You have basically answered the question yourself
You're in singapore, right? I'm sure if you shop around you will find them in your local stores, as the edifier is a more common brand compare to the chinese earbuds like the emx or the graphene. Heck, even computer stores sell edifiers
Compared to the emx, the H101 has a more distant sound. Image you are sitting in the middle a movie theater (speakers far on the walls), while the emx is more like sitting in a small living room with surround speakers around you. Both have good staging, just that the emx is closer. Personally, i prefer the H101,but your preference might be different than me.
Can't comment on the graphene as i have sold it.
Please do post a review when you did decided to recable them.
Yes, that sub bass.. Try watching action movies with them, or better yet, asian jump scare movies!
