hmm 660 is 150x2 ohm. weird for 668b eh

no worry, higher impendence doesn't mean better in sound quality also. Need to get both and hear which is better for your music liking. Lol

Here's the only thing I understand about impedance.
Higher impedance, require higher voltage but lower current, and has less volume.

hahaha yea i know. what i meant was both of those headphones are similar. so its abit weird for 668b driver rating to be so low

well for me 668B lower impedance means better cos no nid too much power to drive

hahaha yea. means pmp can power up these babies. maybe thats why 660 mids are recessed without amp

dunno if da cheap fiio e5 can drive da 150 ohm hd330 anot...

tomoro i try use e5 to drive 660 la. XD

u mean the 330 eh? all the models sometimes very confusing
let us know later bro, but im guessing the e5 wont be able to push it very far, need better one maybe

i believe 668b's lower impedence has it's own advantage too. Because it can both be power directly via standard pmp and also with added amp it would gain much better sound quality. Even thou with the low impedence.

thats true, i pair with my gumstick is already good sounding now
a good combination i would say
for me i dun like messy amp source, just don't like too many devices, kinda messy for me (just my preference, may not be for others)
that's why im still soul searching for a player that both my players features (bluetooth and gumstick Flac powah) so i can stick to just 1 player
but the seller so dam slow to reply even tho i already asked 3 times, it's like he's not gonna answer me soon
slow seller i would say even though he's online!

Not everyone like me hahahahaha joking. anyway 330 and 660 should have same driver i think. so 660 result should be similar to 330

yeah should be same
waiting results from you all then hehe

yea, better try it... both 330 n 660 hav same driver... should hav almost similiar sound... if E5 can drive it pretty well, then i should not bother 2 get another amp A.S.A.P... can relax n use my E5 1st... when cash is ready, then only get a better amp

Yea, they probably have the same driver, bro camrycilver posted the specs back in #231. The 330 is semi-open whereas the 660 is closed back so they shouldn't sound the same. I reckon one will be more airy while the other is 'tight'.

Will be a HD381F owner soon.

grats

hmmm... wondering wats da results, bro trio? any gd???

at first,i bought 1,then i order 2 more HD681

sorry ah guys i am having my finals rite now. so will have delay in everything
