Not hard at all. It came out relatively easy. The glue that holds them in is not vey strong. I used mini flat nose pliers to grab the driver and wiggle it out.

Well, I ordered the black MH-755 before assassin10000 reported them being fakes. I decided to do a tear down and a comparison between the real one and fake one. Here are the pictures. They look the same on the outside and the housing looks exactly the same inside and out, even the vent holes...

Thanks!

Hey, I too have a extra set of MH-755 drivers laying around from a failed first time mmcx mod attempt. Can I ask where you got those metal shells? I am interested in doing similar with my drivers.

absolutely. Its really flexible and has a little firmness to it.
