if you are more inclined towards bass effect then CX is good but i found it low on max volume...EP has both but it lacks the bass depth....its ur personal taste.....i have JBL Reference 220 in-ears , came with a cute case with all the add ons, sound clarity is awesome as compared to both these....next buy amg Headphones will be JBL 440 for me.....but both the jbl's m talking about will surely burn a hole in the pocket.....
same here but me got the XBi, sound quality awesome!!!!bass much much better than the ep-630's i previously used!!!!but thn its more than 2.5 times s=costlier thn the ep630!!!ur call
