take on the Iphone earbuds

I am often shocked with how incredibly stupid people are and even that statement shocks me.. 

 

Take today as an example, I am walking to work and see some dude standing on the sidewalk using their white earbuds thing to talk on their IPhone.  Now this in itself isn't that crazy but what is ridiculous is that this dude was still putting his phone right up to their mouth.. what exactly is the point to having to wear those earbuds if you are just going to give yourself an arm cramp by holding the phone mic right to your face.  

 

This is similar to the people you see driving using the speaker-phone option on their phone but still holding the phone in their hands.    Somebody please explain to me how anybody could consider this 'hands free'
