I still prefer my HD650 for casual extended listening because they are way more comfortable than my LCD2C. I find the Audeze are hot and clampy in comparison. The Audeze Cs can be too in my face from the top end so I tend to wear them for more intense listening over shorter periods of time. If I want to crank something up I put on the C's. I find with the LCD2C there's an edginess in female vocals and wind instruments that make them more present but a little irritating. My next purchase will be Clears and at that time I might even sell my Audeze LCD2C. I wouldn't ever think of selling my HD650 because I like them too much and not worth a whole bunch of money anyway.
