I LOVE IT!!!! This has to be one of the best things I have ever gotten on amazon. Not only does it work with my walkie talkies, but I got a 2.5mm to 3.5mm adapter and I can plug it into my ipod and play music!  I haven't tried it yet but, I am interested in seeing if I can plug it into a 2 pin walkie talkie and use it to talk only, then plug in headphones into the other jack. The only complaint is the length of the cord, so I can't wear it over my shoulder, but I can wear it on my shoulder but the cord has to go underneath my arm.
