so the 500 really hits harder than the 700? how much more notably so? and how will the 500 compare to my 518s?
Oh, I was comparing the XB500 to AKG K518 in my last sentence, perhaps you interpreted it as XB500 vs XB700 which I wouldn't blame you for the way I wrote it.
To try put things into perspective let me illustrate a bit:
Bass quantity
Bass neutral |-----M50---------------------K518--XB700---------XB500-| Most bassheavy
Deep upper/bass ratio, tonality of the bass (relative only to the headphone's own deep/upper bass skew, nothing about strength and can't be compared between the different headphones)
K518: 35/65 % (deep/upper)
XB500: 45/55 % (deep/upper)
XB700: 70/30 % (deep/upper)
The AKG have more impact than XB700 from typical bass notes, in subbass like dubstep genre the XB700 excells AKG K518 greatly but this kind of bass is still "softer" sounding and to many get confused when comparing mid/upper bass vs subbass as different headphones have such different emphasis in the bass range. Then again XB500 has like a bit more mid/upper bass as well as A LOT more subbass compared to K518 and compared to XB700 it has about same or just a tiny bit less subbass while having significantly more mid/upper bass. I concider XB700 to have more of subbass than AKG has more mid/upper bass than it so therefore I'd put XB700 as being slightly above AKGs but since XB500 has about the same amount huge subbass amount of that of XB700 + LARGE amount more mid/upper bass then it becomes siginicantly more bassy than those two.
Finally here's some graph from headphone.com but the graph isn't telling the whole story, the AKG K81 (which is the same as K518) is a lot bassier than the graph may suggest comparing to XB700/500.
I was slightly dissappointed with XB700 regarding mid/upper bass as several of my previous headphones had more impact due to the stronger mid/upper bass as I prefer a balanced deep vs mid/upper bass which XB500 has, only the whole bassrange is boosted greatly but it's very evenly so (well to nitpick boosting it evenly all the way to 300Hz causes some issues as that's already whereabouts the lower mids starts and this will lead to some midrange bass bleed unless taking care of it with EQing, optimally it should have started rolling-off somewhere in the 200~250Hz region).
