I think the price difference between EP630 and Bijou should explain enough. Assume that more expensive normally means better product, although not all the cases are

One aspect that Bijou might be superior to EP630 is the clarity. The bass no idea yet
EP630 wins over ATH CK32? Wow, surprising that Creative Labs can produces such quality budget IEM. I always thought that Audio Technica is a premium brand in headphones, you know like the Sennheiser

Guys, roughly how long I need to burn the earphone? Just got it today, and read the burning FAQ, burning it now.

So far got any significance difference before and after burn in?

Wahahah.... approx 2 weeks to burn it.... I think I just used it for 1 hour +.... still got 99 hours left for burning.
Just wait and listen la... 

Don't you guys find EP630 a little too bassy? Seems cool in the beginning but after about 1 hour or so, it gets too muffled.

A good earphone does not need EQ adjustment. Some refuse to play with the EQ because they want to keep music as it is in original form instead of distort the music. EP630 is bassy for me, although its fine with other listeners. Reducing bass in EQ will distort your music, which I prefer not to do.
The EP630s in eBay are located in China, and sell at half the local price. Come on, by common sense if its cheap and located in China, you know its too good to be true - I believe they are fake EP630. In Malaysia also has many fake EP630s circulate in our market. It is hard to find original ones, even in Lowyat Plaza the retail shops there were fooled to think they were selling original EP630s until the buyers found out they're fake actually.
I maybe wrong however, as the eBay seller has POWERSELLER batch on his/her chest

In the context of retail market, RM99 can be considered ok la because I also found other shops in Low Yat Plaza sell EP630 more expensive ranging from RM150-RM190.
However in the world of internet shopping RM99's a little bit expensive. I bought mine in internet at less than RM60 (including shipping charge) and yes it is original according to other many buyers (and me).
To be honest it is not easy to detect whether its original or fake. Try read some more on others EP630 user's experiences in this thread to get the picture of how the original sound quality.
EP830 claimed by Creative Labs as premium canalphone. It is shipped together with Creative Zen X-Fi. So price-wise, if EP630 is a budget model, you can assume or expect better from EP830. Hard to be specific about EP830 sound quality as I have not found any reviews yet about it and not many using it too.

hi guys...
wanna ask...
how u guys store ur earphone?
i know ep630 comes with a pouch...

so...when u not in play with ur mp3 player...
do u unplug the earphone from the mp3 player...
and then simply bend ur earphone and put it in the pouch...
and then put ur pouch to ur pocket...?

coz i would like to know more on how to keep the earphone...
coz the earphones i used...always got problem very fast...1 side of the earphone always stop producing sound...

One forumer suggested use old radio to burn in, Dry Pillow is that you?

Still burning the earphone, but now i've lost count how many hours passed..... I wanna compare it to SG EarPump.

For new EP-630 owners, you really should burn in the earphone to achieve the best sound it can offer. 

new, well dunno whether new or not, user of ep-630 reporting! just got mine from Dybre. feels so much better than the fake ones lol, even the earbuds are softer!
