Is there a bluetooth headphone that allows phone calls and would enable me to listen to my podcasts during my daily commute? I'm talking about the "one ear variety" I really would like to go wireless without having to carry my standard wired earbuds as well as a blue tooth head phone. I did some research but the only thing I'm coming up with is the "two eared variety" that you use at the gym or casually hanging out listening to music. Any suggestions would be greatly appreciated. Also if they don't make the "one eared" variety please let me know.
