can u compare it to re 400??
hope this is not rude but this was my response about 10 pages back i think
i have both well the be edition for the gr07
i find the be gr07 is better all rounder, the bass is fast and punchy from what i'm reading here the sheer speed and fast decay is the same just the amount of impact is different for the bass (be obviously having more) i think its better for more modern music, edm, pop, rock etc
the midrange i felt is not really that recessed at all, compare the the bass
comparing the midrange to the re400 well, without the bass boost it made the vocals more clear and actually with the delicate treble response made the depth and height of the soundstage spectacular
the gr07 be had a little siblance in the treble compare the smooth and delicate treble of the re400. i got use to it so its not really a bother but if you a/b them its quite obvious. but if you listen to a lot of rock (it can get a bit harsh fast). the re400 to me is better for vocal music and slower to medium tracks.
the soundstage on the gr07 be is rather wide, it would be a lot airier without the bass boost i imagine the mk II would be more like that. but does not have much vertical height or layering to me
if you want thumping bass neither is good for that. but both can reach very low and very high quite effortlessly. the re400 to me has better detail, easier for you to pick it out various aspects with listening. while the gr07 is kind of in a sense pushing it to your face (this is very minor, the klipsch s4 does this to a whole another degree, makes it very splashy, and indistinct)
i think the 30$ if anything would go toward the cable, the y connector and adjustable nozzle and the supreme amount of eartip sizes and ear guides. both are easily fitted but i think the gr07 would appeal to more (the cable is much nicer and sturdier) the nozzle will basically fit anyone of all different ear canal shapes
the re400 has a very nice j shape jack. very sturdy but i honestly think the cable should be replaced. but for 99$ thats such a small quibble considering how much sound quality you get for that price
mind you i use both over ear so microphonics is low for both its no bother
