all right final impressions
ex083 vs gr07 mk2
bass quality and quantity ex083>gr07 mk2
soundsatge=same
mids gr07>>ex083
highs gr07>>ex083
but 083 have no sibilance and are very very enjoyable.
i am serious when i say that for rock,pop and rap these are better than brainwavz m3 which severely lacks in soundstage and bass.
i also purchased mh-1 believing the hype and i must say i am pretty disappointed.i paid about 30$ for oem version with no warranty,then bought a 8$ omtp to ctia converter so all in all 40$ for these.
sound is ok but the biggest prolem is that they need a lot of power.my clip+ at 0 volume(u know what it means,0 db for rockbox after which + volume starts) sounds a bit loud when while using gr07 mk2 i don't go beyond -11 or -12!!
bass as compared to brainwavz m3 is more but quality is lacking.compared to ex083 and gr07 its totally lacking in quality and quantity.
mids are fine,a bit muddy compared to gr07.m3 but better than ex083
highs are pretty smooth like m3,maybe treble lacks a bit of extension vs gr07,again better than ex083 marginally.
but still on an overall scenario for rock,pop and expecially rap
gr07 mk2>>ex083>>brainwavz m3>>sony mh-1
for vocal intensive songs having no drums or little bass
brainwavz m3>gr07 mk2>>mh-1>>>ex083(but m3 have a really weak soundstage so preference may change)
if u guys think mh-1 has huge bass then just listen to gr07 and especially ex083,damn now thats called a punchy bass

clip+ rockboxed
update:
for the relaxed listening without thinking too much into technicalities
brainwavz m3>sony mh-1(both are unoffensive with liquid smooth treble and no sibilance at all)>gr07 mk2>ex083
gr07 mk2 has more sibilance and the drums are damn punchy especially if u listen to TOOL,METALLICA,OPETH
they are more enjoyable too but for long listening one may get fatigued but i typically never listen to same set of genre,i shuffle between indian,western,rock,pop,rap so its not really a problem
