acidtripwow, so how do you use them? NC20 when the size of them is ok, otherwise the EX70's? John

Yes, I've read that the EX70's *should* probably be better, and that I should save up for the Etymotic ER-4's! I'll need to get my head round spending that much first (no pun intended). Meanwhile, anyone got personal experience of the EX70 vs NC20 as I've an opportunity to get either? John

Ok, I know the NC20's are active headphones and the EX70's are passive in-ear phones, but has anyone tried both and can comment on their comparison for - Noice reduction performance - Sound quality Thanks John
