right now evo 4g. when/if iphone5 releases ill be getting one of them.
only reason why headphone style wont work really is movement and such. i hate headphones.
if i was sitting in the car or literally at a desk not going to move id use them. but i go from field environment to my desk to driving to field environment again all within minutes at times, something like headphones thatll be a PITA with coat on coat off kneeling under this or that, taking a dump, and etc isnt an option.
i know i need a bluetooth one, the question is which ones are absolute junk and which ones arent. i wanna be able to hear the person and them hear me. it doesnt need to be the best HD audio in the world. just got to allow me to talk while im using my hands doing various things.
