Firstly, I had two wires of Sennheiser MX500, It has a volume control! I was broke the earphone, but wire is like new. The wire is asymmetrical, so cut the longer side as same as the shorter side.

Then, open the K26P, solder off the original wires, and solder the MX500 wire on.

Here has some photos of the works:
