Just received my J3 and...
i'm having mixed feelings about it... i come from a sony walkman x, and somehow i find some good and bad things about the SQ on the J3... better instrument separation, DEFINITELY less noise, and i hear things that i couldn't hear before on my music... but still... there's something that doesn't sound right to me, like the sound sound a bit "tinier" (is that the word?) than the sony x.
I read somewhere in the forum that sony uses a "fun" sound, might that be it? does the J3 need a while to "burn in" like headphones? if not, maybe i just need to get used to it, i have to admit the sound customization is nuts tho xD
By the way i'm using panasonic's HJE900 iem (already burnt in with my old sony x).
