I researched the subject a lot last year. It turns out there are 800 dollar quality devices, and maybe 60 dollar cheap helmets with walkie talkie functionality that wouldnt fit your head. There isnt really much in between. So I bought a good fitting helmet and i bought hands free speakers made specifically for that helmet. So i can now connect my speakers to my cell phone to use as an mp3 player or to make calls on the road. If theres a walkie talkie app i can download one of them too.
