Why is it that there are separate earphones for Android and iPhone?

A. 1

Listening to music itself works equally well for both Android and iPhone.
It's just whether a switch or something works.

A. 2

It depends on whether the buttons such as answering the phone, adjusting the volume, and starting the music work.
Music can be heard equally well.
