That is all everyone has been giving you in this entire thread. It is like choosing the type of cloths you want to wear of the type of food you want to eat.
So you have to just go with what you think will be nice for you. You want a bassy earphone and if you want one that is an upgrade to your FX101. Try out a FX3X. A side grade would be something like a SHE3580 or even better the SHE9700.
