stupidest looking earphones ever designed? at least one guy bought them!

here's an old one out of my phone camera that I never got around to blogging....

a few months back I was on the MTR and I noticed something strange on the guy standing next to me in the train. 

My years of practice allowed me to surreptitiously snap this photo:

whats that? some kind of clip on his ear with a wire coming out? what the hell is that?

I couldn't fathom what it could be... not an earpiece? bone conducting headphones? maybe a heart rate monitor or some sort of medical system? 

Then a few stops later the guy sat down and I got the full view:

WTF?!?   they're clip-to-your-ear headphones?  (he was playing with a phone or mp3 player connected to these things).

Totally ridiculous looking! who would buy these things?  who would use them in public even if someone gave them to you as a present?   Has anyone seen these before?  I can't even find anything like this online.

Looks like he's about to try and jump start his brain. :-D

Would you wear headphones like this?
