Earphone Effectivity?

I'just have my Android earphone. HTC earphone, and then I' try to listen up some doses.
Nothing happened. Except for Orgasm.
When I'try orgasm, sometimes It works!
but when I try doses like Brain+, Opium and some other doses, it doesnt work for me.
So what do you think for effectivenes?
Headphone vs Earphone?
