I don't see how this poll will do any good. Some people are going to feel biased to choose whatever phone they have, regardless if they heard the other one or not. CX300 people would want to justify their purchase and ep630 folks want to feel they got one hell of a bargain. There shouldn't be a poll and it should just be a thread for people who've actually heard both of them.

CX 300 has more transparent in sound, it provides cleaner and cooler backgroud, a little bit wider space in head. now, I become more appriciate this in some good recording CDs. the more I listen, the more I feel their different characters.
