall increase in listener enjoyment has me probably putting the LCD-X up on the Head Fi market, if you are interested!
