i've just sent of my headamp tour pair of 560's, and here are some thoughts:
first off i'd like to thank justin at headamp for the opportunity to hear this headphone in my own house, and with my own gear.
i'd heard the 560 briefly at the nashville meet, just before i received the tour pair.
i'm not one for writing "reviews", i'm not that eloquent in describing what i'm hearing.
the other headphones i have are the grado gs1000e, and the lcd x, so the 560 was up against some stiff competition, not that it was really a competition to begin with.
the 560's are very comfortable , very light, not as comfy as the grado, but more comfortable that the lcd x, weight wise.
the pads on the 560 weren't as nice as the audeze, but then, it's half the price.
now for the sound.
the 560 fell somewhere in between the grado and the audeze to me.
it had the speed, articulation , of the grado, and its soundstage was more akin to the audeze.
bass reached low, and was tight, tuneful. mids present, treble extended, and not harsh.
i've heard all the hifiman headphones, my favorite being the he-6, when its properly driven, which can be difficult .
other than the he-6 amped right, this is the best hifiman i've heard.
to have a headphone, sound this good, sound approaching the quality of my favorite , the lcd x, at roughly half the price is outstanding !
i haven't had the pleasure of buying anything from headamp as yet, but that may change , the 560 is that good
