I know this comes up as a regular thing but I have an ongoing quest for The Platonic Ideal earphones for running.
I've tried the ones that clip on behind the ears, and the ones that have little prongs (which turn out to be rubber) that slot into the whorls in my ears, and neither seems to stay put sufficiently that I'm not constantly trying to prod them back in.
I'd prefer not to pay loads, as my experience earphones in general (which is *a lot of pairs*) is that unless you're sitting in a quiet room, you don't get that much better experience, but I will if someone can convince me it's worth it.
So what types/brands/cunning tricks do people have for earphones?
