A subject dear to my heart, thank you @halcro for posting :)
For me the differences were not big (iphone6+apple earbuds) and had to switch back and forth several times. The most prominent is the "LF breathng" at 15K. It adds a very nice foundation to the sound, organizing it not only at LF but higher up in the spectrum. Add to the illusion of the recording venue. The bass (surprisingly) more controlled and (perhaps?) less boomy. In general, more involving and interesting presentation.
I'm not yet at the load play with my LDR but will try going down to 15K definitely!
