Have to say, the only thing better about the 560 is, for me, it's more comfortable. I had to put a wrap around the head band of the HEK (was suggested on one of these HEK threads), spreads the pressure across my bald noggin and helps (the pressure and discomfort is right at the top of my small, smooth head, and is worse the smaller I make the band. Much better wrapped, though. Add some cheese and salsa, makes a nice sandwich
) . But, have to say, almost everything I listen to sounds a bit muddy since I got these. Put them on my wife's ears, put on Ella and Louis for her, even she was wowed (and she's heard some good gear-mine, of course-over the years, usually doesn't particularly care a whole lot. She was stunned by the clarity and realism of these. So, long winded answer, they'll be my birthday present to myself (someone has to do it), with the ZOTL driving them. Definitely miss them on vacation. Using Beyer 1350, FAD Heaven V, Pono, other iems, good gear, all ruined for me, sad...
