walkie talkie and cell phone headsets

Does anyone know if there are any (cheap) cell phone headsets that can be used on walkie talkies, or if this action can even be performed at all. I need to buy a bunch of them and don't want to spend the money to purchase walkie talkie headsets. Any help would be appreciated.

 

i dunno if they can be compatible w/ each other
