try hardwarezone forum, go under portable media player.
there's also sgheadphones.net, but the discussions generally cover
higher-end stuff.
it's hard to say what is better. depends on personal preference and
budget.
so far i've kept my earphones purchases below $50. creative ep630
and cresyn e630 (korean). both are canalphones.
i've tried these sennheiser px100 headphones which came free with
my samsung player purchase, and they do sound good. just that they
don't provide sound isolation, and they mess up my hair, so i gave
them away. this is in the $60-$80 range.
for audio-technica, the ck-7 has been praised by many. this comes
under the low $100 range. the lesser range from audio-techinca is
seldomed mentioned, so you know what i mean.
if you are ready to invest, there are many brands to look into. my
humble experience in reading up spells westone, shure, ultimate
ears, etymotic. these are all in-ear monitors.
