Something else that you ought to know, is that if your previous IEMs have more bass than the new ones, then your brain/ears is going to find the newer pair lacking in bass quantity. Your have to go through a period of brain adaptation to the amount of bass that your IEMs have. The WOW factor disappears to a significant extent after you we get used to big bass earphones. The disappointment bass factor disappears to a significant extent after we get used to earphones with less bass than we are used to.
Yeah I'm afraid your right. I listen to a lot of music that is bass dependant, such as Chillstep, lounge, some dubstep, hip hop and then a little bit of everything in between. I shouldn't be judging them until I get the new tips on them and at least 40 hours of play time. I really don't feel i'm getting a good enough seal.
I wonder if I should try the GR07 BE or some other headphone that has great bass.
I really really want to try the XBA-40... but they are expensive and source dependant. I don't amp, just play from my iPhone and MacBook. I don't know how much I will like their warm, thick sound signature, but heard they have phenomenal bass and clarity.
